Perfexim compression screw tee 16 x G1/2 x 16 model 739 (MPN 62-739-1615-000)

The Perfexim compression screw tee 16 x G1/2 x 16 model 739 is a plumbing fitting designed to join three pipe runs: two 16 mm compression ends and a G1/2 threaded branch. Intended for installations where a transition is needed between metric compression pipes and a G1/2 threaded connection, this tee offers a compact solution for domestic and light commercial water and heating systems. The design provides a sealed junction between rigid or semi-rigid copper/plastic pipes and a threaded outlet for valves, meters, or appliances.

Advantages

The tee uses compression screw connections on the 16 mm ends to create a secure mechanical seal without soldering, reducing installation time and the need for special tools. The G1/2 threaded branch enables straightforward attachment of standard valves, fittings or sensors. Manufactured to meet typical plumbing tolerances, the component provides reliable fluid-tight performance in potable water and central heating circuits when installed correctly.

Suitable for

• Joining two 16 mm supply or return lines with a G1/2 threaded branch
• Connecting valves, flow meters, taps or sensors with G1/2 thread to compression pipework
• Domestic water distribution and radiator/heating system connections

Key specifications

• Compression connection size: 16 mm (two ends)
• Threaded branch size: G1/2
• Configuration: tee (two inline compression ends with one threaded branch)
• Material: corrosion-resistant fitting material suitable for potable water and heating systems
• Connection type: compression screw on two ends, parallel pipe thread on branch

How to use

Prepare the pipe ends by cutting square and deburring the tubes to ensure proper seating of the compression olives and nuts. Slide the compression nut and olive onto each 16 mm pipe, insert the pipe fully into the compression ends of the tee, then tighten the compression nuts to the manufacturer's recommended torque to form a leak-tight joint. Wrap the G1/2 threaded branch with appropriate thread sealant or PTFE tape if required, then attach the mating threaded fitting and tighten to secure the connection. Verify alignment and check for leaks under pressure after installation.

Usage recommendations

Use the fitting with compatible pipe materials and sizes, and follow standard plumbing practice: ensure clean cuts, correct seating of compression olives, and controlled tightening. When connecting to sensitive devices (meters, valves, sensors), avoid over-tightening the threaded joint and follow the device manufacturer's installation guidance. Pressure-test the system and inspect joints periodically.
