The post 110mm Underground Drainage Double Socket Slip Coupler | Kayflow | BUG12 first appeared on Speedy Plastics Ltd.]]> 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.

The post 4″ PVC to PVC Budget Pipe Connector | Competa Drainage | CUGFCPP first appeared on Speedy Plastics Ltd.]]> 4″ PVC to PVC Budget Pipe Connector This PVC pipe connector joins compatible underground PVC drainage pipes with different outside diameters. It features a flexible black rubber body and two stainless-steel clamp bands that tighten independently around each pipe. The larger side covers an outside-diameter range of 132–142mm. Meanwhile, the smaller side covers 105–114mm. Therefore, customers must measure both pipes before ordering rather than relying only on a nominal 4-inch or 110mm description.

PVC Pipe Connector Features

  • Connects compatible PVC drainage pipes
  • Larger connection range of 132–142mm
  • Smaller connection range of 105–114mm
  • Suitable for connecting different PVC pipe outside diameters
  • Flexible black rubber body
  • Stainless-steel clamp at each end
  • Each clamp tightens independently
  • No solvent cement required
  • Useful for underground drainage repairs and alterations
  • Practical economy option for non-pressure 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.
