Compression fitting Comap DWZ/PWE 32x16 reducing coupling for pipe transition

Compression reducing coupling Comap DWZ/PWE 32x16 is a press-fit fitting designed to join pipes of different diameters with a reliable mechanical connection. Intended for professional and residential plumbing and heating installations, this coupling provides a compact transition between 32 mm and 16 mm pipes and is suitable for potable water, central heating and distribution lines where a pressed, leak-resistant joint is required.

Advantages

The coupling offers a secure pressed connection that reduces the need for soldering or threaded joints, speeding up installation while maintaining mechanical strength. Its compact design saves space in confined installation areas and ensures stable alignment between differing pipe diameters. The product is compatible with standard press tools and provides a durable, leak-resistant seal when installed according to manufacturer guidelines.

Suitable for

• Transitions from 32 mm to 16 mm pipes in potable water systems
• Central heating distribution lines where diameter reduction is required
• Compact plumbing installations and renovation projects with limited access

Key specifications

• Type: compression reducing coupling for press installation
• Connection sizes: 32 mm to 16 mm
• Application: potable water and heating systems
• Installation method: press-fit (mechanical pressing)
• Design: compact transition coupling for space-constrained areas

How to use

Prepare pipe ends by cutting square and deburring internal and external edges. Insert the smaller and larger pipes into the respective ends of the coupling until they reach the internal stop. Position the press tool jaws around the coupling at the designated pressing zone and perform the press according to the tool and sleeve manufacturer's instructions. Verify the pressed joint visually and by a light mechanical check to ensure correct compression and alignment before putting the system into service.

Usage recommendations

Use appropriate press tools and recommended press jaws for the Comap DWZ/PWE coupling, follow local plumbing codes and manufacturer installation instructions, and pressure-test the system after installation to confirm leak-free operation.
