Water meter connection fitting IMI TA 1½ x 1¼ red brass set with gaskets and check valve, category 2

The IMI TA connection fitting in red brass, size 1½ x 1¼, is supplied as a complete set including gaskets and an integrated check (non-return) valve, category 2. It is designed for reliable inlet and outlet connections to residential or commercial water meters, allowing leak-tight joints and providing backflow prevention. The fitting is suitable for potable water systems and for use during meter replacement or new installations where a compact connection component with a built-in non-return function is required.

Advantages

The red brass construction provides corrosion resistance and dimensional stability suitable for potable water installations. The set includes gaskets for immediate assembly and an integrated check valve that prevents backflow without requiring a separate valve body, simplifying installation and saving space. The compact design supports straightforward replacement of existing meter connections and reduces the number of joints, lowering the risk of leaks.

Suitable for

• Connection of residential water meters
• Connection of commercial water meters
• Meter replacement and retrofit projects
• New potable water installations requiring backflow prevention

Key specifications

• Material: red brass
• Connection size: 1½ x 1¼ (inlet x outlet)
• Included components: gaskets and integrated check (non-return) valve
• Application: potable water meter connections
• Valve category: category 2 non-return function

How to use

Shut off the water supply and relieve system pressure before beginning work. Remove the existing meter connection components if replacing an old fitting. Position the gaskets supplied in the set and assemble the fitting onto the meter inlet and outlet threads according to the pipe thread orientation. Tighten fittings to recommended torque values for the thread and material to ensure a leak-tight joint without deforming the gaskets. Verify correct orientation of the integrated check valve so it allows flow in the intended direction. After installation, slowly restore water supply and inspect all joints for leaks.

Usage recommendations

Use compatible thread sealants or torque settings recommended for red brass fittings and potable water applications. Periodically inspect the connection and check valve for signs of wear or leakage, especially after pressure events or maintenance. If system contaminants or hard water are present, consider scheduled inspection intervals to ensure continued reliable operation.
