VIEGA reducing tee 22x22x15 mm, press fittings (model 5130)

VIEGA reducing tee 22x22x15 mm, press fittings (model 5130) is a press-fit branch connector designed to join three pipe sections where a reduced 15 mm outlet is required from a 22 mm run. Manufactured for use in metal and compatible press-fit piping systems, this reducing tee creates a durable, leak-resistant junction when installed with the appropriate press tools and jaws. It is intended for potable water, heating and general plumbing applications that require a reliable reduction in pipe diameter inline.

Advantages

The press-fit design delivers consistent, reproducible joints without soldering or threaded connections, reducing installation time and eliminating the need for open flames. High-quality materials and precision manufacturing ensure dimensional accuracy and long-term tightness under normal operating conditions. The reducing tee supports integrated system flow management by providing a secure 15 mm branch from a 22 mm main, compatible with standard press tools and fittings used in modern plumbing practice.

Suitable for

• Potable cold and hot water distribution
• Domestic and commercial heating systems
• Branching supply lines in sanitary installations
• Retrofit and new-build plumbing projects requiring a 22→15 mm reduction

Key specifications

• Connection type: press-fit on all three ends
• Pipe dimensions: main run 22 mm × 22 mm, branch 15 mm
• Material: corrosion-resistant metal alloy suitable for press systems
• Application media: potable water and heating fluids
• Installation method: mechanical pressing with compatible press tools and jaws

How to use

Select the correct press jaw and tool compatible with the fitting and pipe material. Ensure pipe ends are cut square, deburred and cleaned before insertion. Insert the pipe fully into each press socket until it reaches the stop. Position the press jaw over the fitting’s designated press profile and actuate the tool until the press cycle completes and an audible or visual confirmation is given, according to the tool manufacturer’s instructions. Verify the made joint and perform pressure testing of the system as specified by local regulations and project requirements.

Usage recommendations

Use only press tools and jaws recommended for VIEGA press fittings and observe manufacturer guidelines for pipe preparation and pressing depth. Do not use damaged or deformed fittings. After installation, carry out pressure testing and inspect joints visually. For systems carrying potable water, follow applicable drinking water installation standards and flush the system before use.
