Double-sided press-fit elbow Comap 40 x 3.5 mm

Comap double-sided press-fit elbow 40 x 3.5 mm is a press fitting engineered to create a 90° joint in press-fit plumbing and heating systems. It is intended for use with compatible copper or steel press fittings and press tools to form a permanent, leak-resistant connection suitable for water supply, heating circuits and industrial installations that require a robust elbow component.

Advantages

The press-fit design ensures quick and repeatable installation without soldering or welding, reducing on-site work time. Manufactured to meet material and dimensional standards for press systems, the elbow provides mechanical strength and corrosion resistance appropriate for potable water and heating applications. Its double-sided press interface allows secure connections on both ends using standard press jaws or rings, delivering a uniform seal and minimizing the risk of joint failure under operating pressure.

Suitable for

• Creating 90° turns in domestic and commercial water supply systems
• Connecting sections in central heating and radiator circuits
• Industrial piping where press-fit copper or steel fittings are specified
• Retrofit and new-build plumbing installations requiring durable press joints

Key specifications

• Nominal size: 40 mm
• Wall thickness compatibility: 3.5 mm
• Elbow angle: 90°
• Connection type: double-sided press-fit
• Material compatibility: copper and steel press-fit systems
• Application: potable water, heating and industrial installations

How to use

Prepare pipe ends by cutting square and removing burrs and debris; ensure the pipe dimensions match the 40 x 3.5 mm specification. Slide the press fitting onto the pipe end until it seats fully. Position the press tool and compatible jaw or ring over the fitting and perform the press following the tool manufacturer's instructions. Verify the pressed joint visually and, if required, perform a pressure test to confirm system integrity before commissioning.

Usage recommendations

Use only press tools and jaws certified for the press system to ensure correct compression and sealing. Confirm material compatibility (copper or steel) and wall thickness prior to installation. Follow local regulations and industry standards for potable water and heating systems, and perform pressure tests after installation to detect leaks.
