225mm Twinwall Ring Seal

This 225mm twinwall rubber seal is black in colour and designed to connect onto 225mm twinwall fittings, creating a watertight sealed system. A sealing ring should be used at each joint.

As a guideline, you will require:

• Two ring seals per one coupler


• Two ring seals per one bend


• Three ring seals per one junction

For a sealed carrier system, before a fitting is placed onto the pipe you would usually sit the seal between the 1st and 2nd rib corrugation from the end.

We highly recommend this product and the rest of the twinwall range to be installed with lubricant to help with pipe jointing fittings and rubber seal connections.

BBA approved and manufactured in the UK by Naylor provides the installer with a reliable product that will perform. This product is designed to suit Naylor Metrodrain Twinwall, therefore it may not fit other manufactures twinwall products.
