SANHA press reducing coupling 28 x 15 mm, model 162402815, female x female press fitting

SANHA press reducing coupling 28 x 15 mm is a female-to-female press fitting designed to join copper or other compatible metal pipes of differing diameters without soldering. The fitting creates a secure, leak-resistant connection when compressed with a compatible press tool and press jaws, enabling a transition from 28 mm to 15 mm pipe runs in potable water and heating systems. It is intended for use where space or installation speed requires a compact, mechanically pressed connection between two pipe sizes.

Advantages

The coupling provides a solder-free joint that reduces installation time and eliminates the need for open flames. Its press design ensures consistent pressure distribution around the pipe for a reliable seal and reduced risk of leaks. Made for compatibility with copper and similar metal tubes, the fitting supports potable water and heating applications and is suitable for both domestic and light commercial installations. The compact geometry simplifies retrofits and connections in confined spaces.

Suitable for (tasks / use cases)

• Reducing pipe diameter from 28 mm to 15 mm in potable water systems
• Transitions in central heating pipe runs
• Space-constrained installations and retrofits
• Areas where soldering is impractical or prohibited

Key specifications

• Connection type: female-to-female press fitting
• Material compatibility: copper and compatible metal pipes
• Size: 28 mm to 15 mm transition
• Application: potable water and heating systems
• Joining method: mechanical press connection using appropriate press tool and jaws

How to use

Ensure pipes are cut square, deburred and free of contaminants before assembly. Slide the fitting onto each pipe end so the pipe reaches the fitting’s internal stop. Use the correct press tool and matching jaw profile for the fitting material and dimensions, and perform a full press cycle according to the press tool manufacturer’s instructions. After pressing, inspect the joint visually and, where applicable, perform a pressure test in line with local regulations to confirm integrity before putting the system into service.

Usage recommendations

Use calibrated press tools and manufacturer-recommended jaw profiles to achieve the intended seal. Store fittings in a dry environment and protect ends from dirt prior to installation. Follow applicable plumbing codes and perform pressure testing after installation to verify leak-free operation.
