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(TM) O-Ring for secure, leak-free fitment. For added peace of mind, these fittings are backed by the Mishimoto Lifetime Warranty.
