## Summary description

VIEGA stainless steel pipe tee 22 x 1/2" (MPN 558901) is a plumbing fitting for creating a branch in a pipeline. Made of stainless steel for corrosion resistance, it connects a 22 mm main line to a 1/2" branch, suitable for potable water, heating and general plumbing systems. Ideal for installers and repair work requiring reliable, durable joints.

## Long description

The VIEGA pipe tee 22 x 1/2" stainless steel is a press- and threaded plumbing fitting designed to create a branch connection between a 22 mm main line and a 1/2" secondary line. Constructed from corrosion-resistant stainless steel with EPDM sealing elements and press connections plus Rp-thread, this fitting is intended for potable water, heating and general plumbing systems where durable, leak-resistant joints are required. The design includes a polygon-shaped sealing interface and complies with typical installation workflows for modern press systems.
Advantages
This stainless steel tee offers corrosion resistance and mechanical strength typical of non-alloyed, galvanised steel components combined with reliable EPDM seals for leak protection. The combination of press connections and Rp-thread provides flexibility during installation and allows integration into both press-fit and threaded sections of a system. The product's geometry and sealing design reduce the risk of leaks when installed with the appropriate press tool and technique.
Suitable for
Creating branch connections from 22 mm supply lines to 1/2" fixtures or risers
Potable water distribution systems
Heating installations and radiators
General plumbing repair and renovation work where press fittings are used
When it may not be suitable
This fitting may not be suitable for systems that require non-metallic components or where weldable fittings are mandated. It is also not intended for use with fluids incompatible with EPDM sealing materials or for services requiring ratings beyond the mechanical or temperature limits of standard stainless steel press fittings. Verify compatibility with local regulations and system requirements before use.
Key specifications
Material: stainless steel (non-alloyed, galvanised finish)
Connection types: press connections and Rp-thread
Nominal dimensions: main line 22 mm; branch 1/2"
Sealing: EPDM sealing elements with polygon interface
Suitable media: potable water, heating fluids
How to use
Prepare the pipe ends by cutting square and deburring. Insert the pipes fully into the press connections and position the fitting according to the manufacturer's press-marking guidance. Use the correct press tool and jaw for the fitting size to complete the press operation. For the threaded branch, apply appropriate thread sealant or tape where required and tighten to the specified torque. After installation, perform pressure testing in accordance with applicable standards to ensure leak-tightness.
What to consider before purchase
Confirm compatibility of EPDM seals with the system fluids and operating temperatures
Ensure available press tooling and correct jaw size for 22 mm press connections
Check that the Rp-threaded branch size matches connecting components
Verify local codes permit press-style stainless steel fittings in the intended application
Usage recommendations
Use certified press tools and follow VIEGA installation instructions. Perform pressure testing after installation and inspect seals for proper seating. For long-term reliability, avoid exposure to aggressive chemicals not compatible with stainless steel or EPDM.
