110mm Underground Drainage Double Socket Slip Coupler

This Kayflow slip coupler connects two plain-ended sections of 110mm underground drainage pipe. Its double socket design contains a push-fit seal at each end. Product code BUG12. Unlike a standard coupler, the slip design does not use a fixed central stop. Therefore, the fitting can slide farther along the pipe during installation. This makes it especially useful when repairing an existing drainage run where the surrounding pipes cannot move apart.

When Should You Use a Slip Coupler?

A standard coupler works well when installers can move the pipe ends during assembly. However, this is often difficult on an existing buried drainage run. A slip coupler provides a practical solution because it can move fully along one pipe end. For example, use this fitting when replacing a damaged section of 110mm pipe. First, slide the coupler onto the existing pipe. Next, position the replacement section. Then slide the coupler back across the joint. As a result, both seals sit across the connected pipe ends. The fitting also suits drainage alterations where access is limited. In addition, it can help join plain-ended pipes when a normal stopped coupler would prevent correct positioning.

Installing the 110mm Coupler

Make sure each pipe end is clean, square and free from damage. If you cut the pipe, chamfer and deburr the new end before fitting. Also, mark the intended socket depth on each pipe so you can centre the coupler over the finished joint. Apply a suitable drainage lubricant to the seals and pipe ends. Then slide the fitting into position without disturbing the sealing rings. Finally, check that the coupler sits evenly across both pipe ends.

Nominal size	110mm
Connection type	Double socket push-fit
Central stop	Yes
Seal type	Fixed rubber sealing rings

Where Can You Use a Double Coupler?

Use this fitting to connect two plain-ended pipes in a new or extended underground drainage system. For example, it can join two cut pipe sections or connect a plain-ended pipe to a compatible plain-ended fitting. The internal central stop provides a clear insertion point for each pipe. As a result, it helps keep the coupler centred across the completed joint. However, the stop prevents the fitting from sliding fully along the pipe. If you need to replace a damaged section within a fixed drainage run, use a slip coupler instead. The Kayflow BUG12 slip coupler has no central stop, so it can slide along the pipe during a repair.

Installing the Double Coupler

First, cut the pipe square and remove any sharp edges. Next, chamfer the pipe end to help it pass through the rubber seal. Also, clean the socket and check that each sealing ring remains correctly seated. Apply a suitable drainage lubricant to the pipe ends. Then push each pipe into the coupler towards the central stop. Follow the system manufacturer’s installation guidance and allow for pipe movement where required. Finally, install the completed drainage run with the correct bedding, gradient and backfill. Follow current Building Regulations and all site-specific drainage requirements. Browse the complete 110mm underground drainage range for compatible pipes, bends, junctions and access fittings.

Where Can You Use This 110mm Underground Drainage Pipe?

Use this pipe for new drainage systems, extensions and repair work. For example, it suits domestic drainage, commercial groundworks and general below-ground pipework. You can use it for both foul water and surface water systems. The 6m length works especially well on long, straight drainage runs. Because the pipe covers more distance, it needs fewer joints than shorter lengths. As a result, it can simplify the layout and reduce the number of separate couplers required.

Installing 110mm Drainage

First, prepare the trench with the correct bedding and fall. Next, check that each pipe end remains clean and free from damage. If you cut the pipe, chamfer the new end before fitting it into a socket. Also, use a suitable drainage lubricant to protect the rubber seal. Finally, follow current Building Regulations and the requirements of the installation site. Correct bedding, jointing and backfilling will help protect the finished drainage system.

Where Should You Use a Square Rodding Point?

Install this fitting where the drainage layout needs a practical cleaning and inspection point. For example, it may provide access at the head of a drain or at another suitable point within a 110mm drainage run. The square alloy top offers a durable finish for external drainage areas. In addition, its compact design takes up less space than a full inspection chamber. However, the rodding point must remain visible and accessible after installation. This product provides maintenance access only. It does not replace an inspection chamber where Building Regulations or the drainage design requires one.

Installing the Square Rodding

First, position the fitting so drain rods can enter the pipe in the direction of flow. Next, connect it to compatible 110mm underground drainage pipework. Make sure all joints remain clean, secure and correctly supported. Set the access top level with the intended finished surface. Also, protect the fitting from movement while completing the surrounding groundworks. Finally, keep the cover clear so maintenance teams can reach it when required. Do not install the rodding point in a trafficked area unless its confirmed load rating and installation method suit the expected load.

Smaller connection range	105–114mm outside diameter
Pipe compatibility	Compatible PVC drainage pipe
Body material	Flexible rubber
Clamp material	Stainless steel
Colour	Black
Application	Compatible non-pressure underground drainage

Check Your PVC Pipe Sizes

Measure the outside diameter of both PVC pipes before ordering. Do not choose this connector from the nominal pipe size alone because different PVC drainage systems can have different outside diameters. The larger PVC pipe must measure between 132mm and 142mm across its outside diameter. The smaller PVC pipe must measure between 105mm and 114mm. Do not use the connector if either pipe falls outside these ranges. Also, measure the plain pipe barrel rather than a socket, collar or enlarged fitting end.

Where Can You Use This PVC Pipe Connector?

Use this fitting for compatible underground PVC drainage repairs, extensions and alterations. For example, it can connect an existing larger outside-diameter PVC drain to modern 110mm PVC drainage pipework. The flexible body helps accommodate small differences in pipe alignment and outside diameter. In addition, the separate clamp bands allow installers to secure each connection correctly. This budget connector is intended for compatible gravity drainage systems. Do not use it on pressurised water, gas or other pressure pipework.

Installing the PVC Pipe Connector

First, clean the outside of both pipes. Remove dirt, grit, sharp edges and damaged material that could affect the connection. Next, slide the connector onto one pipe and position the second pipe. Centre the rubber connector across the joint and make sure both pipe ends sit fully beneath their clamp bands. Finally, tighten the stainless-steel clamps evenly with the correct tool. Check the alignment before completing the pipe bedding and backfill. Do not overtighten the clamps or leave the joint unsupported.
