Description

Overview

The 3/8 x 1/2 NPT hose barb connects flexible hose with a 3/8″ internal diameter to a female 1/2 NPT port. Its straight brass body combines a ribbed hose tail, installation hex and tapered male thread in one compact fitting. The larger threaded end allows a relatively small hose to connect directly into a larger port without adding a separate reducing adaptor.

Features

• 3/8″ hose barb sized to suit compatible hose by internal diameter
• 1/2 NPT male thread for a matching female threaded port
• Ribbed tail supports secure retention with a clamp or crimped ferrule
• Hex shoulder provides a proper tightening surface without gripping the barb

Compatibility and Fitment

Check the two connection sizes separately before ordering. The 3/8 measurement refers to the hose bore, while the 1/2 measurement refers to the nominal NPT thread. Reversing those sizes is the most likely selection error with this fitting. Also confirm that the receiving port is NPT rather than BSP because similar nominal sizes use different thread forms and should not be forced together.

Compliance and Safety

Depressurise and drain the circuit before removing or installing the fitting. Apply a compatible thread sealant to the male NPT thread, keeping excess material away from the internal passage. Cut the hose square, push it fully across the barbs and secure it with the retaining method specified for the hose. After assembly, restore pressure gradually and check both ends for leakage or movement.

Trailer Applications

The 3/8 x 1/2 NPT hose barb suits truck, trailer and workshop pneumatic systems where 3/8″ flexible hose terminates at a larger 1/2 NPT female port. Typical connection points may include valves, tanks, manifolds and other pneumatic equipment, provided the hose material, working pressure and conveyed medium suit the complete system.
