450mm Inspection Chamber Riser Ring Seal

To be used in conjunction with the 450mm Inspection Chamber Risers (B5397), this underground inspection chamber riser sealing ring is 450mm in size and designed to seal risers.

A typical 450mm chamber system can comprise of a chamber base, risers, ring seals, restrictor ring and a suitable cover & frame.

Manufactured in the UK by Brett Martin also provides the installer with a reliable product that will continue to perform. Combining ease of installation with maximum performance, the chamber assemblies meet requirements of Building Regulations Part H1.

We would recommend this product and the rest of the Underground Drainage range to be installed with Lubricant to help with pipe jointing any rubber seal connections in PVC, clay and concrete.
