Description
Flexible drainage connector from VIPSeal for joining 4 inch clay drainage pipe to compatible 4 inch PVC underground drainage pipe. This VAC4000 adaptor coupling is designed for pipe connections where the outside diameters differ, making it useful for drainage repairs, alterations and clay-to-plastic pipe connections.
The VAC4000 size range suits 121–136mm pipe on one side and 110–121mm pipe on the other. This makes it suitable for many 4 inch clay to 4 inch PVC drainage connections where the pipe sizes fall within the correct outside diameter range.
VIPSeal adaptor couplings are step moulded from EPDM rubber and fitted with two stainless steel tension bands. This gives a secure, practical connection for low pressure and non-pressurised underground drainage systems.
Before fitting, always measure both pipe outside diameters. Clay pipe can vary in size, so checking the pipework first helps ensure the connector is suitable for the job.

How to Use a Flexible Drainage Connector
First, measure the outside diameter of both pipes. Check that one pipe sits within the 121–136mm range and the other sits within the 110–121mm range.
Next, clean both pipe ends. Remove grit, dirt, grease and damaged edges before fitting the connector.
Slide the connector onto one pipe end. Then line up the second pipe and centre the connector over the joint. Finally, tighten both stainless steel bands evenly until the fitting is secure.
