Parker 66PLP-4M-4G Push-to-connect Elbow Fitting 4mm

Product Description

The PARKER 66PLP-4M-4G is a push-to-connect tube-to-female elbow fitting designed for pneumatic and fluid-line applications where a 90-degree direction change is required. Constructed from nickel-plated brass with a silicone-free grease lubricant and a UL94 V-0 rated release button, this fitting accepts a 4mm outside diameter tube on one end and threads onto a female BSPP port on the other. It is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 200 degrees F. The push-to-connect mechanism allows fast, tool-free tube insertion, making it a practical choice for service technicians and installers working on compressed-air or pneumatic control lines.

This fitting is suited for residential and light commercial pneumatic systems, HVAC pneumatic controls, and instrumentation lines that run 4mm OD tubing. The BSPP female thread end connects directly to standard British Standard Parallel Pipe ported valves, manifolds, or equipment panels. The compact 1.52-inch overall length and 0.68-inch hex width make it usable in tight panel and cabinet installations. Technicians who need a reliable, leak-resistant elbow connection without ferrules or compression sleeves will find this fitting appropriate for both new installations and field repairs.

Key Features

• Push-to-connect design accepts 4mm OD tubing without tools or ferrules
• Nickel-plated brass construction for corrosion resistance and durability
• Rated to 300 psi maximum working pressure
• Operating temperature range of 0 degrees F to 200 degrees F
• UL94 V-0 flame-resistance rated release button with silicone-free grease
• BSPP female thread end for direct port connections to compatible pneumatic equipment

Compatibility

Designed for use with 4mm outside diameter tubing in pneumatic and fluid-line systems equipped with BSPP female-threaded ports. Consult system documentation to confirm thread type and tube OD before installation.

Installation Notes

Installation is performed by licensed HVAC technicians, instrumentation technicians, or qualified mechanical trades familiar with pneumatic systems. Depressurize and isolate the line completely before disconnecting or installing any fitting. Use an 11/16-inch hex wrench to torque the BSPP thread end to the port; do not over-tighten the threaded connection. To release the tube, depress the yellow release button fully while pulling the tube straight out.
