Parker W68PLP-4M-4R Push-to-connect Male Connector

Product Description

The PARKER W68PLP-4M-4R is a straight push-to-connect male connector fitting designed for tube-to-male tube connections in pneumatic and fluid control systems. Constructed from nickel-plated brass with a silicone-free grease lubricant and a UL94 V-0 flame-resistant release button, this fitting is rated to 300 psi maximum working pressure. It accepts a 4 mm outside diameter tube on the push-to-connect end and connects via a 1/4 inch BSPT male thread on the opposite end. The overall length is 1.07 inches. Licensed plumbers, pipefitters, and pneumatic system technicians install this type of fitting in instrumentation, compressed air, and light fluid-handling applications.

This connector suits residential and light commercial pneumatic systems, compressed air distribution lines, and instrumentation tubing runs where a fast, tool-free tube connection to a male-threaded port is required. Its 4 mm tube OD sizing and BSPT thread type make it appropriate for metric tube systems paired with British-standard threaded ports. Operating temperature range spans 0 degrees F to 200 degrees F, making it suitable for most indoor mechanical room environments.

Key Features

• Push-to-connect design allows tool-free tube insertion and release via yellow release button
• Nickel-plated brass construction resists corrosion in compressed air and light fluid service
• Rated to 300 psi maximum working pressure
• UL94 V-0 flame resistance standard on release button component
• Silicone-free grease lubricant — compatible with systems sensitive to silicone contamination
• Wide service temperature range: 0 degrees F to 200 degrees F

Compatibility

Designed for use with 4 mm outside diameter tubing on push-to-connect end and 1/4 inch BSPT male-threaded ports. Intended for pneumatic instrumentation and compressed air systems requiring metric tube connections at British-standard threaded ports.

Installation Notes

Installation is typically performed by licensed pipefitters, plumbers, or pneumatic system technicians. Depressurize and isolate the system fully before removing or installing any fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect port — burrs or angled cuts can compromise the internal seal and grip ring. BSPT threads are tapered and seal on the thread form; apply appropriate thread sealant per the system design and relevant local mechanical codes.
