Midland Industries 30279 Brass Swivel Connector 3/8 in

Product Description

The MIDLAND INDUSTRIES 30279 is a brass swivel connector designed to join a 3/8-inch push-on hose barb to a 3/8-inch male inverted flare fitting. The swivel action allows the hose end to rotate freely during installation, reducing hose twist and making tight-space connections more manageable. Rated to a maximum operating pressure of 150 psi, this fitting is built from brass for corrosion resistance in fuel, refrigerant, and hydraulic line applications. It measures 1.76 inches in length with a 0.62-inch hex for wrench engagement. Plumbers, HVAC technicians, and fleet service professionals will encounter this fitting in low-pressure fluid and gas line assemblies.

The 30279 is suited for residential and light commercial applications where a push-on hose must transition to an inverted flare male port. Common install scenarios include automotive fuel lines, LP gas appliance connections, and small-bore hydraulic or pneumatic circuits. The 5/8-18 thread specification matches standard inverted flare port sizing. This connector is well-suited for service work where hose orientation must be adjusted without stressing the line.

Key Features

• Swivel design allows free hose rotation, reducing installation stress and hose kinking
• 3/8-inch push-on hose barb end accepts compatible push-on hose without clamps
• 3/8-inch male inverted flare connection with 5/8-18 thread for standard port fitment
• Maximum operating pressure of 150 psi for low-pressure fluid and gas service
• Brass construction provides corrosion resistance and durability in wet or fuel-contact environments
• Compact 0.62-inch hex allows wrench access in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8-inch push-on hose barb to 3/8-inch male inverted flare connections rated at or below 150 psi.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic familiar with inverted flare fittings and push-on hose systems. Shut off and depressurize the line completely before removing or installing any fitting. Ensure the push-on hose is fully seated on the barb before pressurizing. Verify that the inverted flare port thread pitch matches 5/8-18 before applying any wrench torque to avoid cross-threading.
