Parker 68PLPR-4-0 Push-to-connect Mnpt Fitting 1/4 in

Product Description

The PARKER 68PLPR-4-0 is a push-to-connect to male NPT tube fitting designed for quick, tool-free tubing connections in pneumatic and fluid-handling systems. Constructed from nickel-plated brass, it features a 10-32 male NPT thread on one end and accepts 1/4 inch OD tubing on the push-to-connect end. Rated to 300 psi maximum working pressure, this fitting is suited for moderate-pressure pneumatic lines. The release button is made from black flame-resistant material compliant with the UL94 V-0 standard. Plumbers, HVAC technicians, and industrial maintenance technicians install this fitting where a fast, reliable tube-to-threaded-port connection is required.

This fitting is used in residential and light commercial applications involving compressed air lines, pneumatic controls, and instrumentation tubing. It is a practical choice wherever a threaded port must accept push-in tubing without additional ferrules or compression hardware. The 10-32 thread size makes it compatible with small-port manifolds, solenoid valve bodies, and instrumentation fittings commonly found in HVAC control systems, pneumatic actuators, and similar equipment.

Key Features

• Push-to-connect end accepts 1/4 inch OD tubing for tool-free insertion and release
• 10-32 male NPT thread for direct port installation
• Nickel-plated brass construction for corrosion resistance in pneumatic service
• 300 psi maximum working pressure rating
• UL94 V-0 flame-resistant black release button material
• Compact profile at 0.96 inches height and 0.5 inches width

Compatibility

Designed as an OEM-style replacement push-to-connect fitting for pneumatic and fluid-handling systems requiring a 10-32 male NPT port connection with 1/4 inch OD tubing.

Installation Notes

This fitting is installed by plumbers, HVAC technicians, or pneumatic system technicians. Before installation, isolate and depressurize the system completely. Thread the male NPT end into the port by hand first, then tighten with an appropriate wrench to avoid cross-threading the small 10-32 thread. To insert tubing, push it firmly into the collet until it seats; to release, press the button collar and withdraw the tubing.
