Tee fitting Perfexim 739 press-to-screw 20 mm x G1/2 x 20 mm (model 62-739-2015-000)

Perfexim 739 press-to-screw tee fitting with two 20 mm press ends and a central G1/2 threaded branch is designed for connecting three pipe runs where a combination of press connections and a threaded outlet is required. The fitting joins two 20 mm press-type pipes while providing a G1/2 screw connection in the middle for attaching valves, instruments or service lines. It is intended for potable water and heating installations and is compatible with standard press tools and G1/2 threaded accessories.

Advantages

This press-to-screw tee offers a reliable mechanical press connection on the lateral outlets together with a standard threaded middle branch, allowing quick installation without soldering. The dual-connection design reduces the need for additional adapters and minimizes leak points by combining press fittings with a controlled threaded interface. Durable construction suitable for potable water and heating systems ensures stable performance when installed according to applicable standards and tool specifications.

Suitable for

• Branching potable water distribution lines
• Connecting heating loops and radiator feeds with a valve on the threaded outlet
• Integrating meters, drains or service valves requiring a G1/2 connection
• Mixed systems where press connections are preferred for pipe runs and threaded connections for accessories

Key specifications

• Press ends: 20 mm on both lateral outlets
• Threaded branch: G1/2 (female)
• Connection types: press (crimp) on side outlets, screw-thread in the middle
• Typical applications: potable water and heating systems
• Compatibility: designed for use with standard press tools and G1/2 threaded fittings

How to use

Prepare the pipe ends by cutting square and deburring, then insert the pipes fully into the 20 mm press sockets. Use the appropriate press tool and jaw for 20 mm press fittings and perform the press operation following the tool manufacturer's instructions. On the central G1/2 branch, apply an appropriate thread sealant or tape to the male thread of the valve or accessory, then hand-start and tighten with a wrench to the recommended torque for the accessory. Verify all connections and pressure-test the system according to local regulations.

Usage recommendations

Use manufacturer-approved press tools and jaws sized for 20 mm fittings; follow local plumbing codes and recommended pressure-test procedures. Do not exceed the temperature and pressure ratings of the installed system components, and ensure compatible materials are used for threaded accessories.
