Leak-Free Thread Adaptation for Your Catch Can Setup
The Mishimoto MMFT-M20-34BK fitting set adapts an M20x1.5 threaded port to a 3/4 inch push-on hose barb, letting you connect 3/4 inch CCV or PCV hoses to a catch can with M20x1.5 threaded ports, such as the Mishimoto Universal Baffled Parallel Port Catch Can. Each fitting is CNC-machined from 6061 aluminum and finished in a black anodized coating for long-term corrosion resistance and a clean, factory-quality appearance.
