Norgren C00820400 Union Y Tube Fitting Brass 4mm

Product Description

The NORGREN C00820400 is a brass Union Y push-to-connect tube fitting designed to split or merge fluid or pneumatic lines in a single compact body. The fitting accepts tubes with a 4mm outside diameter on all three ports and holds a maximum working pressure of 150 psi. The nitrile O-ring construction provides a reliable seal across a temperature range of 0 to 175 degrees F. With an overall length of 37.10mm, this fitting installs quickly without tools, making it suitable for production lines, pneumatic control panels, and field service work where fast, secure connections are required. Plumbers, pipefitters, and pneumatic system technicians are the typical installers.

This Union Y fitting is used in pneumatic tubing systems where a single line must be branched into two outlets or two lines must be combined into one. The push-to-connect mechanism makes it well suited for instrument air circuits, process control tubing runs, and light industrial pneumatic assemblies where 4mm OD tubing is the standard line size. The brass body handles moderate-pressure service reliably across the full rated temperature range.

Key Features

• Push-to-connect design on all three ports — no tools or fittings required for tube insertion
• Brass body construction for corrosion resistance and durability in pneumatic and fluid service
• Rated to 150 psi maximum working pressure
• Nitrile O-ring seals rated from 0 to 175 degrees F
• Accepts 4mm OD tubing on all ports
• Compact 37.10mm overall length for use in tight panel and cabinet installations

Compatibility

Designed for use with 4mm outside diameter push-to-connect tubing in pneumatic and instrumentation systems requiring a Union Y configuration.

Installation Notes

Installation is performed by pneumatic system technicians or pipefitters. Depressurize and isolate the line completely before disconnecting or inserting any fitting. Ensure tube ends are cut cleanly and squarely with a tube cutter for a proper seal — a ragged or angled cut will compromise the O-ring seat. Do not exceed the rated working pressure of 150 psi or the maximum temperature of 175 degrees F.
