Compression fitting Perfexim GZ 25 mm x 3/4" (61-001-2520-000)

Compression fitting Perfexim GZ 25 mm x 3/4" is a mechanical plumbing connector designed to join a 25 mm pipe to a 3/4" male threaded outlet. The fitting creates a leak-resistant transition between plastic or metal pipework and threaded components without the need for soldering or welding, making it suitable for installation and repair of water supply and central heating systems.

Advantages

The compression design provides a secure, reusable joint that can be assembled with simple tools. Its construction ensures reliable sealing under typical domestic water pressures and heating system conditions. As a mechanical fitting, it reduces installation time compared with soldered or flanged connections and enables straightforward disassembly for maintenance or replacement.

Suitable for

• Connecting 25 mm pipes to 3/4" male threaded valves, radiators or taps
• Water supply lines in residential and commercial buildings
• Central heating pipework where a pipe-to-thread transition is required
• Repair or retrofit work where soldering is impractical

Key specifications

• Pipe connection size: 25 mm compression
• Threaded connection: 3/4" male thread
• Connection type: mechanical compression (screw) fitting
• Material: metal components suitable for potable water and heating systems
• Sealing method: compression ring/gland for leak-resistant joint

How to use

Prepare the pipe end by cutting it square and removing burrs. Slide the nut and compression ring (olive) onto the pipe, then insert the pipe into the fitting body until it seats fully. Tighten the nut by hand and finish with a wrench to the manufacturer’s recommended torque to compress the ring and form the seal. Connect the 3/4" male thread to the mating component and, if required, use appropriate thread sealant or tape on the threaded portion. After assembly, pressurize the system and inspect the joint for leaks.

Usage recommendations

Use this compression fitting with pipes and threaded components that match the specified sizes. Avoid over-tightening the nut to prevent damage to the compression ring or pipe. For plastic pipes, ensure the pipe type is compatible with compression fittings or use a liner/insert where recommended. If used in heating systems, follow applicable system flushing and water treatment guidelines to prevent corrosion and prolong service life.
