Description

The Allstar Performance ALL34146 is a check valve designed for crankcase evacuation systems. It features a 1/2 inch NPT female inlet and a 5/8 inch hose barb outlet.

Constructed from steel with a cadmium finish, this check valve is sold individually and is intended for use with the Allstar crankcase evacuation system. It helps reduce crankcase pressure for improved piston ring seal, fewer oil leaks, and better overall engine performance.
