Press-fit tee Comap GZ 20 x 1/2 x 20 — plumbing fitting, model 734ECE-02

Comap press-fit tee GZ 20 x 1/2 x 20 (model 734ECE-02) is a press-connection plumbing fitting designed to form a T-branch in pipe systems. The fitting combines two 20 mm press sockets with a 1/2" threaded branch, enabling connection between press-fit copper or compatible alloy pipes and a standard 1/2" threaded outlet. It is intended for potable water and heating distribution systems where press joints are preferred for speed and reliability.

Advantages

The press-fit tee provides a consistent mechanical press connection that reduces assembly time compared with traditional soldering or compression joints. Its configuration allows a direct join between 20 mm press lines and a 1/2" threaded component, offering flexibility when integrating valves, gauges or secondary branches. The design supports leak-resistant distribution runs and is suitable for repeated installation practices in residential and light-commercial plumbing.

Suitable for

• Potable water distribution lines
• Central heating pipe circuits
• Connecting 20 mm press pipes to 1/2" threaded valves or fittings
• Retrofit or new-build plumbing installations using press technology

Key specifications

• Connection configuration: 20 mm press × 1/2" threaded × 20 mm press
• Type: T-piece for press-connection systems
• Intended media: potable water and heating fluids
• Materials: corrosion-resistant metal alloy suitable for press joining
• Application: indoor plumbing and heating distribution

How to use

Prepare the pipe ends by cutting square and deburring to ensure full insertion into the press sockets. Insert the 20 mm pipes fully into each press end until they reach the internal stop, and tighten the 1/2" threaded component to the central branch as required. Use the appropriate press tool and jaws specified for the pipe material and fitting series, performing the press operation until the tool indicates a completed joint. Verify the pressed connections visually and, where applicable, perform a pressure test in accordance with local installation standards.

Usage recommendations

Use compatible press tooling and jaws rated for 20 mm press fittings and follow manufacturer guidelines for installation. Avoid using damaged or deformed pipes and inspect sealing surfaces before pressing. After installation, carry out pressure testing and routine checks to confirm system integrity.
