Parker 17G Pneumatic Hose Coupler 1/2 in Tru-flate Female Nptf

Product Description

The PARKER 17G is a Tru-Flate style pneumatic hose coupler designed for automotive air tool and compressed air hose connections. Built from steel with a zinc chromate finish, this coupler features a 1/2 inch body diameter and a 3/4-14 female NPTF threaded inlet. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on thread sealant, making it a reliable choice for shop air systems operating under repeated connect and disconnect cycles. It is installed by HVAC technicians, automotive service professionals, and general shop maintenance personnel who work with compressed air distribution lines and pneumatic tooling.

This coupler is suited for automotive shop environments and light industrial compressed air systems where Tru-Flate interchange compatibility is required. The 3/4-14 NPTF female thread connects to standard pipe-threaded ports on manifolds, hose barb fittings, or inline regulators. The 1/2 inch body size supports airflow demands typical of impact wrenches, air ratchets, and blow guns. Its zinc chromate finish provides baseline corrosion resistance in shop environments exposed to moisture and oils.

Key Features

• Tru-Flate automotive interchange profile for broad coupler compatibility
• 3/4-14 female NPTF threaded connection for a pressure-tight mechanical seal
• 1/2 inch body diameter supports airflow for common pneumatic tools
• Steel construction for durability under repeated coupling cycles
• Zinc chromate finish for corrosion resistance in shop environments

Compatibility

Designed as an OEM-style replacement or direct-fit coupler for compressed air systems requiring Tru-Flate automotive interchange couplers with a 3/4-14 female NPTF threaded connection and 1/2 inch body diameter.

Installation Notes

Depressurize the compressed air line completely before removing or installing any coupler. Apply thread sealant tape or compound to the male NPTF threads as required by shop practice, though the NPTF thread form is designed for dry-seal engagement. Hand-tighten first, then wrench-tighten to avoid cross-threading the steel body. Inspect the coupler valve and sealing surfaces for wear or debris before returning the line to service.
