Parker TL-504-4MP Pneumatic Hose Coupling Nipple

Product Description

The PARKER TL-504-4MP is a pneumatic hose coupling nipple designed for use in compressed air and pneumatic fluid conveyance systems. Built from steel with a zinc chromate finish, this threaded nipple provides a secure, leak-resistant connection point in pneumatic lines. It accepts a 1/4-18 thread size and features a 0.5-inch coupler size. The zinc chromate finish offers corrosion resistance in light industrial environments. Licensed HVAC technicians, pipefitters, and maintenance mechanics typically install this type of fitting as part of pneumatic control or air supply infrastructure.

The TL-504-4MP suits residential and commercial applications where threaded pneumatic couplings are required. It is appropriate for use in compressed air distribution systems, pneumatic tool supply lines, and control system air circuits. The operating temperature range of -40 degrees F to 250 degrees F makes it suitable for a wide range of indoor and outdoor pneumatic service scenarios. This fitting is sold individually and is intended as a direct replacement or maintenance spare in existing pneumatic systems.
