Parker PP4MES2 Male Swivel Elbow 1/4 in Od 1/8 in Nptf

Product Description

The PARKER PP4MES2 is a push-to-connect male swivel elbow tube fitting designed to transition from tubing to threaded pipe connections at a 90-degree angle. Constructed from white polypropylene, this fitting accepts 1/4 inch OD tubing on the push-to-connect end and threads onto a 1/8 inch NPTF male fitting on the pipe end. The swivel design allows the tube end to rotate after assembly, simplifying alignment in tight installations. Rated to 150 psi, it suits fluid and pneumatic lines in light-duty applications. Plumbers, HVAC technicians, and instrumentation installers use this fitting to route small-bore tubing to threaded ports on equipment, valves, or manifolds.

This fitting is suited for residential and light commercial applications involving small-diameter tubing runs connected to threaded pipe ports. Common install scenarios include condensate drain lines, water treatment equipment, pneumatic control lines, and fluid transfer systems where a directional change and thread transition are needed in a single fitting. The push-to-connect end simplifies tubing insertion without tools, reducing assembly time in multi-connection plumbing or instrumentation panels.

Key Features

• Push-to-connect end accepts 1/4 inch OD tubing without tools for fast, secure insertion
• Male NPTF thread on pipe end provides a pressure-rated, leak-resistant connection
• Swivel design allows tube end rotation after assembly for easier alignment
• Polypropylene construction resists corrosion and is compatible with a range of mild fluids
• Rated to 150 psi for light-duty fluid and pneumatic service
• Compact elbow form factor redirects tubing 90 degrees in minimal space

Compatibility

Designed as an OEM-style push-to-connect fitting for systems using 1/4 inch OD tubing with 1/8 inch NPTF threaded ports in light-duty fluid or pneumatic applications.

Installation Notes

Installation is performed by plumbers or HVAC technicians working on low-pressure fluid or pneumatic lines. Shut off system pressure and depressurize the line before disconnecting or installing any push-to-connect fitting. Insert tubing fully into the collet until it seats, and verify a firm connection with a gentle pull-back test. NPTF threads are self-sealing by design, but inspect the connection for leaks after restoring pressure in accordance with applicable codes.
