ProSeal Sealpro 80726 High Temperature RTV Silicone Instant Gasket, Red

Used this on a water pump in my jeep, solved the problem, no more leaks.

The gasket holding the glass in place had come away around one corner. After watching "Re-sealing oven door glass" video on YouTube, I bought this stuff.Was expecting delivery in 48 hours. Arrived next day!Dismantled the door, cleaned everything up and applied the instant gasket. Left it overnight with plenty of weight on top. Used a craft knife and some steel wool to remove the excess. Job done! And I've only used about 1/4 of the tube.I ran the oven all day on slowly increasing temperatures up to full blast, then down again. The gasket's expansion did bleed through a bit, so a final trim was needed. Other than that, this stuff has replaced the original gasket with something far better and more secure.Great product. Good price. Delivery time exceeded expectations!

Reliable sealant

Worked perfect, should have ordered black though, wouldn't have been more discreet

I needed to re-seal the sump gasket on my focus. Ford don’t use a gasket so you have to use a sealant. Previously I used another brand and it leaked despite getting rid of all traces of the old one. No such problem with this - now it’s nice and leak free again

Very good service and would definitely use again. Thank you.

I have a 1945 Lister D orchard sprayer, and the housing for the pressure relief valve is made of brass, so thus cannot cope with too much tightening of the bolts. even a paper gasket will leak, but by using this sealant, and following the instructions, you can create a beaded seal, loosely tighten the bolts, allow to cure fully ,then tighten gently further. This has proven to stop my leaks 100%, as I am able to achieve a good strong seal, without too much bolt tension, which would otherwise cause the brass cast housing to bend. (noting I levelled the surface first using a whetstone block, as the previous owner had caused considerable damage by over tightening the bolts, causing the housing flanged surface to distort.

The RTV itself is top-grade, one of the best out there.However, it appears the company has a legendary fascination with running a major scam, there needs to be an official investigation as I do believe this is a fraudulent intential failure (motivated by profiteering at the consumer's expense)...what you may ask is the issue?The CAP!I've used a few different types of ProSeal, and they all have caps that literally deteriorate on you after a couple of uses! The caps expand at the bottom to crack vertically, or they crack along the middle all along the circumference, effectivly preventing sealing the tube meaning it all dries up near the top and has to be peeled out each time.I have cheaper toothpaste tubes here, and their tops turned tight at extreme strengths, not even just mere light pressure on closing, and their caps last for months of daily repetitive use!When it comes to anything glue relative, some big brands have a fascination with giving you poorly designed caps so that you repeat the purchase rather than repeat the usage of the tube/bottle!I jumped across to JB Weld, so have millions of others, because after some investigation (discussions with builders/mechanics), it appears this 'weak-cap' issue is generally considered across the industry as one of the longest running scams and people jumped the brands still playing this game a long time ago.If you find this revelation helpful or in-line with your experience, please do mark this review as helpful so that more people know about this, because this 'scam' needs to stop!
