SANHA transitional nipple SANHA-Therm ZWxGZ 76.1 x 2½ for pipe connections

The SANHA transitional nipple SANHA-Therm ZWxGZ 76.1 x 2½ is a metal pipe fitting designed to join a 76.1 mm pipe end to a 2½-inch threaded connection. Manufactured for use in heating and plumbing systems, this transitional nipple enables a reliable change of diameter or connection standard between smooth pipe and threaded components. It is suitable for mechanical and hydronic piping installations where secure, pressure-resistant joints are required.

Advantages

This SANHA-Therm transitional nipple provides a compact solution for adapting pipe dimensions and joining different connection types without welding. The fitting is produced to industry-standard dimensions to ensure compatibility with common 76.1 mm pipework and 2½-inch threaded components. Its design focuses on a secure threaded interface and a smooth end suitable for soldering, brazing, or press-fit systems, facilitating flexible installation methods and reducing on-site adaptation time.

Suitable for

• Connecting 76.1 mm smooth pipe to 2½-inch threaded valves or fittings
• Retrofit and repair work in heating systems
• Hydronic piping installations and mechanical services
• Applications requiring a transition between metric pipe and inch-threaded components

Key specifications

• Connection 1: 76.1 mm pipe end (smooth)
• Connection 2: 2½-inch external/internal threaded connection
• Intended use: heating and plumbing systems, mechanical and hydronic piping
• Material: metal fitting suitable for standard plumbing joining methods
• Application: transitional fitting for diameter and connection standard changes

How to use

Prepare the 76.1 mm pipe end by cutting square and cleaning the surface according to the chosen joining method (e.g., soldering, brazing, or pressing). Apply the appropriate sealant or thread tape to the 2½-inch threaded connection if required by the installation standards. Insert or join the smooth end to the pipe following manufacturer guidelines for the selected technique, and tighten the threaded connection to the specified torque to ensure a leak-free joint. Verify alignment and pressure-test the assembly in accordance with system requirements.

Usage recommendations

Use compatible joining materials and follow local plumbing codes. Inspect threads and pipe ends for damage before installation and perform pressure testing after assembly. For applications involving high temperatures or aggressive media consult system specifications to confirm material suitability.
