The Ingersoll Rand 32246878 o-ring attaches between the valve plate and cylinder on the high pressure side of the 2340 and 2475 two stage compressor pumps.
32246878 creates a leak free seal to ensure no air or oil leaks past the cylinders and into the system. If oil is leaking from the high pressure side of your Ingersoll Rand compressor pump this o-ring may need to be replaced.
