Parker TL-254-4FP Pneumatic Coupling Nipple Schrader Twist-lock

Product Description

The PARKER TL-254-4FP is a pneumatic hose coupling nipple designed for use in compressed air and pneumatic systems. It features a Schrader Twist-Lock interchange design and accepts a 1/4-18 female NPTF threaded connection. The body diameter measures 1/4 inch with an overall length of 1.6 inches. Constructed from steel with a zinc chromate finish for corrosion resistance, this nipple is rated for a maximum working pressure of 300 psi and handles temperatures from -40 degrees F to 250 degrees F. Licensed HVAC technicians, plumbers, and industrial maintenance professionals use this type of fitting to make quick, secure pneumatic hose connections in tight service environments.

This coupling nipple is suited for residential and commercial pneumatic applications where Schrader Twist-Lock interchange compatibility is required. Typical install scenarios include compressed air distribution lines, pneumatic tool connections, and control system air supply lines. The female NPTF thread type ensures a pressure-tight mechanical seal without the need for additional sealant tape in many applications, though thread sealant practices should follow the governing job specification. The compact 1.6-inch overall length makes it practical in confined plumbing or equipment panels.

Compatibility

Designed as an OEM-style replacement nipple for pneumatic systems using Schrader Twist-Lock interchange couplings with 1/4-18 female NPTF threaded connections.

Installation Notes

Installation is typically performed by licensed pipefitters, HVAC technicians, or qualified maintenance mechanics. Shut off and bleed down all compressed air pressure in the line before removing or installing any pneumatic fitting. Inspect threads for damage before assembly and apply thread sealant or tape as required by the applicable job specification or local mechanical code. Do not exceed the rated working pressure of 300 psi.
