SANHA reducing tee SANHA-Therm 3xZW 35x18x35 copper press fitting

The SANHA reducing tee SANHA-Therm 3xZW 35x18x35 copper press fitting provides a durable branch connection with a reduced bore for press piping systems. Manufactured from copper and designed for press installation, this reducing tee joins two 35 mm runs while supplying an 18 mm branch line. It is intended for use in heating and potable water systems where a smaller feeder or tap-off is required and is compatible with standard press tools and elastomeric seals suitable for SANHA-Therm fittings.

Advantages

This copper press fitting offers a compact, corrosion-resistant connection that maintains hydraulic performance while reducing installation time compared with soldered joints. The press design ensures a reliable, leak-tight joint when installed with appropriate press tools and seals. Its reduced bore branch allows system designers to downsize feeders without additional adapters, and the uniform copper construction supports thermal stability and long service life in typical heating and domestic water applications.

Suitable for

• Domestic hot and cold potable water distribution
• Central heating and radiator circuits
• Tapping off a main 35 mm run to feed smaller branches or appliances
• Renovation projects where press connections are preferred over soldering

Key specifications

• Material: copper
• Connection type: press fitting
• Configuration: reducing tee (two larger runs with smaller branch)
• Dimensions: main runs 35 mm, branch 18 mm
• Application: heating systems and potable water installations

How to use

Select compatible press tools and approved elastomeric seals for SANHA-Therm copper press fittings. Prepare pipe ends by cutting square and deburring the inside and outside surfaces. Insert pipes fully into the fitting until the stop is reached, verify correct alignment, and perform the press operation according to the tool manufacturer’s instructions. After pressing, visually inspect the press profile and, where applicable, perform a pressure test in line with installation standards to confirm joint integrity.

Usage recommendations

Use only seals and press jaws specified as compatible with SANHA-Therm copper press fittings. Avoid exposure to aggressive chemicals or atmospheres that may affect copper or sealing materials. Follow local codes and installation standards for potable water and heating systems, and conduct pressure testing after installation to ensure leak-free operation.
