Elbow fitting Comap Kolano 45 press-fit double-sided 40x3.5 mm

Comap Kolano 45 press-fit double-sided 40x3.5 mm is a 45-degree elbow fitting designed for reliable, solder-free connections in plumbing and heating systems. The fitting features two press-fit ends sized for 40x3.5 mm pipes and is intended for use with compatible copper or metal pipe systems. Its compact 45° angle enables smooth direction changes and space-efficient routing where bends are required.

Advantages

The press-fit design provides a secure, leak-resistant joint without the need for flame or solder, reducing installation time and safety risks. Double-sided press connections allow quick assembly on both sides of the elbow and ensure consistent mechanical strength. The 45-degree geometry supports smoother flow compared with sharp angles and helps minimise stress on adjacent pipe runs. The fitting is compatible with standard metal piping materials used in domestic and commercial installations.

Suitable for

• Plumbing systems in residential buildings
• Heating and radiator connections
• Commercial and light-industrial piping installations
• Tight or compact routing where a 45° change of direction is required

Key specifications

• Angle: 45 degrees for directional change
• Connection type: double-sided press-fit
• Pipe compatibility: designed for metal pipes with 40 mm external diameter and 3.5 mm wall thickness
• Material: metal construction suitable for plumbing and heating applications
• Application: suitable for potable water, heating circuits and general plumbing where press connections are accepted

How to use

Prepare pipe ends by cutting square and deburring the inner and outer edges. Mark insertion depth on the pipe if required by the press system, then insert the pipe fully into each press end of the elbow. Use the appropriate press tool and jaw for 40x3.5 mm press fittings, applying a single, complete press cycle to each connection according to the press-tool manufacturer’s instructions. After pressing, verify the mechanical and visual indicators on the fitting if present, and conduct a pressure test of the system before commissioning.

Usage recommendations

Use only press tools and jaws specified for 40x3.5 mm press fittings and follow the tool and fitting manufacturer’s guidance. Ensure system cleanliness before assembly and test the completed installation at the required test pressure. Do not flame-solder press connections; these fittings are designed exclusively for press assembly.
