Description

Overview

The 1/4 NPT female cross joins four male threaded components at one compact pneumatic junction. Four equal female ports meet through the centre of the brass body, allowing air to enter or leave from any side where the system layout permits.

This four-way configuration provides one more connection than a female tee. It suits assemblies that need multiple valves, gauges, adaptors or air lines connected around a shared passage without stacking several separate fittings.

Features

• Four matching 1/4 NPT female threaded ports
• Cross-shaped body with ports arranged at 90 degrees
• Open central passage linking all four connections
• Solid brass construction with machined outer flats

Specifications and Materials

This No.37 fitting carries four equal 1/4 NPT female connections in a one-piece brass body. It accepts male threaded components directly and does not use tube nuts, olives or compression inserts.

Part number: 02N37-04.

For four-port connection details, see the manufacturer reference for a brass 1/4 NPT female cross

Compatibility and Fitment

Confirm that all four mating components use 1/4 NPT male threads. The most likely ordering errors are selecting a three-port female tee or matching the fitting to BSP threads by outside diameter alone.

Check the available space around every side of the body before assembly. Each connected component needs enough clearance for installation, and the cross should be supported while adjoining fittings are tightened.

Compliance and Safety

Depressurise the pneumatic system before removing or installing the cross. Clean each male thread and apply compatible pneumatic thread sealant without allowing excess material to enter the central passage.

Tighten each connection progressively so one side does not place twisting force through the body. Restore pressure gradually and leak-test all four joints before returning the system to service.

Trailer Applications

Trailer and heavy-vehicle workshops fit female crosses where several threaded pneumatic components need to share one compact junction. Typical service positions include control-air connections, gauge lines, valve assemblies and workshop air circuits using 1/4 NPT male fittings.

Why Choose ICS Trailers

Female crosses can be confused with tees or similar-looking BSP fittings. Compare the number of ports, nominal thread size and thread type with the removed fitting, or send clear photos and measurements if the connection needs further identification.
