Parker PF-00075 Push-to-connect Fitting 3/8 in Brass

Product Description

The PARKER PF-00075 is a push-to-connect tube-to-male NPT tube fitting machined from brass and rated to 250 psi maximum working pressure. It provides an inline union between two tube runs and a male NPT threaded port, allowing a technician to complete a three-way connection without compression fittings or soldering. The 3/8-inch outside diameter tube ports accept tubing with a quick push-lock engagement, while the 3/8-inch MNPT port threads directly into a valve body, manifold, or equipment port. The 3/4-inch hex provides a standard wrench flat for controlled installation torque. This fitting is suited for plumbing, HVAC refrigerant-free fluid lines, and light pneumatic tubing runs where speed and leak-free performance are required.

This fitting is commonly installed in residential and light commercial applications where copper, nylon, or polyethylene tubing must transition to a threaded male NPT connection. Typical uses include water supply lines, compressed-air distribution, and fluid-control systems in HVAC and plumbing service work. The push-to-connect design reduces installation time compared to traditional compression fittings, making it a practical choice for service technicians working in confined or hard-to-reach locations. Plumbers and HVAC technicians are the primary installers.

Key Features

• Push-to-connect engagement on both tube ports eliminates the need for soldering or compression sleeves
• 3/8-inch OD tube compatibility on both tube-side connections
• 3/8-inch male NPT thread for direct connection to standard threaded ports
• Brass construction provides corrosion resistance for water and air service
• 250 psi maximum working pressure rating
• 3/4-inch hex allows standard wrench installation without slippage

Compatibility

Designed as an OEM-style push-to-connect brass fitting for 3/8-inch OD tubing systems with 3/8-inch MNPT threaded ports in residential and light commercial plumbing and HVAC fluid-line applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable IPC and local mechanical codes. Shut off and depressurize the line completely before removing or installing any fitting. Ensure tubing is cut square and deburred before inserting into the push-to-connect port to achieve a proper seal. Do not exceed the 250 psi rated working pressure; verify system pressure before returning the line to service.
