Description

Overview

The 5/8 x 1/2 NPT hose barb connects flexible hose with a 5/8″ internal diameter to a female 1/2 NPT port. Its straight brass body combines a broad ribbed hose tail, installation hex and tapered male thread in one fitting. This pairing keeps the larger hose bore while providing a common threaded connection for pneumatic equipment.

Features

• 5/8″ hose tail suits flexible hose selected by internal diameter
• 1/2 NPT male thread connects to a matching female port
• Ribbed barb profile supports secure hose retention
• Central hex provides a controlled surface for installation

Compatibility and Fitment

Check the hose and thread measurements independently before ordering. The 5/8 x 1/2 NPT hose barb matches 5/8″ hose by internal diameter, not outside diameter, while the threaded end requires a female 1/2 NPT port. Do not substitute a BSP threaded fitting because the thread form and sealing method differ. Cut the hose square and confirm that it reaches the base of the barb without splitting or remaining loose.

Compliance and Safety

Depressurise and drain the circuit before removing or installing the fitting. Apply compatible thread sealant to the male NPT thread while keeping excess material away from the bore. Tighten the fitting through the hex rather than gripping the ribbed tail. Secure the hose with a clamp or crimped ferrule suited to its construction and operating pressure, then restore pressure gradually and inspect both connection points for leaks or hose movement.

Trailer Applications

This fitting suits compatible flexible hose runs on trucks, trailers, workshop air equipment and general machinery. The 5/8″ bore is useful where a larger hose must terminate at a 1/2 NPT valve, tank, manifold or accessory port. Confirm that the hose material, conveyed medium, temperature and working pressure suit the full system before installation.
