Midland Industries 10161SS Stainless Union Tee 3/8 in Flared

Product Description

The MIDLAND INDUSTRIES 10161SS is a stainless steel SAE 45-degree flare union tee designed for joining three hydraulic or refrigerant tubing lines at a single junction point. All three ports are 3/8 inch flared connections with a 5/8-18 thread, making this a symmetrical fitting that simplifies branch installations. Rated to 1000 psi and suitable for service temperatures from -65 to 250 degrees F, it is built for demanding fluid and gas system applications. Licensed plumbers, HVAC technicians, and hydraulic system installers work with this type of fitting in both new construction and service replacement scenarios.

This union tee is suited for residential and light commercial plumbing, HVAC refrigerant line work, and hydraulic tubing circuits where a three-way branch connection is required. It is compatible with aluminum, brass, copper, and steel hydraulic tubing per the manufacturer specification. The SAE 45-degree flare design provides a leak-resistant metal-to-metal seat without the need for thread sealant at the flare interface, which makes it a practical choice where clean, serviceable connections are a priority.

Key Features

• All three ports are 3/8 inch SAE 45-degree flared with 5/8-18 thread for consistent, symmetrical branch connections
• Stainless steel construction resists corrosion in wet, refrigerant, and hydraulic fluid environments
• Rated to 1000 psi working pressure for reliable performance in pressurized systems
• Operating temperature range of -65 to 250 degrees F covers most HVAC and hydraulic service conditions
• Center-to-end dimension of 1 x 0.44 inches supports compact installation in tight spaces
• Compatible with aluminum, brass, copper, and steel hydraulic tubing

Compatibility

Designed for use with aluminum, brass, copper, and steel hydraulic tubing with SAE 45-degree flare connections. Suitable as an OEM-style or replacement union tee in hydraulic and HVAC tubing systems requiring a 3/8 inch flared three-way junction.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or hydraulic systems technician following applicable codes. Depressurize and isolate the system completely before disassembling any flare fittings. SAE 45-degree flare connections rely on a metal-to-metal seat; inspect flare faces for nicks or deformation before assembly, and do not over-torque, as this can damage the flare seat and cause leaks. Confirm tubing material compatibility before installation.
