Description
The flexible drainage connector for 4 inch clay pipe is used to join or repair compatible underground drainage pipework. It is useful when connecting plain-ended clay pipe, repairing damaged pipe sections or joining short cut lengths of drainage pipe.
This VIPSeal VDC135 drain coupling suits pipe outside diameters from 120mm to 135mm. It is commonly used with compatible 4 inch clay drainage pipe where the outside diameter falls within the stated size range.
The EPDM rubber body and stainless steel tension bands help create a secure connection when tightened correctly. As a result, this connector is a practical choice for drainage repairs, alterations and underground pipe maintenance.
Flexible Drainage Connector for 4 Inch Clay Pipe
The flexible drainage connector helps join compatible 4 inch clay drainage pipework. It can be used where a rigid fitting is not suitable or where existing pipework needs a flexible repair connection.
Before installation, measure the outside diameter of the pipe. The VIPSeal VDC135 size range is 120mm to 135mm, so both pipe ends must sit within this range.

VIPSeal VDC135 Clay Flexible Connector
This flexible drainage connector is part of the VIPSeal VDC drain coupling range. VIPSeal VDC couplings are used for joining and repairing low and non-pressure drainage systems.
The VDC135 size is suitable for pipe outside diameters from 120mm to 135mm. This makes it useful for many 4 inch clay drainage repair jobs, depending on the exact pipe outside diameter.
The coupling can help join plain-ended pipe, repair damaged sections, connect short pipe lengths or adapt between compatible drainage materials where the pipe sizes match the product range.
Flexible Drainage Connector Installation Use
Install the flexible drainage connector on clean, supported and correctly prepared pipe ends. Cut the pipe square, remove loose material and make sure the coupling sits evenly across the joint.
Next, position the stainless steel tension bands correctly. Then tighten the bands to the recommended 6Nm torque.
Do not over-tighten the bands. Also, check that the pipework has suitable support before backfilling or covering the repair.
Flexible Connector for Drainage Repairs
This connector is useful for builders, groundworkers, plumbers and drainage installers working on underground drainage repairs and alterations.
It can help where existing 4 inch clay pipe needs to be joined, extended or repaired without replacing a larger section of the drainage run.
Compatible Flexible Connector Products
This flexible drainage connector is part of the wider TWS flexible connectors range. You can match it with suitable clay to PVC adaptors, PVC couplers, flexible end caps, internal couplings and underground drainage fittings.
