Parker B33-787 Pneumatic Hose Coupler 1/4 in Brass

Product Description

The PARKER B33-787 is a brass pneumatic hose coupler designed for industrial compressed air and pneumatic tool applications. With a 0.25-inch body diameter and a 1/4-18 inch threaded connection, this coupler follows the Industrial Interchange standard, making it widely compatible with common pneumatic quick-connect systems found in shops, service bays, and light industrial environments. The all-brass construction provides corrosion resistance and durability under repeated connect-disconnect cycles. HVAC technicians, plumbers, and general trade professionals who use pneumatic tools will recognize this as a standard coupler half used to mate hoses to tools, fittings, and manifolds.

This coupler is suited for residential and light commercial shop environments where Industrial Interchange-style pneumatic quick-connect fittings are the standard. It installs on compressed air hoses, blow guns, pneumatic wrenches, and similar tools. The threaded connection type allows it to be installed directly onto male-threaded ports or adapters. The compact body size makes it appropriate for 1/4-inch pneumatic line applications where space and weight are considerations.

Key Features

• Industrial Interchange coupler standard for broad compatibility with common pneumatic quick-connect systems
• Brass construction resists corrosion and handles repeated use in shop environments
• 0.25-inch body diameter suited for standard 1/4-inch pneumatic lines
• Threaded connection type for secure, leak-resistant installation on threaded ports
• 1/4-18 inch thread size matches common pneumatic hose and tool fittings

Compatibility

Designed as an OEM-style replacement or add-on coupler for Industrial Interchange-style pneumatic quick-connect systems using 1/4-inch body diameter fittings with 1/4-18 inch threaded connections.

Installation Notes

Installation is performed by any trade professional working with compressed air systems. Always depressurize the air line completely before removing or installing any pneumatic coupler. Use appropriate thread sealant or PTFE tape on the threaded connection to prevent air leaks. Do not overtighten brass fittings, as the material can be damaged by excessive torque applied with power tools.
