SANHA SANHA-Therm transitional nipple 28 x 1¼, model 124243G28114

The SANHA SANHA-Therm transitional nipple 28 x 1¼ is a pipe fitting designed to join metric 28 mm tubing to a 1¼-inch threaded connection. Intended for heating and plumbing installations, this transitional nipple provides a reliable mechanical interface between press- or solder-connected piping and threaded components, enabling secure adaptation where differing pipe standards meet.

Advantages

This transitional nipple offers a compact, robust solution for mixed-dimension plumbing systems. Its construction is adapted for thermal and hydraulic applications, providing consistent sealing when installed according to recommended methods. The fitting simplifies system layout by eliminating the need for additional adapters and reduces assembly time when connecting 28 mm metric pipes to 1¼-inch threaded fittings.

Suitable for

• Connecting 28 mm metric copper or compatible tubing to 1¼-inch threaded valves and radiators
• Domestic and commercial heating systems where mixed-size connections are required
• Plumbing repairs and retrofits that convert press or solder joints to threaded components

Key specifications

• Connection types: 28 mm metric pipe to 1¼-inch threaded end
• Application: heating and general plumbing installations
• Function: mechanical transitional fitting between press/solder and threaded systems
• Typical materials: metal suitable for thermal and hydraulic use (see manufacturer material data)

How to use

Prepare the 28 mm pipe by cutting squarely and deburring the end. Install the fitting following the chosen connection method (pressing or soldering) on the metric side and tighten the threaded side into the mating 1¼-inch component using appropriate sealing tape or compound if required. Ensure alignment and support to avoid stress on the joint and follow applicable installation standards and local plumbing codes. Pressure-test the system after assembly to verify leak-free performance.

Usage recommendations

Use compatible pipe materials and tools recommended for 28 mm metric connections and 1¼-inch threaded fittings. Observe maximum operating pressures and temperatures specified by the system design and the fitting manufacturer. When in doubt, consult technical documentation or a qualified installer to confirm suitability for the intended application.
