Norgren 120290600 Bulkhead Union 3/8 in Od M20x1.5

Product Description

The NORGREN 120290600 is a Pneufit straight bulkhead union push-to-connect tube fitting designed for tube-to-tube connections in pneumatic systems. Constructed from nickel-plated brass, it accepts 3/8 inch OD tubing and threads into bulkhead panels using an M20 x 1.5 thread. The fitting is rated for a maximum working pressure of 260 psi and carries a vacuum rating of 29.5 in-Hg, making it suitable for both pressure and vacuum pneumatic circuits. The overall installed length is 1.69 inches. HVAC technicians, pneumatic system technicians, and industrial maintenance professionals install this fitting where a tube line must pass through a panel or enclosure wall with a secure, leak-resistant connection.

This fitting is intended for general-purpose pneumatic applications across light industrial, commercial HVAC controls, and fluid handling systems. It is rated for operating temperatures from -4 degrees F to 175 degrees F, giving it a broad thermal range for indoor and light-duty industrial environments. The push-to-connect design allows fast, tool-free tube insertion while the bulkhead thread locks the fitting securely through panel walls up to the M20 x 1.5 thread engagement depth. Sold individually.

Key Features

• Push-to-connect tube retention requires no ferrules, compression nuts, or additional tooling for tube insertion
• Nickel-plated brass construction provides corrosion resistance in general-purpose pneumatic environments
• 260 psi maximum working pressure with 29.5 in-Hg vacuum rating supports both pressure and vacuum circuits
• M20 x 1.5 bulkhead thread mounts securely through panel walls or enclosures
• Wide operating temperature range of -4 degrees F to 175 degrees F suits varied service conditions
• Straight configuration with 1.69 inch overall length for low-profile panel installations

Compatibility

Designed for general-purpose pneumatic systems using 3/8 inch OD tubing where a bulkhead panel-mount union connection is required. No specific OEM system or model compatibility was stated in the available product data.

Installation Notes

This fitting is typically installed by pneumatic system technicians or qualified HVAC controls technicians. Depressurize and isolate the pneumatic circuit completely before removing or installing any fittings. Thread the bulkhead body through the panel cutout and secure with the provided locknut to the torque appropriate for the panel material, following the fitting manufacturer guidelines. Confirm tube OD is within specification and that the tube end is cleanly cut and deburred before insertion to ensure proper collet engagement and a leak-free seal.
