Pro-source PC68-DOT-44 Brass Push-to-connect Fitting

Product Description

The PRO-SOURCE PC68-DOT-44 is a straight push-to-connect tube fitting machined from brass, designed for general-purpose pneumatic and fluid line connections. It features a push-to-connect inlet for 1/4-inch outside diameter tubing on one end and a male NPT threaded outlet on the other. The DOT rating indicates compliance with Department of Transportation standards, making it suitable for air brake and pressurized transport system applications. The overall length is approximately 26.70 millimeters (roughly 1.05 inches). Plumbers, HVAC technicians, and pneumatic system installers use this fitting type when a quick, tool-free tube connection to a threaded port is required.

This fitting is suited for general-purpose applications where 1/4-inch OD tubing must terminate at a male NPT threaded port. Common install scenarios include compressed air distribution, pneumatic control lines, and DOT-compliant air brake tubing assemblies on commercial vehicles and equipment. The push-to-connect design allows fast field assembly without ferrules, compression sleeves, or special tooling, reducing installation time on high-volume or service work.

Key Features

• Straight push-to-connect to male NPT configuration for direct port connections
• Accepts 1/4-inch outside diameter tubing with no additional ferrules or sleeves
• Brass construction offers corrosion resistance in air and compatible fluid service
• DOT-rated for compliance with Department of Transportation pressure line requirements
• NPT thread type ensures broad compatibility with standard threaded ports and fittings
• Compact overall length of approximately 26.70 millimeters suits tight installation spaces

Compatibility

Designed for general-purpose use with 1/4-inch OD tubing and standard male NPT ported components in pneumatic and DOT-compliant air line systems.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified pneumatic system technicians. Depressurize and isolate the line completely before removing or installing any push-to-connect fitting. Ensure tubing is cut squarely and deburred before insertion to achieve a proper seal. Apply thread sealant to the NPT threads in accordance with applicable codes and the fitting manufacturer guidance.
