Eaton 2729 Pneumatic Hose Coupler 3/8 in Brass Nptf

Product Description

The EATON 2729 is a brass pneumatic hose coupler designed for compressed air and pneumatic tool lines in industrial and trade service environments. Built to the Industrial Interchange standard, it accepts a 3/8-18 NPTF thread and features a 3/8 inch body diameter. The NPTF thread form creates a pressure-tight mechanical seal without requiring additional sealant tape in most applications, reducing the chance of air leaks at the connection point. This coupler is installed by mechanical contractors, industrial maintenance technicians, and experienced trade professionals who maintain pneumatic tool circuits, air compressor distribution lines, and shop air systems.

The EATON 2729 is suited for general industrial pneumatic service wherever the Industrial Interchange coupler standard is specified. Industrial Interchange couplers are among the most widely used fitting types in North American shop air and pneumatic tool applications, making this coupler a practical fit for new installations and replacement work alike. The brass construction makes it appropriate for dry compressed air service. It is sold in a package quantity of two, which suits multi-port manifold work or paired replacement jobs.

Key Features

• Industrial Interchange standard — compatible with the most common North American pneumatic quick-connect ecosystem
• 3/8-18 NPTF thread provides a dry, pressure-tight seal at the connection
• 3/8 inch body diameter suits standard shop air and pneumatic tool line sizing
• Brass construction resists corrosion in dry compressed air service
• Sold as a pack of two for multi-point or paired replacement installs

Compatibility

Designed as an OEM-style replacement or new-installation coupler for pneumatic systems using the Industrial Interchange standard with 3/8-18 NPTF thread connections.

Installation Notes

Installation should be performed by a qualified mechanical or pneumatic technician. Depressurize the air line completely before removing any existing fitting or coupler. NPTF threads are designed to seal mechanically, but inspect threads for damage before assembly and apply thread sealant per shop practice if required. Do not overtighten brass fittings — hand-tight plus a controlled number of turns with a wrench is standard practice to avoid thread distortion.
