Copper press fitting SANHA SANHA-Therm Kapa ZW 18, model 12430118, ø18 mm

SANHA-Therm Kapa ZW 18 is a copper press fitting for ø18 mm copper pipes designed for use in heating, plumbing and refrigeration installations. Manufactured by SANHA, the fitting is intended to create a permanent, mechanically secure and leak-tight joint when pressed with compatible press tools and jaws. The product is suitable for systems carrying potable water, heating circuits and refrigeration media where copper press technology is specified.

Advantages

The SANHA-Therm Kapa ZW 18 delivers a consistent press connection that reduces assembly time compared with soldering. Made of copper, the fitting offers good thermal and corrosion resistance in conventional heating and plumbing environments. Compatible with standard ø18 mm copper pipe dimensions and with widely used press systems, it ensures reproducible joins and long service life when installed according to manufacturer guidance.

Suitable for

• Domestic and commercial potable water supply lines
• Central heating and radiator circuits
• Refrigeration and air conditioning pipework where copper press fittings are specified

Key specifications

• Material: copper
• Connection method: press-fit (mechanical pressing)
• Pipe diameter compatibility: 18 mm (suitable for standard ø18 mm copper tube)
• Application media: potable water, heating media, compatible refrigeration fluids
• Operating environment: indoor plumbing, heating and refrigeration systems

How to use

Cut the ø18 mm copper pipe squarely and deburr the inner and outer edges. Slide the SANHA-Therm Kapa ZW 18 fitting onto the prepared tube end, ensuring full insertion to the stop. Position the appropriate press jaw on the fitting and perform the press operation with a compatible press tool following the tool manufacturer’s instructions. Verify the pressed joint visually and, where applicable, perform a pressure test according to system requirements and applicable standards.

Usage recommendations

Use only press tools and jaws that are approved for copper press fittings and sized for ø18 mm. Store fittings in a dry environment to avoid surface contamination. Do not use fittings that show visible damage or deformation. Follow local codes and standards for potable water, heating and refrigeration installations, and perform pressure testing after installation to confirm leak-tightness.
