The Brett Martin 450mm Sealing Ring (B5398) is an essential component for achieving a reliable, watertight joint when constructing underground inspection chambers. Designed specifically to work in conjunction with the Brett Martin B5397 450mm chamber riser and base units, this elastomeric rubber ring prevents groundwater ingress and foul water leakage.

Building regulations require underground drainage networks to remain completely sealed against leaks. The B5398 seal sits securely within the joint profile of the 450mm chamber section, expanding slightly upon compression to form a permanent barrier against water, silt, and root penetration.

Whether you are extending an existing inspection chamber or installing a completely new adoptable or non-adoptable drainage system, this genuine Brett Martin accessory ensures your installation meets strict UK building control standards.
