Parker 139PLP-6M Push-to-connect Plug Fitting 6mm

Product Description

The PARKER 139PLP-6M is a straight push-to-connect plug fitting designed to cap off a 6mm outside diameter tube line in pneumatic and fluid systems. Constructed from nickel-plated brass, it handles working pressures up to 300 psi and operates across a temperature range of 0 degrees F to 200 degrees F. The fitting uses a plug-in connection type with a yellow release button for quick disconnection without tools. Its compact overall length of 0.92 inches makes it suitable for tight panel and manifold installations. Licensed technicians and industrial service professionals use this fitting to terminate or isolate tube runs during system maintenance or reconfiguration.

This fitting is suited for pneumatic control systems, fluid power circuits, and instrumentation tubing where a fast, reliable tube termination is needed. The 6mm tube OD size is common in metric pneumatic systems found in light manufacturing, HVAC controls, and automated equipment. The nickel-plated brass body resists corrosion in moderate-humidity environments. Silicone-free grease is used in the assembly, making it compatible with applications where silicone contamination is a concern. This fitting is sold and installed as a single unit, typically by pneumatic system technicians or mechanical contractors performing line-isolation work.

Key Features

• Push-to-connect plug-in design with yellow release button for tool-free tube insertion and removal
• Rated for 300 psi maximum working pressure
• Nickel-plated brass body for corrosion resistance and durability
• UL94 V-0 flame resistance rating on internal components
• Silicone-free grease — compatible with silicone-sensitive systems
• Compact 0.92-inch overall length for confined installation spaces

Compatibility

Designed as an OEM-style push-to-connect plug for metric pneumatic and fluid tubing with a 6mm outside diameter.

Installation Notes

Depressurize and isolate the tube line fully before inserting or removing this fitting. Ensure the tube end is cut cleanly and squarely — a ragged or angled cut will compromise the seal. Push the tube firmly into the fitting until it seats; to remove, press the yellow release button while pulling the tube straight out. Follow applicable pneumatic system codes and the equipment manufacturer's pressure ratings when integrating this fitting into a live circuit.
