FloPlast Ring Seal Soil Rubber Boss Adaptor - 50mm 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.

Ring Seal Soil Systems

Ring Seal Soil and vent is the most commonly used soil system in domestic and non-industrial commercial properties in the UK.

Our FloPlast ring seal soil system is compatible with most other soil systems that are manufactured to British/European standard.

To install any pipe or fitting into another ring seal fitting, first make sure the end of the pipe has been chamfered. Clean off any dirt or debris and lubricate the joint with silicon lubricant. Push the pipe in squarely until resistance is felt, then withdraw it very slightly to allow for any potential system expansion.
