Parker 62PTC-3 Push-to-connect Union Tube Fitting 3/16 in

Product Description

The PARKER 62PTC-3 is a push-to-connect tube union fitting designed to join two tubes of equal outside diameter in air brake and pneumatic plumbing systems. Constructed from brass with a nitrile O-ring, it provides a secure, leak-resistant connection without additional tools or thread sealant. The fitting is rated for 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F. It carries DOT FMVSS 571.106, SAE J2494, and SAE J2494-3 certifications, making it a code-compliant choice for commercial vehicle air brake plumbing. Installed by heavy-duty fleet technicians and brake system specialists, this fitting suits service, repair, and OEM assembly applications.

This fitting is rated for tube-to-tube union connections in DOT-regulated air brake systems on commercial vehicles. Its 3/16 inch OD tube compatibility and push-to-connect design make it well suited for routing and splicing brake air lines during vehicle maintenance or system fabrication. The brass body resists corrosion in under-chassis environments, and the nitrile O-ring maintains a reliable seal across a wide service temperature range. It is sold individually and is appropriate for both fleet service shops and OEM plumbing applications.

Installation Notes

Installation is performed by licensed brake system technicians or qualified fleet mechanics. Before servicing any air brake line, fully depressurize the system and verify zero pressure at the connection point before proceeding. Ensure tubing is cut square and free of burrs before inserting into the fitting to maintain a proper O-ring seal. Work performed on DOT-regulated air brake systems must comply with applicable federal and state vehicle safety regulations.
