Pro-source PC69-DOT-42 Brass Push-to-connect Fitting

Product Description

The PRO-SOURCE PC69-DOT-42 is a brass push-to-connect tube fitting designed for general-purpose pneumatic and fluid line applications. It features a push-to-connect inlet accepting 1/4 inch outside diameter tubing and a male NPT threaded outlet, allowing fast, tool-free tube insertion on one end with a standard threaded port connection on the other. Manufactured from brass, the fitting meets DOT standards, making it suitable for air brake and other regulated compressed-air service. Plumbers, HVAC technicians, and pneumatic system technicians install this fitting where a reliable, leak-resistant connection is needed without the time or tooling required for compression or flare assemblies.

This fitting is suited for residential and light commercial pneumatic lines, compressed air distribution, and general fluid transfer systems where 1/4 inch OD tubing terminates at a threaded port. The male NPT thread end connects directly to valves, manifolds, cylinders, or equipment ports with a standard NPT-threaded inlet. DOT compliance extends its use to air brake supply lines and regulated vehicle or trailer air systems in addition to stationary equipment installations.

Key Features

• Push-to-connect design accepts 1/4 inch OD tubing without tools or ferrules
• Brass construction provides corrosion resistance in air and compatible fluid service
• Male NPT thread outlet for direct connection to standard threaded ports
• Meets DOT standards for use in regulated compressed-air and air brake applications
• Compact form factor suited for tight installation spaces

Compatibility

Designed as a general-purpose OEM-style push-to-connect fitting for systems using 1/4 inch OD tubing with a male NPT threaded port interface.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or pneumatic system technicians. Depressurize and lock out the system before removing or installing any fitting. Ensure the tubing end is cut cleanly and squarely with a tube cutter and is free of burrs before insertion into the push-to-connect collet. Apply thread sealant tape or compound to the male NPT threads in accordance with the equipment manufacturer and applicable code requirements before tightening.
