Parker PP4MES4 Male Swivel Elbow Fitting 1/4 in Od

Product Description

The PARKER PP4MES4 is a push-to-connect male swivel elbow tube fitting designed for tube-to-pipe connections in fluid handling and pneumatic systems. Constructed from polypropylene in a white finish, this fitting accepts 1/4 inch OD tubing and transitions to a 1/4 inch NPTF male threaded port. The swivel design allows the threaded end to rotate during installation, reducing the need to manipulate connected tubing to achieve a proper thread engagement. Rated to 150 psi, it is suited for low-to-medium pressure plumbing, irrigation, water treatment, and light pneumatic applications where a corrosion-resistant fitting is required.

This fitting is commonly used in residential and light commercial plumbing, water filtration, reverse osmosis systems, and similar fluid distribution setups. The push-to-connect end provides a tool-free tube insertion that simplifies installation in tight spaces or manifold assemblies. Plumbers, HVAC technicians, and water treatment installers working with 1/4 inch OD tubing routes that must transition to NPT-threaded pipe ports will find this fitting applicable to a wide range of service calls and new installations.

Key Features

• Push-to-connect end accepts 1/4 inch OD tubing without tools for fast, secure connection
• Male swivel design allows the NPTF threaded end to rotate during thread-in, reducing tubing stress
• Polypropylene construction resists corrosion and is compatible with many water-based fluids
• Rated to 150 psi for low-to-medium pressure service
• NPTF thread type provides a pressure-tight mechanical seal without relying solely on thread sealant
• Compact elbow geometry redirects tubing runs at 90 degrees in space-constrained installations

Compatibility

Designed as an OEM-style push-to-connect fitting for use with 1/4 inch OD tubing and 1/4 inch NPTF male-threaded pipe ports in water treatment, filtration, and light pneumatic plumbing systems.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC and water treatment technicians. Shut off and depressurize the supply line before disconnecting or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect end, as irregular cuts can compromise the internal seal. Apply thread sealant or PTFE tape to the NPTF threads per local plumbing code requirements before engaging the threaded port.
