Parker 14C Pneumatic Hose Coupler 3/8 in Tru-flate Steel

Product Description

The PARKER 14C is a male NPTF threaded pneumatic hose coupler designed for compressed air tool connections in automotive and industrial service environments. Built from steel with a zinc chromate finish, this Series 10 coupler features a 3/8 inch body diameter and a 1/4-18 NPTF thread for a pressure-tight, leak-resistant connection. It handles a maximum working pressure of 300 psi and operates across a temperature range of -40 degrees F to 250 degrees F. HVAC technicians, auto service technicians, and industrial maintenance pros install this coupler when connecting air hoses to Tru-Flate Automotive interchange-compatible fittings.

The PARKER 14C is intended for compressed air hose and tool applications where the Tru-Flate Automotive interchange standard is required. Its threaded connection type makes it suitable for use in shop air systems, pneumatic tool setups, and general-purpose air line assemblies. The zinc chromate finish provides corrosion resistance in typical workshop and light industrial conditions. This coupler ships individually and is appropriate for both new installations and replacement of worn or damaged couplers in existing air systems.

Key Features

• Tru-Flate Automotive interchange type for broad compatibility with matching pneumatic fittings
• Male NPTF threaded connection at 1/4-18 for a pressure-tight seal
• 300 psi maximum working pressure rated for demanding shop air applications
• Wide operating temperature range: -40 degrees F to 250 degrees F
• Steel construction with zinc chromate finish for durability and corrosion resistance
• Compact overall length of 2.36 inches with a 0.88 inch hex for standard wrench installation

Compatibility

Designed as an OEM-style replacement or new-installation coupler for compressed air systems using the Tru-Flate Automotive interchange standard with 1/4-18 male NPTF threaded connections.

Installation Notes

Installation is performed by qualified mechanics or pneumatic system technicians. Depressurize and bleed down the air supply line completely before removing or installing any coupler. Use an appropriately sized open-end or box wrench on the 0.88 inch hex to tighten to a snug, leak-free fit without overtightening. Apply thread sealant compatible with compressed air systems to the NPTF threads per shop practice and applicable plumbing codes.
