Copper press sliding coupling SANHA 16270S18, 18 mm, female x female

SANHA copper press sliding coupling 16270S18 is an 18 mm female-to-female press fitting engineered for joining copper pipes in plumbing and heating systems. The sliding body provides a degree of axial adjustment to accommodate slight misalignment and length changes due to thermal expansion, allowing a secure, solder-free connection using compatible press tools. The design ensures leak-resistant joints suitable for potable water and heating circuits where a mechanical press solution is preferred.

Advantages

The coupling offers a solder-free installation method that reduces installation time and eliminates the need for open flames. Its sliding (adjustable) body compensates for pipe movement and small alignment deviations, improving joint reliability in dynamic or thermally active systems. Constructed for copper piping, the fitting provides corrosion-resistant contact surfaces and is compatible with standard press jaws for copper press connections.

Suitable for

• Joining 18 mm copper pipes in domestic and commercial plumbing
• Heating system pipe connections where thermal expansion occurs
• Areas requiring fast, flame-free installation with press tools
• Repairs or retrofits where minor pipe misalignment must be accommodated

Key specifications

• Material: copper fitting body designed for copper pipe connections
• Connection type: female x female press connection for 18 mm pipe
• Adjustability: sliding (axial) coupling body to allow slight movement and alignment
• Application: suitable for potable water and heating circuits
• Installation method: compatible with mechanical press tools for copper press fittings

How to use

Prepare the copper pipes by cutting squarely and deburring the inner and outer edges. Slide the coupling onto the pipe ends, ensuring full insertion to the stop. Position the press tool and compatible press jaw centered over the coupling’s press area and perform the press operation according to the press tool manufacturer’s instructions. Verify the sliding allowance is sufficient for thermal movement and check the finished joint for proper compression and sealing before system commissioning.

Usage recommendations

Use press tools and jaws specified for copper press fittings and follow applicable local regulations for potable water and heating installations. Inspect pipes for cleanliness and correct dimensions before assembly. After pressing, perform pressure and leak tests as required by system standards.
