## Summary description

Sliding pipe coupling SANHA SANHA-THERM C-Stahl d18 (MPN 124270S18) for joining 18 mm steel pipes in heating and plumbing systems. Designed as a push-fit/connection element to allow axial movement and thermal expansion compensation. Suitable for use in domestic and commercial hydronic installations where a sliding coupling is required.

## Long description

The Pipe coupling (sliding) SANHA SANHA-THERM C-Stahl d18 is a mechanical connector designed to join 18 mm steel pipes in hydronic heating and plumbing systems. Built for installations where axial movement or thermal expansion must be accommodated, this sliding coupling provides a compact, push-fit style connection that preserves pipe alignment while allowing controlled longitudinal movement.
Advantages
This sliding coupling offers a space-saving design compatible with 18 mm steel pipe runs and supports thermal expansion without stressing adjacent fittings. The push-fit connection simplifies installation by reducing the need for soldering or threaded joints, and the construction is made to suit routine heating and plumbing use. The coupling maintains a sealed connection while permitting axial movement, which helps prevent pipe distortion and reduces stress on fixed anchors and fixtures.
Suitable for
 Joining 18 mm steel pipes in domestic or commercial hydronic heating systems
 Applications that require compensation for thermal expansion or contraction
 Sections of piping where limited axial movement is needed to protect fixed components
 Retrofit or replacement work where a compact, push-fit sliding connector is preferred
When it may not be suitable
This sliding coupling is intended for 18 mm steel pipes and may not be suitable for pipes of other materials or diameters without compatible adapters. It is not intended to replace flexible hoses or expansion joints in systems that require large movement amplitudes or vibration isolation beyond axial sliding.
Key specifications
 Pipe diameter compatibility: 18 mm
 Function: sliding (axial movement) coupling for thermal expansion compensation
 Application: hydronic heating and plumbing systems
 Connection type: push-fit style mechanical coupling
 Material family: steel coupling for steel piping systems
How to use
Prepare and deburr the ends of the steel pipes to ensure smooth insertion. Slide the coupling onto the pipe ends as specified by the manufacturer's fitment instructions, ensuring correct alignment and engagement depth for a sealed connection. After installation, check that the coupling can move axially as intended and that any pipe anchors or supports allow the required movement. Perform a pressure or leak test according to local codes and system requirements before putting the system into regular service.
What to consider before purchase
 Confirm the pipe outer diameter is 18 mm and that the pipes are compatible steel material
 Verify the required axial movement range and whether a sliding coupling meets system needs
 Ensure installation access and clearances are sufficient for push-fit assembly
 Check system pressure and temperature limits to confirm suitability for hydronic use
Usage recommendations
Use this sliding coupling in straight runs where limited axial compensation is needed; combine with appropriate fixed anchors and guides to control movement. Follow local installation standards and the manufacturer's assembly instructions to ensure a secure, leak-free connection.
