FloPlast Ring Seal Soil Rubber Boss Adaptor - 40mm Black

This flanged rubber boss adaptor is used in conjunction with either an SP583 Short Boss Pipe, an SP581 boss pipe or an SP319 strap boss to connect a waste pipe into a 110mm soil pipe. It can also be used inside the boss shoulders of other fittings such as junctions.

This adaptor is a push fit joint that is sealed by the moulded rubber flanges on the outer edge.
