## Long description

Compression coupling SANHA SANHA-NIROSAN-Stahl d 88.9 mm, model 6927089 is a mechanical connector designed for joining stainless steel and mixed-material pipework with a 88.9 mm nominal outer diameter. The coupling creates a compression seal without welding, offering a compact, serviceable connection that is suitable for repair work or new installations in plumbing, heating and industrial piping systems. The component is part of SANHA's range intended to provide secure, leak-resistant joints while allowing disassembly and maintenance when needed.
Advantages
The SANHA-NIROSAN compression coupling provides a robust, non-permanent mechanical joint that eliminates the need for hot-work methods such as welding or brazing. Its design ensures reliable sealing on stainless steel and mixed-material pipes, reduces installation time compared with welded connections, and enables future access for inspection or replacement. The compact form factor minimizes space requirements in confined installations and helps maintain line integrity under typical pressure and temperature conditions for plumbing and heating systems.
Suitable for
Joining stainless steel pipe sections with 88.9 mm outer diameter
Mixed-material pipe connections where mechanical compression is preferred
Plumbing systems including potable water lines where serviceable joints are required
Heating installations such as district heating, radiators, and hot water circuits
Industrial piping where a mechanically assembled, leak-resistant joint is needed for repair or modification
Key specifications
Nominal outer diameter: 88.9 mm
Type: compression coupling for mechanical pipe connection
Material compatibility: stainless steel and mixed-material piping systems
Connection method: non-welded mechanical compression
Design: compact, serviceable coupling suitable for disassembly and maintenance
How to use
Prepare pipe ends by ensuring they are clean, free from burrs and cut square. Slide the coupling components onto the pipe ends according to the manufacturer's assembly sequence, align the pipes to achieve the required insertion depth, and tighten the compression elements to the specified torque to form the seal. Follow SANHA installation instructions regarding lubrication, position of sealing elements and recommended tightening procedure. After assembly, inspect the joint visually and perform pressure testing as required by the system standards to confirm leak-tightness.
Usage recommendations
Use the compression coupling in installations that require a mechanical, serviceable joint and where welding is impractical or prohibited. Verify material compatibility, operating pressure and temperature limits for the system. Employ calibrated tools and follow SANHA's torque and assembly guidance to ensure reliable sealing and long-term performance.
