Parker 68PLP-4M-2G Push-to-connect Male Connector 4mm

Product Description

The PARKER 68PLP-4M-2G is a straight push-to-connect male connector fitting designed for tube-to-male tube connections in compressed air, pneumatic, and fluid control systems. Constructed from nickel-plated brass with a silicone-free grease lubricant, this fitting accepts a 4mm outside diameter tube and connects to a 1/8 inch BSPP male thread. It is rated for a maximum working pressure of 300 psi and operates across a temperature range of 0 degrees F to 200 degrees F. The push-to-connect mechanism allows for tool-free tube insertion and a yellow release button for quick disconnection. Licensed HVAC technicians, plumbers, and pneumatic system installers working with metric tube sizes and BSPP-threaded ports will find this fitting suited to tight-clearance, inline connection points.

This fitting is intended for use in pneumatic control lines, instrumentation tubing, and fluid distribution systems where a compact straight male connector is required. The 4mm OD tube size and BSPP thread make it appropriate for metric-spec equipment common in commercial HVAC controls, refrigeration instrumentation, and industrial pneumatic panels. It is rated to UL94 V-0 flame resistance standards, making it suitable for installations with fire-rating requirements. The silicone-free grease is compatible with systems where silicone contamination is a concern, such as paint booths or precision instrumentation environments.

Compatibility

Designed as a straight push-to-connect male connector for 4mm OD tubing with 1/8 inch BSPP male thread ports, suitable for pneumatic and fluid control systems requiring metric tube connections.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid control systems. Depressurize and isolate the system completely before installing or removing any fittings. Ensure the tube end is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect collet. Verify that the thread type and tube OD of the mating components match this fitting before installation to prevent leaks or fitting damage.
