ProTek RC 1/8 Scale .21 & .28 Silicone Exhaust Manifold Gasket Set (Black) (2)
About this part
This is a set of two ProTek R/C Silicone Exhaust Manifold Gaskets, and are intended for use with 1/8 Scale Nitro Engines. The Exhaust Manifold Gasket seals the fitting between the engine port and exhaust manifold and also the fitting between the exhaust manifold and tuned pipe. With the silicone exhaust gasket sandwiched between these hard metal pieces, over time the gasket tends to lose it resiliency as it absorbs the intense heat and vibrations from the engine. As this happens, the exhaust gasket tends to deteriorate and becomes vulnerable to rips and tears which can cause the engine to lose its tune and possibly become damaged.

I don't know what these are for. I have an OS .21tm. these are far lager than that. Might fit a .28. sure doesn't fit a os21. No specs, no nothing. Just a guess. Good luck. Need to put more information out there. Tired of wasting time and money on crap that doesn't fit.
Protek very good quality for the price, use them under hard racing conditions on truggy's and buggy's, without any problems.
Nice replacement gaskets. Always in stock when I need them, no rips or tears even when removing the pipe or header. Price is right in the ball park if not cheaper than a few others. Will continue to purchase this brand as long as Protek keeps this item around,
I use these little guys all the time. Haven't had any problems with them and they last a good while.
I just got these gaskets from A main. I really like the material they are quality, however, they dont go all the way to the end of the engine case. Kind of difficult to explain, they are not bad at all, just not that good either. I wouldnt buy then again. Not what I would expect from Pro-Tek. Their clutchbells, for example, are perfection.
Four of five reviewers rate the ProTek silicone exhaust manifold gaskets positively, citing good quality for the price, durability under hard racing use on truggies and buggies, resistance to tearing when removing the pipe or header, and reliable stock availability. One reviewer found the material good but reported the gaskets do not reach the full length of the engine case, and said they would not buy again. Another reviewer, who owns an OS .21, found the gasket far larger than expected and said it did not fit that engine, suggesting it might suit a .28 instead; that reviewer also complained about a lack of specifications in the listing. Fit is the main point of disagreement.
