Comap press-fit equal tee 40x3.5 mm, copper piping fitting

Comap press-fit equal tee 40x3.5 mm is a copper piping fitting designed to create a three-way branch with equal bore in plumbing and heating systems. The part is made for press (crimp) installation and provides a sealed connection without soldering, suitable for potable water, heating circuits and general plumbing applications where a 40x3.5 mm copper tee is required.

Advantages

The press-fit connection eliminates the need for heat or solder, reducing installation time and risk associated with open flame. Manufactured in copper, the fitting offers corrosion resistance and long-term compatibility with copper piping systems. The equal tee geometry ensures consistent flow characteristics across all three outlets and supports standard press tools and jaws for reliable, repeatable joints.

Suitable for

• Domestic potable water distribution
• Heating circuits and radiator connections
• Plumbing branch connections in residential and commercial buildings
• Installation projects requiring solder-free press-fit joints

Key specifications

• Material: copper
• Connection method: press-fit (crimp)
• Nominal size: 40 mm outer diameter
• Wall thickness: 3.5 mm
• Configuration: equal tee (three outlets with same bore)

How to use

Prepare the copper pipes by cutting squarely and deburring the cut ends. Verify pipe dimensions and wall thickness match the fitting specification (40 x 3.5 mm). Insert the pipe fully into each tee socket until it reaches the stop. Use an appropriate press tool and jaw size for 40 mm copper fittings, aligning the tool squarely on the fitting marking. Perform the press operation according to the press tool manufacturer's instructions to form the permanent joint. After pressing, visually inspect the connection and test the system for leaks following applicable standards and local codes.

Usage recommendations

Store fittings in a dry environment to avoid contamination. Use compatible press tools and follow manufacturer guidelines for inspection and pressure testing. Do not attempt to solder or use thread sealants on the pressed joints; if a different joining method is required, select fittings designed for that method.
