VIEGA stainless steel reducing tee 20 x 16 x 20 mm, corrosion-resistant, polished

The VIEGA stainless steel reducing tee 20 x 16 x 20 mm is a polished, corrosion-resistant pipe fitting designed to join three pipe runs where one branch has a smaller diameter. Manufactured from stainless steel with a hygienic metal surface, this reducing tee is intended for use in plumbing, potable water supply, and HVAC systems where durable, low-maintenance connections are required. Its polished finish supports cleanliness and reduces surface corrosion while providing reliable mechanical strength for standard piping installations.

Advantages

This reducing tee offers corrosion resistance inherent to stainless steel and a polished surface that is easy to clean and maintain. The precision dimensions ensure consistent fit and alignment with compatible 20 mm and 16 mm pipes, reducing installation time. The stainless construction provides long-term durability in wet and humid environments and is suitable for applications demanding hygienic materials. Its compact reducing design allows for smooth flow transition between differing pipe diameters.

Suitable for

• Potable water distribution systems
• Domestic and commercial heating systems (HVAC)
• Sanitary and hygiene-sensitive installations
• Plumbing repairs and new pipework where diameter reduction is required

Key specifications

• Material: stainless steel with polished finish
• Connection pattern: reducing tee with two equal 20 mm ends and one 16 mm branch
• Corrosion resistance suitable for wet environments
• Surface: hygienic, easy-to-clean polished metal
• Typical applications: potable water, heating and general plumbing

How to use

Ensure compatible pipe types and dimensions (20 mm and 16 mm) before installation. Prepare pipe ends by cutting square and deburring to ensure a flush fit. Slide the pipes into the tee until fully seated according to the chosen joining method (e.g., soldering, press-fit, or compression—follow the pipe and fitting system guidance). Verify alignment and secure connections following standard plumbing practice. After installation, perform a pressure test and inspect joints for leaks.

Usage recommendations

Use fittings and joining methods recommended for stainless steel piping systems; avoid dissimilar metals in direct contact without appropriate measures to prevent galvanic corrosion. For potable water and hygiene-critical systems, maintain the polished surface and inspect periodically for deposits. Follow local regulations and professional installation standards for pressure testing and system commissioning.
