Perfexim plumbing tee 70A 20×16×20 mm – 61-010-1620-000

The Perfexim plumbing tee 70A 20×16×20 mm is a three-way connector engineered to join a 20 mm supply line with a 16 mm branch and a continuing 20 mm run. Intended for domestic and light commercial water distribution, this tee enables a compact transition between mixed pipe diameters while maintaining flow continuity. The tee is designed for standard plumbing installations where a reduction to a smaller diameter is required and where a return to the original diameter is needed downstream.

Advantages

This tee provides a reliable, space-efficient connection for mixed-diameter piping, reducing the need for multiple fittings. Its 70A designation indicates suitability for typical water distribution pressures in residential and light commercial systems. The simple geometry supports straightforward installation and minimizes flow disturbance at the junction between 20 mm and 16 mm runs.

Suitable for

• Domestic cold and hot water distribution systems
• Light commercial plumbing installations
• Branching a 20 mm main to a 16 mm feed for radiators, fixtures or appliances
• Repair and retrofit work where mixed pipe sizes are present

Key specifications

• Connection layout: three-way (tee) with one branch reduced
• Pipe diameters: main lines 20 mm, branch 16 mm
• Material: engineered for standard plumbing use (compatible with common piping materials)
• Designation: 70A pressure class for typical residential/light commercial water systems
• Application: water distribution and internal plumbing connections

How to use

Prepare the piping by cutting clean, square ends and deburring each pipe. Select appropriate joining method compatible with the product material and the pipes in use (for example push-fit, compression, or solvent-weld depending on the tee construction and pipe type). Insert or secure the 20 mm mains and 16 mm branch according to the chosen joining system, ensuring full insertion and proper sealing. After assembly, pressure-test the circuit in line with local plumbing codes to verify leak tightness before final insulation or concealment.

Usage recommendations

Use this tee in systems where a controlled reduction from 20 mm to 16 mm is required and where the pressure and temperature range match standard domestic plumbing conditions. Ensure compatibility between the tee material and the pipe material (e.g., PEX, CPVC, copper) and follow manufacturer guidance for joining methods and pressure testing.
