Parker W68PLP-5/32-4 Push-to-connect Male Connector

Product Description

The PARKER W68PLP-5/32-4 is a push-to-connect male connector fitting designed for tube-to-male NPT inline connections in pneumatic and fluid control systems. Constructed from nickel-plated brass with a nitrile O-ring, it accepts 5/32-inch OD tubing on each tube port and connects to a 1/4-inch NPTF male threaded port. Rated to 300 psi maximum working pressure and approved for service between 0 degrees F and 200 degrees F, this fitting suits a wide range of compressed air, instrumentation, and light fluid plumbing applications. Installation requires no tools on the tube side — tubing seats and locks by insertion. Licensed tradespeople and instrumentation technicians install these in panel builds, OEM assemblies, and field service work.

This fitting is suited for residential and light commercial HVAC, pneumatic controls, and instrumentation tubing runs where a push-to-connect tube end must transition to a threaded male NPT port. The compact 1.03-inch overall length makes it practical in tight panel or enclosure environments. It is commonly found in control valve assemblies, pneumatic actuator supply lines, and compressed-air distribution manifolds. The NPTF thread form provides a pressure-tight metal-to-metal seal without relying solely on sealant tape.

Key Features

• Push-to-connect tube ports for tool-free tubing installation and removal
• Nickel-plated brass body resists corrosion in damp or moderate service environments
• NPTF thread provides a pressure-seating metal-to-metal seal at the male port
• Nitrile O-ring compatible with air, water, and many light hydraulic fluids
• UL94 V-0 flame-resistant black button material for added safety compliance
• 300 psi maximum working pressure with a service temperature range of 0 to 200 degrees F

Compatibility

Designed as an OEM-style push-to-connect male connector for pneumatic tubing systems using 5/32-inch OD tubing and 1/4-inch NPTF male threaded ports.

Installation Notes

Installation and service should be performed by a qualified technician familiar with pneumatic or fluid piping systems. Depressurize and de-energize the system completely before removing or installing any fitting. Ensure tubing is cut cleanly and squarely, with no burrs, before seating into the push-to-connect port; damaged tubing ends prevent a proper seal. Apply appropriate thread sealant to the NPTF threads per the system manufacturer and applicable plumbing code requirements before making up the threaded connection.
