Gasgacinch Vs. Permatex: In order to compare their difference, I conducted tests among different gasket sealers.
In terms of adhesion, the top performers were 440-A and 81158, with 80062 falling in the medium category. Unfortunately, 82194 had almost no adhesion.
When it comes to sealing capabilities, 81158 emerged as the clear winner, followed by 80062 and 82194 in the medium range. Surprisingly, 440-A had the worst sealing performance.
Gasgacinch Vs. Permatex: What’s The Difference?
Considering these results and my personal experience, if you’re dealing with new contact surfaces, I recommend using either 440-A, 80062, or 81158. However, for a better seal, I found that 81158 outperforms the others. It may come as a surprise to some, but not to me, as plain old silicone has been my favorite for over years
My Hands-on Test of Gasgacinch Gasket Cement
After setting the gasket in place, I waited for about 5 to 10 minutes before completing the assembly. It’s essential not to go overboard with the application, as a little goes a long way, ensuring a reliable seal.
In fact, I used it on paper and fabric gaskets during a complete engine rebuild of my 2007 Hayabusa. After putting about 200 miles on it, I’m happy to report that I haven’t experienced any leaks.
Recommended by Edelbrock
What’s impressive is that Gaskacinch is recommended by Edelbrock for the installation of performance intake manifold gaskets. It speaks volumes about its effectiveness and reliability.
When it came to replacing the cylinder head covers on my VW Vanagon, I faced a challenge. Holding the gasket in place during installation was nearly impossible, and my initial attempts resulted in oil leaks. That’s when I decided to give Gaskacinch a try. I followed the instructions, cleaned the head covers, and applied Gaskacinch as directed. The result was perfect. It held the gaskets in place during installation, and even after driving 1500 miles, there were zero leaks.
Ease of Use
Now, let’s talk about the performance of Gaskacinch on various materials. I’ve used it on paper and fabric gaskets during the restoration of a 1958 VW Beetle. It provides the extra help needed for paper gaskets, and its appearance and smell resemble industrial rubber cement.
Using Gaskacinch is a breeze. It’s easy to work with, and cleanup is a breeze as well. Just make sure to use it in a well-ventilated space to avoid the strong fumes.
I believe the container of Gaskacinch I have will last me a lifetime. In the VW community, opinions may vary, but personally, I use Gasgacinch 440-A Gasket Sealer as an loctite 518 alternative on pushrod tube seals during rebuilds. It dries quickly, and I appreciate the old-school label design that resonates with the vintage vehicles I work on.
However, I must mention that the fumes are quite strong, so it’s advisable to open a door or window when using the product or performing the work outside. Additionally, the lid of the container features a synthetic dauber similar to PVC pipe cleaner/cement containers, making the application process convenient.
FAQ of Gasgacinch Gasket Cement
Q: Has anyone ever tried using Gasgacinch 440 to
attach Rubber Knee Pads to a Motorcycle Gas Tank? What were the outcomes?
A: To my knowledge, I haven’t come across anyone using it for that purpose, and I don’t believe it would be the most suitable product. I would suggest considering Barge Cement or Aquaseal instead. Here’s my tutorial on how to use barge cement.
Q: My carburetor is no longer sealing properly. Can I apply Gasgacinch 440 to coat or saturate the gasket to fix the issue?
A: If your carburetor is not sealing properly, there may be an underlying problem beyond just needing a “gasket seal.” Without examining your car, I can’t provide a comprehensive solution through a simple comment. In cases where both the manifold and the carburetor surfaces are flat, you may not even need a sealant. As a diesel mechanic with 30 years of experience, I can say that Gasgacinch 440 has been one of the best I’ve used. I typically apply a coat on the gasket and the corresponding part, allow it to semi-dry until tacky, and then assemble the components.
Q: Can I use Gasgacinch 440 to seal the connection between the radiator hose and nipple connector?
A: If you’re experiencing a leak in that area, it would be advisable to replace the hose rather than relying on a sealer.
Q: Is it suitable for sealing the bead of a tire when replacing it? Is it more effective than Bead Don, which I typically use for this purpose?
A: Gasgacinch 440 is a light adhesive glue, and I haven’t seen anyone using glue specifically for sealing a tire bead. Therefore, I can’t say for certain if it would work in your application.
Q: Would Gasgacinch 440 serve as a good sealant for a water pump gasket (antifreeze)?
A: Absolutely, it would work well. Just remember to apply it to the pump side of the gasket and not on both sides.
Q: Can I use this to fix a coolant hose leak? Applying a light coat on the nipple didn’t solve the issue with a new water pump, hose, and clamp.
A: If the leak is not around the water pump gasket but rather where the new hoses attach to the water pump, I recommend repositioning the clamp. If that doesn’t work, remove the clamp and hose, inspect the casting where the hose connects for smoothness or rust, and address any issues with plumber sandpaper. These factors, along with a mispositioned clamp, can cause leaks that won’t be resolved by a gasket sealer. In my experience, the most common solution is to reposition the clamp, sometimes with the assistance of a mechanic mirror and flashlight to ensure optimal positioning. Good luck with resolving the issue.
Q: I just received Gasgacinch 440. Should it have a similar appearance to PVC cement? Does it smell the same?
A: Yes, it does have a similar smell to PVC cement, and the color is somewhat comparable as well. However, it is rubberized and doesn’t dry hard like PVC cement. I’ve written an article about how to open pvc cement.
Q: Can I use Gasgacinch 440 on the cylinder head gasket of my Kawasaki ZX-14 motorcycle?
A: While it is technically possible to use it on the cylinder head gasket, I haven’t encountered a need for any sealant or coating on an OEM factory head gasket.
Q: After applying Gasgacinch 440 to the sides of the gasket, how long should I wait before joining the two pieces?
A: The can should have instructions regarding the waiting time, but from what I recall, I waited 15 minutes after applying the product to both the water pump surface and the gasket mating surface. After that, I joined the two pieces and installed the pump. No leaks occurred, and the assembly remained in position.
Q: Can I use it to seal the black gasket on the convertible top that rests against the window? I’m concerned about the visibility and appearance.
A: I don’t think it would provide a secure hold in that application. I would suggest considering black silicone sealer.
Q: How can I effectively utilize Gasgacinch 440 to enhance the performance of my belt? Should I apply it while the belt is in motion or should it be stationary on the engine?
A: Gasgacinch 440 is not designed to enhance the performance of a belt. Its primary purpose is to hold gaskets in place. If you’re looking to improve the performance of your belt, it’s best to follow the manufacturer’s recommendations and guidelines for belt maintenance and replacement. Applying this product to a belt while it is in motion or stationary on the engine may not yield the desired results and could potentially cause issues.
My Hands-on Test of Permatex 81158 Black Silicone Sealant
I had some clear silicone around my black crawlspace vents, which turned out to be an eyesore. Thankfully, this black silicone adhesive stuck right on the clear silicone after I cleaned it with rubbing alcohol and let it dry. To avoid any over-applying on the brick, I used yellow tape that sticks to stone and brick.
Dries to a Matte Finish
When using Permatex 81158 Sealant, you can use the top of the cap to pierce the foil and then decide whether to use it with the applicator or not. It dries to a matte finish, which is great. It works well and creates a strong seal. I used it to cover a gap on my rear spoiler after installation. Properly taping it up and using latex gloves is crucial. Having a wet paper towel on hand for cleaning excess is also helpful.
I found this black silicone sealant/adhesive to be indispensable on my workbench, especially when it comes to light repairs. Unlike instant glue, it’s not brittle and doesn’t leave behind any white residue. It’s perfect for hiding and securing cracked black plastics, particularly when the item being fixed isn’t under constant stress. This product doesn’t have an acetic smell, which is a plus. For minor repairs such as light scratches and dings, I often use black fingernail polish before resorting to it. Both items have a permanent place on my bench.
While there aren’t many brands offering black colored silicone in a tube, Permatex stands out as one of the best. The black color of this silicone sealant does earn it credit.
The adhesion and texture of this black silicone are decent, but I must admit that it doesn’t compare to the GE Silicone II, which is my top choice. The GE Silicone II dries firm yet pliable and has excellent adhesion. On the other hand, the Permatex product can be a little runny and takes longer to dry. I had a project that fell apart when I used the Permatex, but when I redid it with GE Silicone II, I achieved satisfactory results.
FAQ of Permatex 81158 Black Silicone Sealant
Q: Could Permatex 81158 be suitable for attaching EPDM roofing rubber to repair rubber scuba flippers? Is it flexible and water-resistant?

A: While it is not necessary to use a primer with Permatex 81158, I recommend ensuring that the surface is clean before application.
Q: Can I use Permatex 81158 to seal the gap between a sink and a countertop?
A: Personally, I would not use Permatex 81158 for sealing a sink to a countertop. One major reason is that it is an oil-based product, which can be messy and challenging to clean up. For such a project, it is recommended to use a water-based clear silicone sealer, which is a more suitable choice.
Q: What is the ideal temperature and humidity for applying this sealant? The weather is hot and very humid where I live currently.
A: The package does not specify an “ideal” temperature range. However, it does state that the sealant requires 24 hours for full curing under normal conditions. In colder or drier conditions, additional time may be necessary. I personally used this sealant to repair my car door’s weatherstripping in Phoenix, AZ, where the temperature was at least 105 degrees Fahrenheit. It performed well under those conditions, so you should be fine. This sealant is quite versatile and handy.
