Parker KP23889 Push-to-connect Stem Adapter 1/4 Inch

Product Description

The PARKER KP23889 is a push-to-connect stem adapter tube fitting designed for quick, tool-free tube connections in pneumatic and fluid transfer systems. Constructed from nylon, this fitting accommodates 1/4 inch outside diameter tubing and is rated to 290 psi. The push-on design allows technicians to seat tubing with a single straight push, reducing installation time compared to compression or barb-style alternatives. This fitting is typically installed by HVAC technicians, plumbers, and general mechanical contractors working on compressed air lines, water lines, or light pneumatic control circuits.

This stem adapter is suited for residential and light commercial applications where nylon push-to-connect fittings are appropriate, including low-pressure pneumatic controls, tubing runs in HVAC equipment, and water supply lines within rated pressure limits. It is sold in a package quantity of five, making it practical for service vans and small-job restocking. Applications requiring higher pressure ratings or elevated temperatures should consult system specifications before use with nylon fittings.

Key Features

• Push-to-connect design allows tool-free tube insertion for fast field installation
• Nylon construction offers lightweight, corrosion-resistant performance in low-pressure service
• Rated to 290 psi for compatibility with a wide range of light pneumatic and fluid systems
• Accepts 1/4 inch OD tubing for a secure, consistent connection
• Packaged in quantities of five, convenient for stocking and multi-connection jobs

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4 inch OD push-to-connect tube connections rated within nylon fitting pressure and temperature limits.

Installation Notes

Installation should be performed by a qualified technician. Depressurize and isolate the tubing circuit completely before removing or installing any fittings. Ensure tubing is cut square with no burrs before inserting into the push-to-connect port to achieve a proper seal. Verify that system pressure and fluid compatibility are within the nylon fitting rating before returning the system to service.
