Parker PP6MES4 Male Swivel Elbow Push-to-connect 3/8 Od

Product Description

The PARKER PP6MES4 is a push-to-connect male swivel elbow tube fitting designed to transition from a 3/8 inch OD tube to a 1/4 inch NPTF male threaded pipe connection. Constructed from white polypropylene, this fitting accepts tubing with a simple push-in connection while the swivel elbow body allows rotational adjustment to align with the mating port before final tightening. The fitting is rated to 150 psi and is suited for fluid transfer, pneumatic instrumentation, and plumbing distribution lines where a 90-degree directional change is required. Licensed plumbers and HVAC technicians commonly install this type of fitting in low-pressure process, refrigeration drain, or potable water distribution applications.

This fitting is appropriate for residential and light commercial applications where 3/8 inch OD tubing must terminate at a 1/4 inch NPTF male port. Typical install scenarios include condensate drain lines, water treatment distribution manifolds, ice maker supply lines, and similar low-pressure fluid circuits. The polypropylene body makes it suitable for water, mild chemicals, and non-reactive gases within its rated pressure and temperature limits. It is sold and packaged individually.

Key Features

• Push-to-connect design accepts 3/8 inch OD tubing without tools for fast, leak-free installation
• Swivel elbow body allows rotational alignment before locking the threaded end to the port
• 1/4 inch NPTF male thread provides a pressure-tight seal with tapered pipe thread fittings
• Polypropylene construction resists corrosion and is compatible with water and mild chemical media
• 150 psi pressure rating suitable for low-pressure plumbing and pneumatic instrumentation circuits
• White color finish for easy identification in multi-line installations

Compatibility

Designed as a direct-connect fitting for 3/8 inch OD tubing terminating at 1/4 inch NPTF male-threaded ports in low-pressure fluid and pneumatic systems. Verify that tubing material and media compatibility with polypropylene are confirmed before installation.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off and depressurize the system completely before disconnecting or installing any fitting. Insert tubing straight and fully into the push-to-connect collet to ensure the internal grab ring seats properly; partial insertion is a common cause of joint failure. Apply thread sealant tape or compound to the NPTF male threads per IPC and local code requirements, and do not overtighten the swivel body against the mating port.
