Parker 68PLP-4-6G Push-to-connect Male Connector 1/4 Od

Product Description

The PARKER 68PLP-4-6G is a push-to-connect tube-to-male fitting configured as a straight male connector. It accepts 1/4-inch OD tubing on the push-to-connect end and connects to a 3/8-inch BSPP male thread on the opposite end. The body is nickel-plated brass with a silver finish, and the release button is made from black flame-resistant material rated to UL94 V-0. Rated to 300 psi maximum working pressure, this fitting handles operating temperatures from 0 degrees F to 200 degrees F. It is typically installed by plumbers, HVAC technicians, and industrial fluid-system mechanics working with compressed air, water, or compatible fluid lines.

This fitting is suited for residential, commercial, and light industrial applications where a secure, tool-free tube connection to a male-threaded port is required. The straight configuration allows direct in-line connection without bends or offsets. The push-to-connect design enables fast tube insertion and removal using the green release collar, reducing labor time on installations and service calls. It is commonly used in pneumatic control systems, HVAC equipment, and fluid distribution assemblies where BSPP-threaded ports are present.

Key Features

• Push-to-connect design accepts 1/4-inch OD tubing without tools
• 3/8-inch BSPP male thread for direct port connection
• Nickel-plated brass construction for corrosion resistance
• 300 psi maximum working pressure rating
• Operating temperature range: 0 degrees F to 200 degrees F
• UL94 V-0 flame-resistant release button material

Compatibility

Designed for use with 1/4-inch OD tubing in systems with 3/8-inch BSPP male-threaded ports. Verify thread type and tube OD before installation, as BSPP threads are not interchangeable with NPT or other thread standards.

Installation Notes

Shut off system pressure and depressurize the line completely before installing or removing this fitting. Ensure the tube end is cut cleanly and squarely with no burrs before inserting into the push-to-connect end. Thread engagement should follow BSPP sealing practices, which typically rely on a bonded seal or O-ring face seal rather than thread-form sealing. Do not overtighten the threaded connection or force tubing into the connector at working pressure.
