VIEGA PRESTABO copper press tee 22x18x22 mm, model 558703

The VIEGA PRESTABO copper press tee 22x18x22 mm, model 558703 is a press-fit copper fitting designed to join three pipe runs where the branch connection is reduced to 18 mm between two 22 mm mains. Manufactured for use in potable water and heating systems, this copper press tee provides reliable metal body construction and compatibility with conventional press tools and jaws used for PRESTABO systems. The fitting is intended for creating secure, leak-resistant joints in systems where press connections are preferred for speed and consistency.

Advantages

The copper construction ensures corrosion resistance and mechanical strength appropriate for domestic hot and cold water distribution and heating circuits. Press-fit joining removes the need for soldering or threaded connections, reducing installation time and the risk of heat exposure. The reduced middle branch allows transition from a larger run to a smaller branch without additional adapters, simplifying system layout. The fitting is compatible with standard press connection processes for PRESTABO, offering predictable joint quality when installed with recommended tools.

Suitable for

• Domestic hot and cold potable water distribution
• Heating circuits and radiator connections
• Tight spaces where press connections speed installation
• Retrofitting and renovation projects requiring reduced-branch fittings

Key specifications

• Material: Copper
• Configuration: Tee with reduced middle branch
• Connection type: Press-fit compatible with PRESTABO press tools
• Dimensions: 22 mm × 18 mm × 22 mm (runs × branch × run)
• Application: Potable water and heating systems

How to use

Prepare pipe ends by cutting square and removing burrs and debris. Slide the appropriate press jaws over the fitting and position the fitting onto the pipes, ensuring full insertion to the stop. Use a suitable PRESTABO-compatible press tool and the manufacturer-recommended jaws to make the press connection according to the tool instructions. Inspect each joint visually and, where required, perform a pressure test of the completed system following applicable standards and regulations.

Usage recommendations

Use only press tools and jaws approved for PRESTABO copper fittings, verify pipe compatibility and wall thickness before installation, and follow local codes for potable water and heating system commissioning and testing.
