Product information

Description

VIEGA stainless steel reducing coupling 18×15 mm SC model 436223 is a compact coupling designed to connect pipes of different diameters in plumbing and heating systems. Made from stainless steel, it offers corrosion resistance and mechanical strength for reliable joints in residential and commercial installations. The SC reducing coupling provides hydraulic sealing suitable for stainless steel pipes and other compatible materials, ensuring a compact connection with consistent flow characteristics.

Advantages

The stainless steel construction delivers long-term corrosion resistance and durability in potable water, heating and general plumbing applications. The reducing shape enables a smooth transition between 18 mm and 15 mm pipes while maintaining hydraulic integrity. Its compact SC design reduces space requirements at connection points and simplifies installation by aligning mechanical strength with a reliable sealing interface.

Suitable for

  • Connecting stainless steel pipes of 18 mm to 15 mm diameter in plumbing systems
  • Reducing connections in heating and radiator installations
  • Use in potable water and closed-loop systems where corrosion resistance is required
  • Retrofit and new-build residential and light commercial piping projects

Key specifications

  • Material: stainless steel for corrosion resistance and mechanical strength
  • Connection type: reducing coupling for 18 mm to 15 mm pipe diameters
  • Design: compact SC geometry suitable for limited-space installations
  • Sealing: hydraulic sealing interface engineered for reliable, leak-resistant joints
  • Applications: plumbing, potable water, heating and closed-loop systems

How to use

Prepare pipe ends by ensuring they are clean, deburred and cut squarely. Slide the coupling onto the larger diameter pipe, then insert the smaller diameter pipe into the opposite end until the correct insertion depth is reached. Follow the system manufacturer’s installation instructions and common plumbing practice for alignment and support. Verify correct seating and seal engagement before pressurizing the system. After installation, perform a pressure test to confirm the joint is leak-free.

Usage recommendations

Use this VIEGA stainless steel reducing coupling in systems where material compatibility with stainless steel is required. Avoid mixing incompatible metals without appropriate dielectric isolation. For optimal performance, install in accessible locations for inspection and pressure testing, and adhere to local plumbing codes and standards.
