Buy a Manhole Riser Seal Spare Sealing Ring 320/470mm
For use with our budget manhole risers. Please note that our budget manhole risers do not come with a pre-lubricated sealing ring installed.
These 470mm sealing rings are for use with EasyMerchant’s Budget 470mm Risers. Every riser must be installed using a lubricated sealing ring (lubricants sold individually at EasyMerchant) in order to guarantee a sealed manhole base impervious to water or gasses.
The entire manhole base system will lose any guarantees and doesn’t meet building regulations if they are not installed using a sealing ring included so please make sure that one is used with each riser. The small cost of adding a sealing ring is always worth the cost considering the cost of retrofitting should the system begin to leak.
