SANHA transitional tee NIROSAN stainless steel d42 × 1/2" GWSANHA

The SANHA transitional tee NIROSAN stainless steel d42 × 1/2" GWSANHA is a pipe fitting designed to join a stainless steel run with a smaller threaded branch. It allows connection between a d42 plain-end pipe and a 1/2" female threaded outlet, combining corrosion resistance of stainless steel with secure mechanical performance. The product is intended for plumbing, heating and potable water systems where a change in diameter and a threaded connection point are required.

Advantages

This transitional tee is manufactured from NIROSAN stainless steel, offering resistance to corrosion and long-term durability in wet environments. The combination of a smooth d42 connection and a 1/2" threaded branch provides flexibility during installation, enabling direct connection to threaded valves, meters or accessories. Its construction delivers mechanical strength suitable for pressurized systems and reduces the need for additional adaptors when mixing pipe sizes and thread fittings.

Suitable for

• Plumbing systems that require a step from d42 stainless pipe to a 1/2" threaded outlet
• Domestic and commercial heating installations
• Potable water distribution where corrosion-resistant materials are required
• Connections to threaded valves, gauges or service taps

When it may not be suitable

This transitional tee is intended for stainless steel piping and threaded 1/2" connections; it may not be suitable where different materials are required for galvanic isolation or where non-threaded branch connections are specified. It is not appropriate for applications that require specialized coatings, extremely high-temperature services beyond typical plumbing/heating ranges, or where a different branch diameter or thread type is needed.

Key specifications

• Material: NIROSAN stainless steel (corrosion-resistant stainless)
• Main run connection: d42 (plain or compatible stainless pipe end)
• Branch connection: 1/2" female threaded outlet
• Application: plumbing, heating, potable water systems
• Function: transitional tee for diameter change with threaded branch

How to use

Install the tee by preparing the d42 stainless steel run pipe according to the chosen joining method for NIROSAN fittings (e.g., press, weld, or compatible mechanical connection) and ensure the joint is clean and correctly positioned. Threaded connections on the 1/2" branch should be sealed with an appropriate thread sealant or tape suitable for potable water if used in drinking-water systems. Tighten threaded components to the manufacturer’s recommended torque values and pressure-test the assembly after installation to verify leak-tightness.

What to consider before purchase

• Confirm compatibility of joining method for d42 stainless pipe (press, weld, or mechanical coupling)
• Ensure 1/2" female thread type matches the mating component and local plumbing standards
• Verify material choice (stainless NIROSAN) meets system corrosion and potable water requirements
• Check system pressure and temperature limits against intended application

Usage recommendations

Use appropriate sealing materials for threaded potable water connections, follow SANHA installation guidelines for NIROSAN stainless fittings, and perform pressure testing after assembly to ensure system integrity.
