Permatex 51813 Anaerobic Gasket Maker, 50 ml Tube , Red, Packaging may vary.

If you’re not familiar with this sealant it only hardens once everything is tightened up, it’s like a heavy grease when you apply it. I’ve had excellent results using it on split engine cases and as a replacement for a base gasket when you are trying to bump up the compression on something like a chainsaw or other small engine. What i use it for most is on paper type gaskets. A light coat on both sides of a new gasket and it’ll never leak. In a pinch if you pull something with a paper gasket and it don’t tear you can apply this to the exposed side of the gasket and re use it. I’ve done this quite a few times and never had a leak. It is better than using Silicone/RTV in a lot of applications. However I would not recommend it for any application that has a rubber or steel gasket.

This permatex anaerobic gasket maker worked wonders. It's been 6 months since I use this and the seal is still perfect.

Just What My Techs wanted, Great price, Cheaper than the auto parts stores, Works Great, easy to use

Works fantastic on machined fit engines, ie. 2 stroke mercury halves.

Seams to be working great, no sign of any leaks so far. Because it's a Permatex product you can find it just about any where, unlike some other products like Honda Seal or Kubota's proprietary goop. Plus it's Cherry Red and delicious !

Ease of use, sealed things up....ran just a bit short. So could be just a smidge more in it for the price. Looks like more than there really is...so yas all know.

Worked well

Excellent product!

Fast shipping. Great product for my rear main seal repair. Worked great in my 03 Jeep TJ

Excelente sellador, funciona bastante bien, Yo lo ocupo para sellado de monoblocks de autos donde la tolerancia es mínima, y no me permite otro tipo de sellador.

久しぶりに購入したら結構高かった。でも必需品なので。

Does the job very well and being anaerobic it will not block ports or any other hole.

very good works well
