SANHA reducing nipple SANHA-Therm ZWxZZ 76.1x54 for heating systems, copper/stainless connection

Reducing nipple SANHA-Therm ZWxZZ 76.1x54 is a pipe fitting designed for heating and plumbing systems that require a reliable reduction from 76.1 mm to 54 mm. Manufactured by SANHA for use in radiator and boiler circuits, the fitting has connection ends compatible with copper and stainless steel pipe systems and is suitable for press and jointing installation methods. The part is intended to maintain hydraulic continuity and pressure integrity where a stepped diameter change is necessary.

Advantages

The SANHA-Therm reducing nipple provides a precise dimensional transition between two pipe diameters, reducing the need for additional adapters. Constructed for compatibility with both copper and stainless connections, it supports commonly used press and mechanical joining technologies. The design minimizes flow disturbances at the reduction point and helps preserve system tightness under typical heating system pressures.

Suitable for

• Stepped reductions in radiator and boiler circuits
• Connections between copper and stainless steel pipework
• Press-fit and mechanical jointing applications in heating systems
• Replacement or retrofit in existing piping where diameter change is required

Key specifications

• Nominal sizes: 76.1 mm to 54 mm stepped reduction
• Application: heating and plumbing systems
• Material interfaces: compatible with copper and stainless pipe connections
• Suitable joining methods: press-fit and mechanical joints
• Intended use: radiator circuits, boiler circuits and associated hot-water distribution

How to use

Install the reducing nipple at the point where a transition from 76.1 mm to 54 mm pipe is required. Prepare pipe ends according to the chosen joining method: deburr and clean copper or stainless pipe ends for press-fit or mechanical joining. Position the fitting so that each end seats fully into the corresponding pipe diameter, then complete the connection following the press tool or jointing manufacturer's instructions. After installation, perform a pressure test in accordance with local regulations to verify system tightness.

Usage recommendations

Ensure compatibility of adjacent piping materials and confirm that the selected joining method is rated for the operating temperature and pressure of the heating system. Follow SANHA and tool manufacturer's guidelines for assembly and testing to maintain system reliability and safety.
