Compression fitting Perfexim 733 U-type 32×25 mm

Perfexim 733 U-type 32×25 mm is a compression (press) fitting engineered to connect copper or multilayer pipes while reducing diameter from 32 mm to 25 mm. The fitting creates a sealed, permanent mechanical joint without the need for soldering, making it suitable for installation in water distribution and central heating systems where a reliable reduction coupling is required. The U-type design facilitates alignment and compact routing in tight installation spaces.

Advantages

The compression design delivers consistent, leak-resistant joints and removes the need for heat-based joining methods. Compatible with copper and multilayer piping, the fitting supports a durable mechanical connection that resists vibration and pressure cycles typical of heating and plumbing systems. Its compact form factor simplifies installation in confined spaces and allows straightforward integration into existing pipe runs.

Suitable for

• Domestic and commercial water supply pipelines
• Central heating systems and radiator connections
• Branching or reducing pipework where a 32 mm to 25 mm transition is required
• Repairs and upgrades where soldering is impractical or restricted

Key specifications

• Connection type: compression (press) fitting
• Material compatibility: copper and multilayer pipes
• Pipe size transition: 32 mm to 25 mm
• Joint type: sealed, permanent mechanical connection
• Typical applications: potable water and central heating systems

How to use

Prepare both pipe ends by cutting square and deburring, then ensure they are clean and free of oxidation or debris. Slide the compression components onto the pipes according to the fitting manufacturer’s assembly order, insert the smaller-diameter pipe into the fitting until it seats correctly, and apply the required pressing tool or torque specified for compression installation to form the sealed joint. Verify alignment before completing the press operation, then test the system for leaks under working pressure after installation.

Usage recommendations

Use appropriate pressing tools and jaws sized for the fitting and pipe diameters. Follow local plumbing codes and manufacturer guidance regarding installation pressure limits, supported media (water and heating fluids), and any required system flushing or chemical compatibility checks prior to commissioning.
