Crimp Reducing Coupler 25 x 16 mm Kisan WL24.04.42.20

Kisan crimp reducing coupler 25 x 16 mm WL24.04.42.20 is a press-type plumbing fitting engineered to join copper or compatible metal pipes of different diameters. The coupler provides a reliable mechanical and fluid-tight connection while reducing pipe size from 25 mm to 16 mm, creating a compact transition suitable for water supply and heating installations. Its low-profile design is intended for permanent, concealed or exposed tubing runs where a secure reduction is required.

Advantages

The press-style reducing coupler delivers a consistent, leak-resistant joint without the need for soldering, which reduces installation time and eliminates open flame risks. Its construction ensures a stable mechanical connection that maintains flow integrity under normal pressure and temperature conditions typical for domestic plumbing and central heating systems. The compact form factor minimizes space usage and helps create a neat piping layout with a smooth internal bore to reduce flow disruption.

Suitable for

• Reducing supply lines from 25 mm to 16 mm in potable water systems
• Linking different-diameter segments in central heating circuits
• Repairs or modifications in existing copper or compatible metal pipework
• Installations where a permanent, low-profile reduction is required

Key specifications

• Connection type: press crimp coupling for mechanical joining
• Pipe diameters: reduces from 25 mm to 16 mm
• Material compatibility: copper and compatible metal piping
• Operating application: potable water and heating systems
• Design: low-profile, in-line reducing coupler

How to use

Prepare pipe ends by cutting square and deburring inner and outer edges to ensure full insertion. Slide the press sleeve or tool over the coupling as required by the press system being used, insert each pipe end fully into the correct side of the coupler, and make the press connection following the press tool manufacturer's instructions. Verify the joint visually for correct mark alignment and perform a pressure test of the system after installation to confirm fluid-tight integrity.

Usage recommendations

Use compatible press tools and approved jaws sized for 25 mm and 16 mm connections. Do not use the coupler with incompatible pipe materials or in systems exceeding the pressure and temperature ratings of the pipework. Ensure cleanliness of pipe surfaces and remove any residues before pressing. After installation, inspect for leaks and follow local regulations for potable water and heating system installations.
