Compression Tee Perfexim 708 20 mm x G 1/2" (male) x 20 mm – plumbing connector

Perfexim 708 compression tee (20 mm x G 1/2" male x 20 mm) is a compact plumbing connector designed for water supply and heating installations. The fitting has two 20 mm compression ends and a central G 1/2" male threaded branch, allowing connection of 20 mm pipes with a device or branch using a 1/2" thread. The design enables a secure mechanical seal without soldering, making it suitable for residential and light-commercial piping systems where a threaded outlet is required.

Advantages

The compression tee provides a reliable, leak-resistant joint through mechanical compression fittings suitable for copper or compatible plastic pipes. Its compact form factor reduces space requirements at junctions and simplifies installation by eliminating the need for hot works or specialized joining tools. The G 1/2" male branch allows direct attachment of fixtures, valves or adapters with corresponding threads, enabling versatile system layouts and straightforward maintenance access.

Suitable for

• Connecting 20 mm supply pipes in domestic water installations
• Creating a 1/2" threaded outlet for valves, gauges or shower fittings
• Branching heating system circuits with compact junctions
• Retrofit and repair work where soldering is impractical

Key specifications

• Compression ends: 20 mm two-way connection
• Threaded branch: G 1/2" male
• Application: potable water and heating installations
• Connection type: mechanical compression with ferrule
• Material: manufacturing material suitable for plumbing use (metal alloy common for compression fittings)
• Installation: push-fit followed by nut tightening to form compression seal

How to use

Prepare pipe ends by cutting square and deburring. Slide the compression nut and ferrule onto each 20 mm pipe, insert the pipe fully into the compression end of the tee, then hand-tighten the nut and finish with an appropriate wrench to compress the ferrule and form a seal. For the central branch, screw the 1/2" male thread into the mating female fitting or connect a threaded accessory. Verify alignment and tighten to the manufacturer's recommended torque where available. After assembly, pressurize the system and check for leaks at all joints.

Usage recommendations

Use with pipes and accessories compatible with 20 mm compression fittings and G 1/2" threads. Avoid over-tightening the compression nuts to prevent deformation of the ferrule or pipe. When used in potable water systems, ensure materials comply with local regulations for drinking water. For installations under pressure or in heating circuits, perform pressure testing following local codes and manufacturer guidance.
