Parker 365PTC-4 Push-to-connect Union Elbow 1/4 in Od

Product Description

The PARKER 365PTC-4 is a push-to-connect union elbow tube fitting designed for tube-to-tube connections in fluid and pneumatic plumbing systems. Built from composite construction with a nitrile O-ring, this fitting accepts 1/4-inch OD tubing on both ends and delivers a rated working pressure of 250 psi. The push-to-connect mechanism allows fast, tool-free tube insertion, making it a practical choice for HVAC, refrigeration, and light pneumatic applications. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of fitting where a 90-degree directional change is needed between two tube runs without threaded connections.

The 365PTC-4 is suited for residential and light commercial applications where 1/4-inch OD tubing requires a clean elbow transition. Typical scenarios include control line plumbing, condensate or drain tubing routing, and pneumatic instrument lines where quick assembly and reliable sealing at up to 250 psi are required. The composite body keeps the fitting lightweight and resistant to corrosion, making it a common choice in environments where metal fittings may be subject to moisture or chemical exposure.

• 90-degree union elbow configuration for tube-to-tube directional changes
• Rated to 250 psi working pressure
• Composite body construction for corrosion resistance and light weight
• Nitrile O-ring provides reliable sealing across a broad range of fluids
• Accepts 1/4-inch OD tubing on both ports

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for systems using 1/4-inch OD tubing in fluid or pneumatic plumbing applications.

Installation Notes

Installation is performed by HVAC technicians, plumbers, or mechanical contractors working on tube-to-tube plumbing systems. Before servicing any line, depressurize and isolate the system to confirm zero pressure at the connection point. Ensure tubing ends are cut cleanly and squarely with no burrs before inserting into the push-to-connect ports, as irregular cuts can compromise the O-ring seal. Follow applicable mechanical codes and the fitting manufacturer guidelines for maximum pressure and compatible tubing materials.
