Description

Overview

The NPT reducing hex nipple joins a 3/4 NPT female port to a 1/2 NPT female port through a straight male-to-male connection. Its unequal brass body steps the connection down between two pipe sizes, while the central hex provides a positive surface for controlled installation and removal.

Features

• 3/4 NPT male to 1/2 NPT male connection
• Straight unequal nipple configuration
• Brass body for pneumatic fitting applications
• Central hex section for spanner or socket access

Specifications and Materials

This reducing hex nipple carries a 3/4 NPT male thread at the larger end and a 1/2 NPT male thread at the smaller end. The open internal passage allows air to flow between the connected components. Material: brass. Part number: 02N73-1208.

See the manufacturer hex reducer nipple specifications

Compatibility and Fitment

Confirm that both connecting ports are female NPT and require different thread sizes. The larger end connects to a 3/4 NPT port, while the smaller end connects to a 1/2 NPT port. Do not substitute this fitting for BSP, metric, straight-thread or male-to-female adaptors, even where the visible diameter appears similar.

Compliance and Safety

Depressurise the air system before removing or installing the fitting. Clean both female ports and apply a suitable pneumatic thread sealant to the male NPT threads without allowing sealant to enter the bore. Tighten through the central hex and avoid overtightening the brass body. Restore pressure and leak-test both connections after installation.

Trailer Applications

Truck and trailer workshops use this fitting where pneumatic valves, manifolds or other air system components have unequal female NPT ports. It also suits compatible workshop air equipment that requires a straight transition from a 3/4 NPT connection to a 1/2 NPT connection.

Why Choose ICS Trailers

ICS Trailers supplies brass NPT fittings for heavy vehicle, trailer and workshop pneumatic repairs. When replacing an unidentified nipple, compare both thread sizes, thread form, overall length and available spanner clearance. Photos and outside thread measurements can help separate NPT fittings from similar BSP or metric parts.
