Parker 3C-E Pneumatic Coupling 3/8-18 Nptf Tru-flate

Product Description

The PARKER 3C-E is a threaded pneumatic hose coupling connector designed for use in compressed air systems requiring Tru-Flate Automotive interchange compatibility. Built from steel with a zinc chromate finish, this connector features a 3/8-18 female NPTF threaded connection and a 1/4 inch body diameter. It is rated for a maximum working pressure of 300 psi and handles temperatures from -40 degrees F to 250 degrees F. The overall length is 1.5 inches and the hex size measures 0.81 inches. Installation is handled by HVAC technicians, industrial maintenance professionals, and pneumatic system specialists working on shop air lines, pneumatic tool hookups, and related compressed air distribution systems.

The PARKER 3C-E connector fits applications where Tru-Flate Automotive interchange couplings are required. This includes light-duty shop air setups, automotive service equipment, and general-purpose pneumatic tool connections in both commercial and light industrial environments. The female NPTF thread ensures a pressure-tight mechanical seal without additional sealant when mated to a compatible male fitting. Its compact body and standard hex size make it straightforward to install in tight spaces or on equipment with existing Tru-Flate-style quick-disconnect infrastructure.

Installation Notes

Shut off and bleed compressed air pressure from the line before removing or installing any pneumatic coupling. Female NPTF threads are designed for pressure-tight engagement, but inspect thread condition before installation. Use an appropriate open-end or combination wrench sized to the 0.81 inch hex. Follow applicable shop safety practices and local codes governing compressed air system maintenance.
