Crimp Sleeve Perfexim 733 25 x 20 mm – plumbing compression connector

The Perfexim crimp sleeve 733 in size 25 x 20 mm is a press-type plumbing connector designed to join two pipes with a diameter reduction from 25 mm to 20 mm. Manufactured for mechanical pressing installations, this connector provides a permanent, leak-resistant joint when installed with compatible press tools and rings. It is suitable for potable water and heating systems where a reliable reduced-diameter connection is required.

Advantages

This press sleeve is engineered for secure mechanical joining, offering consistent compression fit and long-term stability in closed piping systems. The design minimizes the risk of leaks compared with soldered or threaded reductions, and it speeds up installation time by eliminating the need for heating or adhesives. The connector is compatible with standard press-installation workflows, enabling repeatable results when used with appropriate press jaws and sealing rings.

Suitable for

• Reducing pipe diameter from 25 mm to 20 mm in potable water systems
• Connecting pipes in closed heating and radiator circuits requiring a reduction
• Situations where press-fit, permanent connections are preferred over soldering or threading

Key specifications

• Function: press-type compression connector for diameter reduction
• Outer diameter transition: from 25 mm to 20 mm
• Application: potable water and heating systems
• Connection method: mechanical pressing with compatible press rings and jaws
• Intended use: permanent, leak-resistant joints in press installations

How to use

Ensure pipe ends are cut square, deburred and cleaned before assembly. Select the correct sealing ring and place it on the pipe as required by the press system manufacturer. Insert the smaller and larger pipe ends into the corresponding ends of the sleeve until they fully seat. Position the press tool jaws over the sleeve according to the tool and sleeve alignment marks, then perform the press operation following the press tool manufacturer’s instructions. Verify the pressed joint visually and, if required, perform a pressure test in accordance with installation norms.

Usage recommendations

Use only compatible press tools, jaws and sealing rings specified for press-type connectors; follow local plumbing codes and the press tool manufacturer’s guidelines for pressure testing and material compatibility to ensure a durable, leak-free connection.
