Parker B34-5BP Push-lok Hose Barb Coupler 3/8 Inch

Product Description

The PARKER B34-5BP is a Push-Lok hose barb coupler designed for industrial and pneumatic hose assemblies. The brass body measures 3/8 inch in diameter and accepts 3/8 inch inside-diameter hose, making it a direct-fit component for compressed air and low-pressure fluid transfer lines. The Push-Lok design allows hose to seat firmly onto the barb without clamps under normal operating conditions, simplifying assembly in tight spaces. Licensed tradespeople and industrial maintenance technicians routinely use this fitting to terminate flexible hose runs on pneumatic tools, compressors, and general shop-air systems.

This coupler suits residential and light commercial pneumatic applications where 3/8 inch hose is the standard line size. Typical installations include shop-air distribution, pneumatic tool hookups, and low-pressure compressed-air branch lines. The brass construction resists corrosion in environments where moisture is present in the air supply, which is common downstream of compressor tanks that lack full drying capability. No compatibility with specific system models or part numbers was stated in the product data, so refer to Parker documentation for full application guidance.

Key Features

• Push-Lok barb design seats 3/8 inch ID hose without external clamps under rated conditions
• Brass body provides corrosion resistance in moist compressed-air environments
• 3/8 inch body diameter matches standard pneumatic hose and fitting series
• Compact profile fits confined installation spaces on tool manifolds and air lines
• Single-piece construction with no moving parts reduces failure points

Compatibility

Designed as an OEM-style replacement or new-install fitting for 3/8 inch ID Push-Lok compatible pneumatic and industrial hose assemblies.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and lock out the air supply before disconnecting or installing any hose fitting. Seat the hose fully onto the barb and verify retention before returning the line to service. Follow applicable OSHA and local compressed-air safety codes when working on pressurized systems.
