Pro-source PC69-DOT-108 Brass Push-to-connect Fitting

Product Description

The PRO-SOURCE PC69-DOT-108 is a brass push-to-connect tube fitting designed for fast, tool-free connections in general-purpose pneumatic and fluid systems. One end accepts push-to-connect tubing with a 5/8-inch outside diameter, while the other end threads onto a male NPT port. The brass construction resists corrosion and handles moderate pressure in compressed air, water, and compatible fluid lines. This fitting meets DOT standards, making it suitable for use in applications where Department of Transportation compliance is required. Plumbers, pipefitters, and mechanical contractors install this type of fitting during new construction, equipment hookups, and service calls.

This fitting is intended for general-purpose service across a wide range of residential and light commercial systems. Typical applications include compressed air distribution lines, water supply connections, and fluid transfer plumbing where a push-to-connect inlet pairs with a threaded male NPT outlet. The 5/8-inch tube OD size suits mid-range tubing commonly found in HVAC equipment, pneumatic tool systems, and plumbing assemblies. Its DOT compliance makes it appropriate for vehicle and transport-related fluid systems as well.

Key Features

• Push-to-connect x MNPT configuration for fast installation without crimping or soldering
• 5/8-inch tube outside diameter accommodates standard mid-range tubing
• Brass construction provides corrosion resistance in air and water service
• NPT thread type ensures compatibility with standard threaded ports
• DOT-certified for use in regulated and transport-related fluid systems

Compatibility

Designed as a general-purpose replacement or new-installation push-to-connect fitting for systems using 5/8-inch OD tubing and male NPT threaded ports.

Installation Notes

Installation is performed by plumbers, pipefitters, or qualified mechanical technicians. Depressurize and isolate the line before removing or installing any fitting. Ensure the tubing end is cut cleanly and squarely and that the OD is free of burrs before inserting into the push-to-connect end. Apply thread sealant to the NPT threads in accordance with applicable plumbing codes such as the IPC before torquing into the mating port.
