Parker 365PTC-6 Push-to-connect Tube Fitting 3/8 Inch Od

Product Description

The PARKER 365PTC-6 is a push-to-connect tube-to-tube fitting designed for fast, tool-free inline connections between two lengths of tubing with a 3/8 inch outside diameter. Built from composite material with a nitrile O-ring seal, this fitting delivers a rated working pressure of 250 psi. It is suited for pneumatic and fluid-transfer lines where quick assembly and reliable sealing are required. HVAC technicians, plumbers, and mechanical contractors install this type of fitting when splicing tubing runs or completing branch connections without threading or soldering.

This fitting is used in residential and light commercial applications where composite construction is acceptable for the fluid or gas being conveyed. Typical installations include pneumatic control lines, low-pressure fluid systems, and instrumentation tubing. The push-to-connect design allows field techs to make connections quickly during new installations or service calls without specialty tooling. The nitrile O-ring provides compatibility with a range of common system media.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure retention
• Rated for 250 psi working pressure
• Composite body construction for corrosion resistance in compatible media
• Nitrile O-ring seal for reliable low-leak performance
• Accepts 3/8 inch OD tubing on both ends for inline tube-to-tube connections

Compatibility

Designed as an OEM-style push-to-connect inline fitting for 3/8 inch OD tubing used in pneumatic, fluid-transfer, and mechanical systems requiring a composite-body connector rated to 250 psi.

Installation Notes

Installation is performed by trade mechanics, HVAC technicians, or plumbers working on low-pressure tubing systems. Before installing or replacing any inline fitting, depressurize and isolate the line completely. Ensure tubing ends are cut square and free of burrs before inserting into the fitting body to achieve a proper seal. Verify that the tubing material and system media are compatible with composite construction and nitrile O-rings before placing the fitting in service.
