Midland Industries 57064-04 Brass Mini Barb Union Tee

Product Description

The MIDLAND INDUSTRIES 57064-04 is a single mini barb union tee fitting machined from brass. It connects three 1/4-inch hose barb lines at a single junction point, allowing one fluid or gas line to split into two, or two lines to merge into one. The fitting uses a barbed connection style on all three ports, creating a secure friction fit when tubing is pushed over each barb. Brass construction provides durability and resistance to corrosion in typical fluid and gas handling applications. This fitting is used by HVAC technicians, plumbers, and equipment service pros working on low-pressure tubing assemblies.

The 57064-04 is suited for residential and light commercial applications where small-diameter tubing must be branched or joined. Typical install scenarios include condensate drain lines, low-pressure pneumatic tubing, and secondary fluid circuits in HVAC and refrigeration equipment. All three ports accept 1/4-inch hose barb tubing, making this a symmetrical tee with no directional restriction on flow orientation. Its compact size makes it practical in tight equipment cabinets and confined service areas.

Key Features

• All three ports sized at 1/4 inch hose barb for symmetric tubing connections
• Mini barb profile provides a secure grip on flexible tubing without additional fasteners
• Brass construction resists corrosion in wet and humid service environments
• Compact union tee design fits in tight equipment enclosures
• Lightweight at 0.025 pounds, minimizing load on tubing assemblies

Compatibility

Designed as an OEM-style replacement or service fitting for low-pressure hose barb tubing assemblies using 1/4-inch flexible tubing.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or equipment service technicians. Shut off fluid or gas supply and relieve line pressure before removing or installing barb fittings. Push tubing fully onto each barb until it seats past the barb ridge, and secure with a hose clamp where required by the application or local code. Inspect tubing ends for cuts or deformation before assembly to ensure a leak-free seal.
