Midland Industries 283X2 Brass Double End Union 1/8 in

Product Description

The MIDLAND INDUSTRIES 283X2 is a brass double end union fitting designed for split sleeve compression connections on both ends. It accepts 1/8-inch tubing on each side, joining two lines with a secure mechanical grip that requires no flaring or soldering. Rated to 150 psi and suitable for service across a temperature range of -40 to 220 degrees F, this fitting is built for reliable performance in pneumatic, instrumentation, and fluid transfer applications. The 5/16-24 thread specification provides consistent engagement with mating components. Brass construction resists corrosion in a wide range of media.

This union is used in residential and light commercial settings where a removable, reusable inline connection is needed between two runs of 1/8-inch tubing. Typical applications include instrument air lines, control tubing, and small-bore fluid systems where periodic disconnection for service or replacement is expected. It is well suited for HVAC control circuits, pneumatic actuator lines, and similar precision tubing assemblies where a leak-free, moderate-pressure union is required.

Key Features

• Split sleeve compression on both ends - no flaring or soldering required
• 1/8-inch connection size on each end for inline tubing joins
• 150 psi pressure rating for pneumatic and fluid service
• Operating temperature range of -40 to 220 degrees F
• 5/16-24 thread for consistent mating engagement
• Brass construction for corrosion resistance and durability

Compatibility

Designed as an OEM-style precision grip double end union for use with 1/8-inch OD tubing in compression fitting systems.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or instrumentation technician. Depressurize and isolate the tubing circuit completely before disassembly or installation. Hand-tighten the compression nuts to seat the split sleeve, then snug with a wrench - do not overtighten, as brass threads and sleeves can deform under excessive torque. Verify no leaks under system pressure before returning the line to service.
