ProTek RC 1/8 Scale .21 & .28 High Temp Silicone Exhaust Manifold Gasket (2)
About this part
This is a pack of two ProTek R/C "High Temp" 1/8 Scale Silicone Exhaust Manifold Gaskets. These are the gaskets supplied with the Samurai 321B engine and tuned pipes. These high temp gaskets are perfect for nitro competition or heavy use.
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.
Also available in a ten pack: PTK-2626

exact fit for nitro motors what else is their to say
These are OS-brand OEM gaskets, the same as the ones you'll find on brand new OS engines -- in other words, they're the best. Worth the extra dime over the standard Protek gaskets, which are a bit plasticky and seem to wear much faster. You bought a $500 engine, why go cheap on the exhaust gasket?
Fits all tuned pipe-header coupler, for the engine -header most except Pico and Reds engines, one of the must important parts to get fine and correct tune of your engine, its an expendable item that sometimes is overlooked, Protek RC did a great manufacture, fit and finish on this gaskets, and incredible price, great value-for the money!
Great replacements for your O.S. engines, these have great fitment and will last quite a while. Keeping up on gasket maintenance is important! keep these on had so you don't have cracked/ torn gaskets and keep your engine running great.
I'm sure they're great, i gave them a shot as someone else mentioned these were the exact OS brand gaskets just relabeled and repackaged. Bit to big for the OS .21
Reviewers generally report that these silicone exhaust manifold gaskets fit nitro engines well, with most rating them 5/5 from verified owners. Several describe them as good value and note the importance of regular gasket replacement for maintaining engine performance. One reviewer claims they are repackaged OS-brand OEM gaskets and says they are better than standard ProTek gaskets, which were described as plasticky and wearing faster; another reviewer, rating 4/5, says the fit was too large for an OS .21 engine. Reviewers also note compatibility is most common with tuned pipe-header couplers, with an exception for Pico and Reds engines. The origin claim is not verified in the reviews.
