SANHA transitional nipple fitting SANHA-Therm Nypel ZWxGZ 28x1 for heating systems

The SANHA transitional nipple fitting SANHA-Therm Nypel ZWxGZ 28x1 for heating systems is a threaded transition component designed to connect different thread types or join dissimilar pipe materials within hydronic and heating installations. The specified size 28x1 denotes the nominal diameter and thread pitch used for secure mechanical and fluid connections in residential and light-commercial heating circuits, radiator connections, and boiler piping.

Advantages

This transitional nipple provides a compact and durable threaded connection that simplifies adaptation between components with different thread standards or pipe end preparations. Manufactured to meet industry requirements for heating systems, it offers reliable sealing when installed with appropriate sealing materials and torques. Its metal construction ensures mechanical strength and resistance to typical system pressures and temperatures encountered in heating applications.

Suitable for

• Connecting radiators to supply or return lines in residential heating systems
• Adapting between fittings with different thread types or sizes in boiler and hydronic circuits
• Repair or retrofit projects where existing pipework requires a threaded transition

Key specifications

• Designation: transitional nipple for heating systems
• Thread/size: 28x1 (nominal diameter and thread pitch)
• Function: threaded transition between different thread types or pipe materials
• Application: heating circuits, radiators, hydronic installations
• Material: metal suitable for heating use (see manufacturer data for exact alloy/finish)

How to use

Prepare the mating threads and pipe ends by cleaning and removing debris or old sealing compounds. Apply an appropriate thread sealant or tape compatible with heating systems to the male threads as recommended by system designers or local codes. Hand-start the nipple into the female thread, then tighten to the specified torque using appropriate tools to avoid over-stressing the threads or deforming connected components. After installation, pressure-test the circuit according to applicable regulations to verify leak-free connections before placing the system into regular operation.

Usage recommendations

Use thread sealants or tapes rated for hot water heating systems and follow the heating system manufacturer’s instructions and local plumbing codes. Avoid excessive tightening; if unsure, refer to torque recommendations for 28x1 threaded connections or consult a qualified installer. Inspect joints periodically for signs of leakage or corrosion, especially after initial heat-up cycles.
