Designed for use with our Universal Baffled Parallel Port Catch Can (Link to MMBCC-PPTWO) these fittings adapt a M20x1.5 thread to a 5/8" push-on hose barb to accommodate 5/8” CCV/PCV hoses. They are made from CNC-machined 6061 aluminum and feature a black anodized finish for superior durability. The threaded end is sealed with a Viton™ O-Ring for secure leak-free fitment. For added peace of mind these fittings are backed by the Mishimoto Lifetime Warranty.
