Parker H3F-G Female Nptf Pneumatic Connector 1/2 in

Product Description

The PARKER H3F-G is a female NPTF threaded pneumatic connector designed for Tru-Flate automotive-style pneumatic couplings. It features a 0.5-inch body diameter and is constructed from steel with a zinc chromate finish for corrosion resistance. This connector threads onto a 3/4-14 NPTF port and serves as the male-thread-receiving end of an air line connection. HVAC technicians, pneumatic tool operators, and general shop mechanics use this fitting to connect hoses, tools, or air supply lines in compressed-air systems. The threaded connection type ensures a secure, leak-resistant seal when properly torqued to a mating fitting.

The H3F-G is suited for automotive and light industrial pneumatic applications where Tru-Flate style couplers are the shop standard. It is commonly installed at compressor outlets, air drops, or inline along portable pneumatic hose assemblies. The zinc chromate finish helps resist corrosion in shop environments. This connector is sold individually and is appropriate for any application requiring a 3/4-14 NPTF female threaded inlet with a 0.5-inch coupler body.

Key Features

• 3/4-14 NPTF female threaded connection for secure, leak-resistant fit
• 0.5-inch body diameter compatible with Tru-Flate automotive-style pneumatic couplers
• Steel construction provides durability in shop and light industrial environments
• Zinc chromate finish resists corrosion from moisture and shop fluids
• Compact and lightweight at 0.26 pounds for easy inline installation

Compatibility

Designed as an OEM-style replacement or new-install connector for Tru-Flate automotive pneumatic coupling systems using 3/4-14 NPTF threaded ports and 0.5-inch body couplers.

Installation Notes

Installation is typically performed by a pneumatic technician or experienced mechanic. Depressurize and bleed the air line completely before disconnecting or installing any pneumatic fitting. Apply thread sealant or PTFE tape to the NPTF threads per shop practice and hand-tighten before final wrench tightening. Do not overtighten NPTF fittings, as the tapered thread form creates its own seal and excessive torque can crack the fitting body.
