Copper coupling SANHA 5270 15 mm (compression fitting) MPN 1527015

Copper coupling SANHA 5270 15 mm is a straight compression fitting designed to join 15 mm copper pipes in plumbing and heating systems. Manufactured by SANHA, this coupling provides a compact mechanical joint that restores or extends continuous copper tube runs without soldering. Its design is intended for use in residential and commercial installations where a durable metal connection is required for potable water, central heating circuits, or repair work.

Advantages

The coupling offers a reliable mechanical connection that eliminates the need for heat-based joining methods, reducing installation time and minimizing fire risk. Constructed from copper, it ensures corrosion resistance and compatibility with standard 15 mm copper tubing. The compression-style joint is suitable for tight spaces and allows for straightforward disassembly when maintenance or replacement is required.

Suitable for

• Joining or repairing 15 mm copper water supply pipes
• Connections in domestic central heating systems using copper tubing
• Retrofit and maintenance work in confined or flame-sensitive environments
• Commercial plumbing installations requiring compact mechanical fittings

Key specifications

• Material: copper
• Fitting type: straight coupling (compression fitting)
• Nominal pipe size: 15 mm
• Connection method: mechanical compression joint
• Application: potable water and heating systems
• Suitable for use in residential and commercial installations

How to use

Ensure the copper pipe ends are cut square, deburred and cleaned prior to assembly. Slide the compression nut and olive (if supplied) onto the pipe, insert the pipe fully into the coupling body, and tighten the nut by hand before applying a final controlled tightening with a wrench to form the compression seal. Do not overtighten; follow common compression fitting torque practices and any installer guidelines relevant to copper fittings. Verify the joint for leaks after pressurizing the system.

Usage recommendations

Use the coupling with correctly sized 15 mm copper tubing and inspect olives and nuts for damage before installation. When installing in systems carrying potable water or heating fluids, ensure compatibility with system pressure and local plumbing codes. For long-term reliability, avoid excessive mechanical stress on the joint and support adjacent pipe runs to prevent movement.
