Parker 165PLP-4 Union Elbow Fitting 1/4 in Od 300 Psi

Product Description

The PARKER 165PLP-4 is a push-to-connect union elbow tube fitting designed for tube-to-tube connections in fluid and pneumatic systems. Constructed from nickel-plated brass with a nitrile O-ring, it delivers a rated maximum working pressure of 300 psi across a temperature range of 0 to 200 degrees F. The push-to-connect design allows for fast, tool-free tube insertion, making it a practical choice for technicians working on HVAC, refrigeration, instrumentation, or general pneumatic plumbing lines where a 90-degree directional change is required.

This fitting is suited for residential and light commercial applications where 1/4 inch OD tubing must be routed at a right angle without soldering, flaring, or compression tooling. The black release button is made from flame-resistant material that meets the UL 94 V-0 standard, making it appropriate for installations where flame-resistance compliance is a requirement. HVAC technicians, plumbers, and instrumentation specialists commonly use this fitting in copper, nylon, or polyurethane tubing runs.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• Nickel-plated brass body for corrosion resistance and durability
• Rated to 300 psi maximum working pressure
• Operating temperature range of 0 to 200 degrees F
• Nitrile O-ring provides a reliable seal on compatible tubing materials
• Black release button meets UL 94 V-0 flame-resistant material standard

Compatibility

Designed for use with 1/4 inch OD tubing in tube-to-tube push-to-connect applications. Compatible tubing materials typically include copper, nylon, polyurethane, and similar semi-rigid or rigid tubing with a 1/4 inch outside diameter.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified instrumentation technicians. Before servicing any line, depressurize the system completely and verify pressure has been relieved before inserting or removing the fitting. Ensure tubing ends are cut cleanly and squarely with no burrs to achieve a proper seal. To release tubing, depress the collar button fully while pulling the tube straight out.
