Parker PP4MES6 Male Swivel Elbow 1/4 in Od 3/8 in Nptf

Product Description

The PARKER PP4MES6 is a push-to-connect male swivel elbow tube fitting designed to transition between tubing and threaded pipe connections at a 90-degree angle. Constructed from white polypropylene, this fitting accepts 1/4 inch OD tubing and connects to a 3/8 inch NPTF male thread. It is rated to 150 psi and provides a secure, tool-free tube insertion on the push-to-connect end. The swivel feature on the threaded end simplifies alignment during installation. This fitting is suited for pneumatic tubing systems, fluid handling lines, and instrumentation plumbing in light industrial, HVAC, and commercial trade applications.

This fitting is installed in systems where a push-to-connect tube line must transition to a fixed threaded port at a right angle. Common applications include compressed air distribution, water and fluid control tubing, and instrument lines. The 90-degree elbow orientation is used where straight inline fittings cannot accommodate routing constraints. It is appropriate for both residential mechanical systems and light commercial environments where polypropylene construction is compatible with the media being conveyed.

Key Features

• Push-to-connect design allows tool-free tube insertion for 1/4 inch OD tubing
• Swivel male thread end simplifies alignment to 3/8 inch NPTF ports
• Polypropylene construction offers resistance to corrosion and many common fluids
• Rated to 150 psi for use in low-to-moderate pressure pneumatic and fluid systems
• 90-degree elbow geometry suits tight routing and directional changes
• NPTF thread type provides a pressure-tight mechanical seal

Compatibility

Designed as an OEM-style push-to-connect fitting for systems using 1/4 inch OD tubing and 3/8 inch NPTF threaded ports in pneumatic, fluid handling, and instrumentation applications.

Installation Notes

This fitting is typically installed by plumbers, HVAC technicians, or instrumentation mechanics working on low-pressure fluid or air lines. Shut off system pressure and depressurize the line before removing or installing any push-to-connect fittings. Ensure the tube end is cut cleanly and squarely and that tubing OD is within specification before insertion. Thread the NPTF male end into the port by hand first, then tighten to achieve a leak-free seal without overtightening polypropylene components.
