## Description

Permatex Form-A-Gasket #1 Sealant is a fast-drying, hard-setting sealant designed for sealing rigid materials and flanges, or patching holes and joints where permanent assembly is desired. Resists common shop fluids and fuels, with a temperature range of -65 degrees Fahrenheit to 400 degrees Fahrenheit. When a chemical gasket is not an option, Permatex offers a wide range of gasket sealants suitable for applications on both import and domestic vehicles of any model year or performance caliber.

Review: Excellent alternative to silicone, but not a replacement. - Here we have the quintessential old-school gasket "helper" sealant. No tool box should be without it. This sealant is NOT silicone based, which can be a great thing or a bad thing. The good thing is that it doesn't harden and peel off smooth surfaces like silicone, and it doesn't stick things together like glue like silicone. Be sure you're using it for it's intended purpose. For me, I use it to lightly coat paper gaskets used with oil or water. Just a smidgen on a gasket goes a LONG way. If the sealing surfaces are extremely flat and true to each other, this will work great as well, even without a gasket. If there are surface irregularities, silicone might be a better plan. Just like silicone, this gasket maker can cause gaskets to "squirt out" when tightened, but my experience is that it does not do so as badly as silicone since it's less of a lubricant in it's "wet" state. The good thing is that if you let the Permatex #2 "set up" for an hour or so, before installing the gasket, it does much better to help increase the seal, whereas silicone simply turns to a solid mass and doesn't add to making the gasket seal better. Wear some gloves if you don't want this stuff to get all over your hands; it doesn't easily come off with soap and water, but acetone will remove it in short order. Perhaps the best thing about this stuff is that unlike silicone, it is far less likely to turn to a solid mass in the tube before you have a chance to use it again.
Review: Works well on all my bikes - It feels funny to leave a review for this product. Not because it does not deserve one, but because it should be a household product in every garage of the family back yard mechanic. This stuff works great. It has an incredibly long shelf life (I had to buy another one because I lost my other one! It's kinda like the 10mm socket! LOL). It is easy to apply. The adhesion is good. I really like this product, as always.

## Questions & Answers

**Q: Is this resitant to fuel? I need it to repair a gromet on fil tube gas tank**
A: In my case it did not work with alcohol based fuel.

**Q: Can I use this to stick a metal gasket to an intake manifold?**
A: Metal gaskets are a one use crush type seal.
I would not recommend using permatex #1
Hard setting. You will have an impossible job
Removing the intake without damaging it if
In the future you need to remove it. And
Most likely it will have a vacuum leak!

**Q: any reason it won't work on flange of swimming pool pump?**
A: It may; but containing solvents not designed
for swimming in, I personally would choose
Marine silicone products!

**Q: would this work in water?**
A: No. It need dry air to setup
