Permatex Ultra Blue Silicone Automotive Gasket Maker - 75724

I've always trusted Permatex Gasket Maker for my projects, and it hasn't let me down. It's perfect when you don't have a gasket or just want that extra bit of sealing confidence. Easy to use and holds up great. On top of that, Walmart shipped it out super fast, which was a huge plus. Definitely recommend!

This review is for the Permatex Ultra Blue Gasket Maker Multi Purpose. Part 81724 comes in 3.35oz metal tube with screw on top. My husband used this to make a new seal/gasket on extendable pole chainsaw. This worked fabulously. Save money and time so you don't have to order the manufacturer gasket. We have cut with the chainsaw a number of times and this has held up well- no foreseen issues. My husbands favorite part is that you can just screw the cap back on and save the rest for a later time. This gasket maker works for temps -65 through +500F. This is sensor safe RTV silicone and meets OEM specs.

Great stuff! Permatex Blue is an all purpose sealant and gasket maker. I have used Permatex Blue to completely seal a couple of vehicles for friends and family. When you want to do the job right this is the stuff to use. Adheres nicely. Highly recommend to keep on hand.

I didn't have to make a full gasket, but only needed to seal four seams prior to installing the new oil pan gasket. I followed the directions and the product worked fine. I've added oil and heat cycled the engine multiple times with no leaks at those seams.

This stuff is truly a life saver. I originally got it as its always good to keep in home with a mechanic as a husband. Little did i know i would have a leaking faucet and would be using this to seal it until my repair person was able to come out and replace my pipes. Made sure to dry and sand the area some first. Then i applied and let sit over night. Worked wonderfully.

This is one of few products I've used that produced excellent, long lasting results. I over did it the first time and ended up with a mess. When I used it correctly as directed, I got a perfect, non messy, long lasting seal. Most recently, I used this to seal the connections on my hot tub heater. The stainless steel to PVC connections are neat, leak free and easily handle the heat.

This product works excellent! I would definitely recommend to anyone working on a vehicle. We use this at my work and all the maintenance personnel look for this brand as their preference. The tube of product and spout work well every tube, never had a bad tube or one I couldn’t dispense nicely.

Actually got this to try to make a gasket for a vacuum cleaner. I traced the exterior shape onto 2 sheets of thin paper and then cut with razor/exacto. Then, spread silicone along outside of one proto and using rubber gloves dampened with water, I smoothed it as best as possible. It has the similar/better consistency to/than silicone caulk. I put the 2nd traced sheet of paper over the silicone and the sandwiched paper in the tube and closed. Allowed to dry for approx 1 1/2 hrs and then cut center of paper for hole. It worked really well. Vac has better suction. It also gave me a great idea for removable, reusable silicone weather strips from for windows in the winter.
