ChamberTite Duct Boot- 4" or 110mm CTB-7450

4" ChamberTite Duct Seal suitable for sealing a 100-110mm rigid or flexible duct into a watertight chamber. Manufactured from nitrile rubber (BS 2751) entry seal complete with stainless steel fixings and galvanised steel clamp ring. The entry boots are suitable for direct burial and provide a flexible seal between duct and entry wall. As all fixings are made accessible internally within the chamber entry boot can be maintained whilst in service.

We offer a comprehensive range of seals to suit most common pipe and duct sizes.

For additional security the duct seal can also be fiited with a bulkhead to prevent cross contamination in the event of a breach within the duct or other chamber. See CTB-7450B.
