System MKR

Wedge seal for concrete pipes

The M.O.L. concrete pipe seal system MKR is a wedge shaped sealing system for concrete and reinforced concrete pipes. It is mounted on the front end of a pipe and guarantees a reliable connection in compliance with DIN EN 1916 and DIN V 1201. The MKR seal also fulfils the requirements of DIN EN 681-1.

Material

The material used, SBR (styrene-butadiene rubber), is ideal for use in sewage systems and conforms to DIN EN 681-1 WC 40 (hardness 40 ± 5 IRHD). The MKR seal is tested and inspected for quality by MPA NRW (Dortmund).

Pipe manufacture

The MKR seal is fixed to the cleaned end of the pipe and is positioned in front of the overhang as shown. Careful lifting and releasing will ensure that the tension of the seal is balanced.

Note for pipe installation

When laying pipes, apply a lubricant (e.g. M.O.L.) to the surface of the pipe collar. Centre the spigot into the plunger and tighten the pipes.
