Compression fitting Comap MultiSkin brass/tinned 26x3/4 for plumbing connections

Compression fitting Comap MultiSkin brass/tinned 26x3/4 is a mechanical coupling designed to join 26 mm copper or multilayer pipes to 3/4" threaded fittings. The fitting features a brass body with a tinned finish to improve corrosion resistance and ensure reliable contact with potable water and central heating media. It creates a leak-resistant seal without the need for soldering, making installation faster and suitable for repair or new-build plumbing work.

Advantages

The MultiSkin compression fitting provides a secure mechanical joint that resists leaks under normal domestic water and heating pressures. Its brass construction with tinned surface offers increased durability and corrosion protection compared with untreated fittings. The design accommodates both copper and multilayer pipes and enables direct connection to standard 3/4" threaded components, eliminating the need for additional adapters or soldering in many installations.

Suitable for

• Connection of 26 mm copper or multilayer pipes to 3/4" threaded valves and appliances
• Domestic potable water supply systems
• Central heating circuits and radiator connections
• Repair and retrofit plumbing work where soldering is impractical

Key specifications

• Material: brass body with tinned finish for enhanced corrosion resistance
• Pipe connection size: 26 mm outer diameter
• Threaded fitting size: 3/4" female/male thread interface
• Connection type: compression (mechanical) joint, no soldering required
• Suitable media: potable water and heating system fluids
• Operating environment: residential plumbing and heating systems

How to use

Ensure the pipe end is cut square, deburred and free of damage. Slide the compression nut and olive (if separate) onto the pipe, insert the pipe fully into the fitting body, and tighten the compression nut by hand, then finish with a wrench to the manufacturer-recommended torque to form a leak-tight seal. Do not overtighten, as excessive torque may deform the pipe or olive. After assembly, pressurize the system and inspect the joint for leaks; retighten slightly if necessary following recommended practice.

Usage recommendations

Use with clean, undamaged copper or approved multilayer piping. For potable water installations, follow local plumbing codes and flush the system before regular use. When connecting to heating systems, allow for thermal expansion and ensure fittings are accessible for future maintenance.
