Parker 165PLP-4M Push-to-connect Union Elbow 4mm 300 Psi

Product Description

The PARKER 165PLP-4M is a push-to-connect tube-to-tube union elbow fitting designed for 90-degree direction changes in pneumatic and fluid tubing runs. Constructed from nickel-plated brass with a silver finish and yellow release button, it accepts tubing with a 4mm outside diameter and holds a maximum working pressure of 300 psi. The fitting requires no tools to connect — tubing inserts and locks instantly. It operates across a temperature range of 0 degrees F to 200 degrees F and meets the UL94 V-0 flame resistance standard. Silicone-free grease is used internally, making it compatible with applications where silicone contamination is a concern. HVAC technicians, plumbers, and instrumentation technicians install this fitting in compressed air, pneumatic control, and low-pressure fluid systems.

This fitting is suited for residential and light commercial applications where 4mm OD tubing requires a clean 90-degree turn without soldering, threading, or crimping. Typical install scenarios include condensate drain routing, pneumatic control line work, and instrumentation tubing assemblies. The push-to-connect mechanism allows for rapid assembly and field modification, which is useful in tight equipment enclosures or when reworking existing tubing layouts. The yellow release button permits tubing removal without cutting for system reconfiguration or service.

Key Features

• Push-to-connect design: no tools required for tube insertion or release
• Nickel-plated brass body provides corrosion resistance in damp or condensate-prone environments
• Rated to 300 psi maximum working pressure
• 4mm OD tube compatibility for metric tubing systems
• Silicone-free grease — safe for silicone-sensitive applications
• UL94 V-0 flame resistance rating
• Yellow release button allows tubing removal without cutting

Compatibility

Designed as an OEM-style push-to-connect union elbow for use with 4mm outside diameter tubing in pneumatic and low-pressure fluid systems.

Installation Notes

Depressurize and isolate the tubing circuit before connecting or disconnecting this fitting. Ensure tubing ends are cut cleanly and squarely with a proper tubing cutter — ragged cuts can compromise the seal and lead to leaks under pressure. Verify that the tubing outside diameter is within the 4mm specification before insertion; mismatched tubing will not seat correctly. Inspect the fitting body for damage before installation and confirm all connections are fully seated before returning the system to service.
