Parker B38-7B Hose Barb Pneumatic Coupler 3/4 Inch Brass

Product Description

The PARKER B38-7B is a hose barb industrial pneumatic coupler designed for connecting pneumatic hose lines in compressed air systems. Built from brass, this coupler features a 3/4 inch body diameter and accepts 3/4 inch hose ID, making it a direct-fit solution for mid-to-large bore pneumatic lines. The barbed fitting style creates a secure mechanical grip on the hose, reducing the risk of blowoff under pressure. It is suited for use by industrial maintenance technicians, pipefitters, and pneumatic system installers working in shop, plant, or field environments.

This coupler is intended for use in industrial pneumatic systems where a reliable hose-to-line connection is needed at 3/4 inch hose diameter. Typical applications include compressed air distribution lines, pneumatic tool feeds, and general-purpose air supply connections in manufacturing and maintenance settings. The brass construction makes it appropriate for dry air service and moderate-pressure pneumatic circuits commonly found in industrial facilities.

Key Features

• Brass construction for durability and corrosion resistance in pneumatic air service
• 3/4 inch body diameter matches standard mid-bore industrial pneumatic hose lines
• 3/4 inch hose ID barb sizing for a secure mechanical grip on the hose
• Hose barb design eliminates the need for threaded hose ends at the connection point
• Industrial coupler-style body for use with compatible pneumatic quick-disconnect systems

Compatibility

Designed as an OEM-style replacement or direct-fit coupler for industrial pneumatic hose assemblies using 3/4 inch hose ID lines.

Installation Notes

Installation is typically performed by industrial maintenance technicians or pipefitters. Depressurize the entire pneumatic circuit and bleed residual air before disconnecting or installing any coupler. Insert the hose barb fully into the hose ID and secure with an appropriately rated clamp to prevent blowoff under operating pressure. Verify that the hose material and pressure rating are compatible with system operating conditions before placing the assembly back into service.
