Parker PP4FC4 Push-to-connect Fitting 1/4 in Od Nptf

Product Description

The PARKER PP4FC4 is a push-to-connect tube-to-pipe connector fitting designed for fast, tool-free tube connections in fluid and air distribution systems. Rated to 150 psi, this fitting accepts 1/4-inch OD tubing and connects to a 1/4-inch NPTF threaded port. The body is molded from polypropylene, making it suitable for water and many chemical media in low-pressure plumbing and instrumentation applications. The push-to-connect mechanism allows tubing to seat and seal without ferrules, compression nuts, or wrenches. Plumbers, HVAC technicians, and industrial service professionals install this fitting where a quick, reliable tube-to-pipe transition is needed in tight spaces or high-volume installations.

This fitting is suited for residential and light commercial plumbing, water treatment, pneumatic control circuits, and fluid handling systems that operate within the 150 psi pressure rating. The NPTF thread type creates a pressure-tight mechanical seal on the pipe side. The tan polypropylene construction is lightweight and corrosion-resistant, making it a common choice in water purification, ice maker supply lines, HVAC condensate management, and similar low-pressure applications where metal fittings are not required.

Key Features

• Push-to-connect design allows tool-free tube insertion for fast installation
• 1/4-inch OD tube connection on the push-connect end
• 1/4-inch NPTF threaded pipe connection for a pressure-tight seal
• 150 psi maximum pressure rating
• Polypropylene body offers corrosion resistance and chemical compatibility with many water and fluid media
• Tan color for easy visual identification in multi-line installations

Compatibility

Designed as an OEM-style push-to-connect fitting for use with 1/4-inch OD tubing and 1/4-inch NPTF threaded ports in low-pressure fluid and pneumatic systems.

Installation Notes

Ensure the tubing end is cut cleanly and squarely before insertion to achieve a proper seal. Shut off system pressure and depressurize the line before installing or removing push-to-connect fittings. Apply thread sealant appropriate for NPTF connections on the pipe-side thread as needed per local plumbing code. Do not exceed the 150 psi pressure rating or install in systems with fluids or temperatures incompatible with polypropylene.
