DOT Air Brake Push-To-Connect Fittings allow an instant connection of the properly sized nylon air brake tubing to the fitting simply by pushing the tube into the fitting. Tubing size for a fitting refers to the outside diameter, (O.D.) measurement of the nylon tubing. Push-to-Connect fittings are also called P2C or Push-In Fittings. Among the many advantages of a Push-To-Connect fitting over conventional Compression fittings are the following:

• Quick Connect Design: Fast assembly with no tools required. Simply push tubing in.
• Time Savings: Saves assembly time compared to standard compression fittings. No loose parts to handle.
• Fast Disconnect: Hold the release collar with two fingers and pull out tube. No tools required.
• Reusable: Can be connected and disconnected several times.
• Reliable sealing: When using properly sized O.D. Nylon Tubing a full-seal is achieved.
• Secure Tube Retention. Pulling on tubing without releasing the collar only serves to tighten the connection.
• Leak-Free: Teflon pipe sealant pre-applied to male pipe threads (MPT).
• Full flow – No interference as the fittings seal on outside diameter of the tubing

DOT Push-to-Connect Fittings are constructed with an all brass captive eyelet which allows for maximum flow. Push to Connect fittings feature an internal O-Ring manufactured from Buna-N which grips the installed tubing and holds it in place. The brass captive eyelet with extended length is floating and has a machined top end radius for easy installation of tubing. All male threads have a pre-applied Teflon based pipe sealant to provide for easy assembly and a leak proof seal. They have a working temperature range from -40° to 200° F and a working pressure range from vacuum to 150 PSI. They meet D.O.T. FMVSS 571.106 SAE J1131 standard for air brake systems.
