110mm Rubber Wall Seal for Plastic Tanks & Chambers
The 110mm Rubber Wall Seal is designed to form a secure, watertight connection between 4 inch waste pipes and plastic tanks or chambers. The seal profile provides multiple sealing points to support long-term performance in drainage and wastewater applications.
It is suitable for fast, cost-effective installation where pipework passes through chamber or tank walls, helping to accommodate minor movement and angular deflection without compromising the seal.

Installation Guidance
Installation requires a 140mm hole to be formed in the tank or chamber wall using a suitable hole cutter. The rubber seal is then fitted into the opening before inserting the 110mm pipe to achieve a watertight connection.
