Parker 15C Pneumatic Hose Coupler 3/8 in Tru-flate 300 Psi

Product Description

The PARKER 15C is a female-threaded pneumatic hose coupler designed for use in compressed air systems requiring a reliable, leak-resistant connection. Built to Tru-Flate Automotive interchange standards, this coupler features a 3/8-inch body diameter and a 1/4-18 NPTF female thread for secure, pressure-rated attachment. Constructed from steel with a zinc chromate finish for corrosion resistance, the 15C handles working pressures up to 300 psi and operating temperatures ranging from -40 degrees F to 250 degrees F. Licensed HVAC technicians, plumbers, and industrial mechanics rely on this style of coupler to connect air tools, hoses, and pneumatic control lines quickly and securely.

The PARKER 15C is suited for automotive service shops, light industrial facilities, and mechanical rooms where Tru-Flate Automotive interchange-style couplings are the shop standard. Its 3/8-inch body size and threaded connection make it a common fit for air hose assemblies, blow guns, impact wrenches, and other pneumatic tools operating on standard shop-air systems. The zinc chromate finish provides added durability in environments with mild moisture exposure. This coupler is sold individually and is compatible with standard Tru-Flate Automotive interchange series quick-connect air fittings.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with pneumatic systems. Depressurize the air line completely before removing or installing any coupling. Apply thread sealant or PTFE tape to NPTF threads as required by shop practice and applicable codes. Avoid over-tightening, which can distort threads and compromise the seal.
