Copper press sliding coupling SANHA 16270S22 22 mm for press fittings

The Copper press sliding coupling SANHA 16270S22 22 mm for press fittings is a sliding coupling designed for use with press-fit copper piping systems. It provides a secure, solder-free connection while allowing axial movement to accommodate thermal expansion and contraction in plumbing and heating installations. The coupling is compatible with standard press tools and press fittings used for copper press systems, enabling reliable, leak-free joints without open flames.

Advantages

The sliding design permits controlled axial movement, reducing stress on joints caused by temperature variations and system settling. Press-connection technology eliminates the need for soldering, speeding up installation and improving safety on site. Constructed for compatibility with copper press fittings, the coupling ensures consistent mechanical and hydraulic performance when installed with approved press tools and seals.

Suitable for

• Domestic and commercial hot and cold water distribution
• Central heating systems and radiator connections
• Renovation projects where thermal movement compensation is required
• Installations requiring flame-free press fittings

Key specifications

• Material: copper press fitting compatible construction suitable for copper piping
• Connection method: press-fit sliding coupling for flame-free jointing
• Nominal diameter: 22 mm
• Function: axial movement/sliding to compensate thermal expansion
• Application: potable water and heating systems

How to use

Select compatible press tools and sealed press rings approved for copper press systems. Prepare pipe ends by cutting square and deburring to ensure a clean fit. Slide the coupling onto the pipe, allowing the sliding section to move as required for the application, then use the appropriate press tool to compress the coupling at the designated press zone until the press profile is complete. Verify the press connection visually and by test pressure in accordance with local regulations and manufacturer guidance.

Usage recommendations

Use only press tools, jaws and sealing elements specified for copper press systems. Allow sufficient room for axial movement when installing the sliding coupling, and perform pressure tests after installation to confirm leak-free operation. Do not solder on the press connection; if additional fixation is required, follow manufacturer instructions for mechanical supports.
