SKU: NMP-01002 Category:


Easy to install, reuseable, no-mess solution for sealing your exhaust to the O.S. 1.05 engine crank case. High temp fiber gasket material creates a great seal that will not blow out over time.

*Includes 3 gaskets

Fits all O.S. .61, .91, 1.05 Engines and Exhaust

One key variable to good engine performance is a leak free exhaust, RTV and other high temp adhesives can be messy, time consuming, and inconsistent. These gaskets bolt right on and can be reused multiple times when removing the exhaust system.

*** Clean both sides the engine exhaust port and exhaust header well before installation. NO NOT soak in oil before intalling.

Tighen the exhaust snuggly and only compress the gasket a little bit. After the first flight with a gasket, immediately after landing while the engine is still warm, re-snug (don’t crank down) the exhaust bolts, let cool completely and the exhaust will stay tight until you go to remove it next.

    This is absolutely the best solution for a perfect exhaust seal!!
    No messing with RTVs anymore, having to redo it every time you remove the pipe.. basically just set it and forget it.
    I’ve removed mine multiple times already and the gasket still in perfect condition!

    I have tried every possible method for sealing the exhaust on my helicopters, with little to no success. Until I picked up a package of Nick`s gaskets. These things WORK! No mess, no hassle. Just install it, run the engine for a good hard flight, and re-tighten the muffler bolts…done! If you don`t have these on your helicopter, you`re doing yourself a disservice.

    Truly an amazing product. Thank you Nick for developing this. I was so sick and tired of cleaning up RTV and resealing every 20 or 30 flights. JB weld worked a little longer but would eventually fail and that was even more work to clean up. These gaskets are an awesome solution for a well tuned engine.
