SANHA press reducing coupling 18x15 mm, SANHA PRESS SOLAR mufa redukcyjna

SANHA press reducing coupling 18x15 mm is a press-fit fitting designed for reliable connections between pipes of different diameters in plumbing, heating and solar systems. The SANHA PRESS SOLAR reducing coupling allows a smooth transition from 18 mm to 15 mm piping using the press-fit installation method, creating a mechanically secure and leak-tight joint without soldering or threading. The product is intended for use in potable water, central heating and solar circuit installations where a compact reduction fitting is required.

Advantages

The reducing coupling is made to be compatible with press systems, ensuring fast installation and consistent joint quality. Its construction provides a durable seal suitable for potable water and heating applications while minimising installation time compared with soldered or threaded connections. The compact design allows installation in confined spaces and integrates with common copper and press-compatible pipe materials used in modern installations.

Suitable for

• Reducing 18 mm pipe to 15 mm pipe runs in plumbing systems
• Central heating circuits that require a diameter transition
• Solar thermal system connections with press-fit technology
• Repairs and retrofits where soldering is impractical or undesired

Key specifications

• Connection type: press-fit reducing coupling
• Sizes: 18 mm to 15 mm
• Application: potable water, heating, solar circuits
• Material compatibility: press-compatible copper and compatible pipe systems
• Installation method: press tool required for permanent joint

How to use

Prepare the pipe ends by cutting square and removing any burrs or debris. Slide the press reducing coupling onto the prepared 18 mm and 15 mm pipe ends, ensuring full insertion to the stop. Use a compatible press tool and the appropriate jaw/profile for the fitting to execute a complete press cycle, creating the permanent mechanical and sealed joint. After pressing, visually inspect the joint and, where applicable, perform pressure testing according to local standards and project requirements.

Usage recommendations

Use the coupling only with press tools and jaws approved for the specific press system. Ensure selected pipe materials and wall thicknesses are compatible with press connections. Follow relevant plumbing and heating standards for installation, testing and commissioning of potable water, heating and solar systems to ensure safety and long-term performance.
