Brass/zinc recessed press-fit connection kit Comap MultiSkin 16 x 1/2, 150 mm centres, offset (model 7507W1612)

Recessed press-fit connection kit Comap MultiSkin 16 x 1/2, 150 mm centres, offset is designed for concealed plumbing installations where a reliable mechanical joint is required between pipework and fixtures. The kit combines brass and zinc components to provide a compact, press-fit solution suited to under-plaster or wall-mounted installations. Its 150 mm centre spacing with an integrated offset allows alignment with common valve and fixture layouts in domestic and light-commercial heating and water systems.

Advantages

The Comap MultiSkin kit delivers a consistent press-fit connection that reduces installation time compared with threaded or soldered joints. Brass elements provide corrosion resistance at the water-contact surfaces while zinc parts contribute to cost-effective structural support. The built-in offset simplifies alignment behind finished walls, and the recessed design keeps connections concealed to maintain a neat appearance once plastered or covered. The assembly is suitable for potable water and heating applications when installed according to applicable codes.

Suitable for

• Connecting 16 mm pipework to 1/2" fixtures and valves
• Concealed under-plaster or in-wall plumbing installations
• Domestic and light-commercial heating and hot/cold water systems
• Renovation projects where an offset connection is required

Key specifications

• Connection dimensions: 16 mm to 1/2 inch
• Centre spacing: 150 mm with integrated offset
• Materials: brass and zinc components
• Installation type: recessed / in-wall press-fit assembly
• Application: plumbing for heating and potable water systems

How to use

Install the recessed unit at the specified 150 mm centres and secure within the wall box or mounting frame following local installation rules. Prepare 16 mm pipes by cutting square and deburring the ends, then insert pipes into the press-fit fittings until they reach the internal stop. Use an appropriate press tool and jaws calibrated for MultiSkin press fittings to complete the mechanical joint. Once pressed, conceal the assembly with suitable backing and finish materials; ensure accessibility where required for service valves.

Usage recommendations

Verify compatibility with pipe material and local plumbing standards before installation. Use only press tools and dies recommended for press-fit systems and follow manufacturer torque and testing instructions. Pressure-test the system after installation and before closing walls. For installations supplying potable water or critical heating circuits, observe relevant codes and use corrosion-compatible materials at dissimilar metal interfaces.
