Service Caps & Plugs
When you crack a line open, dirt gets in and oil gets out. Our selection of service caps and plugs seal ports fast on JIC 37° and 45° flare, NPT, SAE straight thread O-ring, flat face o-ring and Code 61 and 62 split flanges. Go threaded for a positive hold, push-on for speed, silicone when heat and solvents are in play.
