SANHA transitional nipple SANHA-Therm ZWxGZ 88.9×3 (copper/steel)

The SANHA transitional nipple SANHA-Therm ZWxGZ 88.9×3 (copper/steel) is a mechanical adapter designed to connect pipes made of different materials or with different connection types in heating and plumbing systems. With an outer diameter of 88.9 mm and a wall thickness of 3 mm, this transitional nipple provides a durable bridge between copper and steel pipework where a reliable, pressure-resistant joint is required. The component is engineered for use in metal pipe networks and intended to maintain flow integrity while compensating for differences in material properties and connection standards.

Advantages

This transitional nipple offers robust mechanical strength due to its matched wall thickness and outer diameter, ensuring stable connections under typical thermal and hydraulic loads. The design facilitates a secure transition between copper and steel pipes, reducing the need for complex fittings. Its construction supports standard installation methods used by professional plumbers and heating technicians, and it helps preserve system tightness and operational reliability when joining dissimilar metals.

Suitable for

• Joining copper and steel pipes in heating systems
• Repairs and retrofits where mixed-metal pipework must be connected
• Plumbing installations requiring a mechanical transition between different connection types
• Industrial and commercial metal piping networks

Key specifications

• Outer diameter: 88.9 mm
• Wall thickness: 3 mm
• Material transition: copper to steel
• Type: transitional nipple (ZWxGZ design)
• Application area: heating and plumbing metal pipe networks

How to use

Prepare both pipe ends by cleaning and deburring to ensure correct alignment and seating. Select compatible joining methods for each material—appropriate soldering, brazing, flaring, or mechanical coupling techniques may be required depending on the system and local codes. Slide the transitional nipple into position and complete the chosen connection procedures, verifying that seals or welds meet the project’s pressure and leak-tightness requirements. After installation, perform a pressure test according to the applicable standards to confirm proper installation.

Usage recommendations

Use the SANHA transitional nipple in accordance with project specifications and local plumbing or heating codes. When connecting dissimilar metals, consider corrosion protection measures such as dielectric fittings or suitable coatings and ensure all materials are compatible with the transported medium and operating temperatures.
