Parker B30-3B Hose Barb Pneumatic Coupler 1/4 Inch

Product Description

The PARKER B30-3B is a hose barb industrial pneumatic coupler designed to create fast, secure connections in compressed air and pneumatic systems. Constructed from brass, this coupler offers reliable corrosion resistance in demanding shop and field environments. The 1/4 inch body diameter and 1/4 inch hose ID provide a direct fit for standard quarter-inch pneumatic hose assemblies. It is installed by licensed HVAC technicians, plumbers, and industrial maintenance professionals working on pneumatic tool lines, air compressor distribution systems, and similar low-to-medium pressure applications.

This coupler is suited for use in residential, commercial, and light industrial pneumatic setups where a hose barb style connection is required. The hose barb design allows the fitting to grip the inner wall of the hose securely, reducing the risk of blowoff under normal operating pressures. Typical installation scenarios include connecting flexible pneumatic hose to air tools, blow guns, and compressed air distribution manifolds.

Key Features

• Brass construction for corrosion resistance and durability in pneumatic environments
• 1/4 inch coupler body diameter matches standard quarter-inch pneumatic hose systems
• 1/4 inch hose ID barb provides a secure mechanical grip on the hose interior
• Industrial-grade coupler style rated for repeated connect and disconnect cycles
• Compact, lightweight design at 0.27 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or direct-fit coupler for standard 1/4 inch ID pneumatic hose assemblies used in industrial and commercial compressed air systems.

Installation Notes

Installation is typically performed by HVAC technicians, pipefitters, or industrial maintenance mechanics. Depressurize and lock out the compressed air system fully before removing or installing any pneumatic fittings. A hose clamp is recommended over the barb to secure the hose and prevent separation under pressure. Follow applicable OSHA and facility safety guidelines for compressed air system work.
