Parker W68PLP-4M-2R Push-to-connect Male Connector 4mm

Product Description

The PARKER W68PLP-4M-2R is a straight push-to-connect male connector fitting designed for tube-to-male tube connections in pneumatic and fluid control systems. It accepts a 4mm outside diameter tube on the push-to-connect end and threads into a 1/8 inch BSPT male port on the equipment side. Constructed from nickel-plated brass, it carries a maximum working pressure of 300 psi and operates across a temperature range of 0 degrees F to 200 degrees F. The silver body with yellow release button makes tube insertion and removal straightforward during system assembly or maintenance. Licensed plumbers, HVAC technicians, and pneumatic system technicians are the primary installers of this fitting.

This fitting is suited for residential and light commercial applications where small-bore pneumatic or fluid lines connect to threaded male ports. Typical install scenarios include compressed air distribution panels, pneumatic control systems, and instrumentation plumbing where a compact, straight inline connection is needed between a 4mm OD tube and a BSPT-threaded component. The UL94 V-0 flame resistance rating and silicone-free grease make it appropriate for environments sensitive to ignition sources or silicone contamination.

Key Features

• Push-to-connect design allows tool-free tube insertion and single-finger release via yellow release button
• Nickel-plated brass construction provides corrosion resistance in moderate-duty pneumatic and fluid applications
• Rated to 300 psi maximum working pressure
• Operates from 0 degrees F to 200 degrees F
• UL94 V-0 flame resistance standard compliance
• Silicone-free grease — safe for silicone-sensitive environments

Compatibility

Designed for use with 4mm outside diameter tubing connecting to 1/8 inch BSPT male-threaded ports. Suitable as an OEM-style replacement or new-installation fitting in pneumatic and fluid control systems using BSPT thread standards.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid plumbing systems. Depressurize and isolate the system completely before removing or installing any fittings. Verify that the mating port carries a 1/8 inch BSPT thread profile before installation, as BSPT is not interchangeable with NPT without appropriate adapters. Confirm tube outside diameter is 4mm and that cut ends are clean and square to ensure a proper seal at the push-to-connect collet.
