Reducing press-fit elbow tee Comap MultiSkin PPSU 20 × 20 × 16 mm

The Comap MultiSkin reducing press-fit elbow tee in PPSU is a press fitting designed to branch a 16 mm line from a 20 mm main pipe in plumbing, heating and sanitary systems. Manufactured from PPSU (polyphenylsulfone), this reducing tee integrates press ends sized 20 × 20 × 16 mm and is intended for applications that require a reliable, leak-resistant connection with a change of diameter. The fitting is suitable for use with potable water and heating circuits where a compact, low-profile press connection is needed.

Advantages

The PPSU construction provides chemical resistance and long-term mechanical stability at elevated temperatures. Press-fit ends deliver fast, consistent joints without the need for soldering or adhesives, reducing installation time and on-site preparation. The reducing elbow tee offers a compact geometry that minimizes space requirements at branch points while maintaining a smooth internal flow path to reduce turbulence and pressure loss.

Suitable for

• Branching a smaller supply line from a larger main pipe in potable water systems
• Heating and radiator feed lines where a diameter reduction is required
• Sanitary installations in residential and light commercial buildings
• Situations that require reliable press connections without hot works

How to use

Select compatible pipe material and press tooling recommended for Comap MultiSkin fittings. Prepare pipe ends by cutting square, deburring and cleaning to ensure proper fit. Insert pipes fully into the press-fit ends and apply the correct press profile using a calibrated pressing tool until a complete press cycle is achieved. After pressing, inspect the joint visually and, where required, perform pressure testing of the system in accordance with applicable standards and local regulations.

Usage recommendations

Use certified pressing tools and jaws compatible with Comap MultiSkin PPSU fittings, follow manufacturer instructions for maximum operating temperature and pressure, and perform system flushing and pressure tests before commissioning to confirm leak-free installation.
