The PBSL Group 110mm double socket slip coupling is an essential component for plumbing professionals and site contractors managing underground drainage systems. Designed specifically for repairing damaged pipe sections or simplifying new installations, these couplings allow for flexible positioning thanks to their internal stop-free design. While they are highly durable and compliant with industry standards, they require precise pipe preparation and proper lubrication to ensure a watertight seal during installation.

These couplings are specifically designed for underground drainage systems and comply with BS EN 1401-1, which governs underground gravity sewer and drainage systems.
No, lubricant is sold separately. The manufacturer recommends using SG100 lubricant for optimal seal performance.
The absence of a central stop (a 'slip' design) allows the coupling to slide fully onto a pipe, which is essential for repairing breaks without needing to move adjacent pipe sections.
The seals are designed to be permanent within the coupling. If a seal is damaged, it is recommended to replace the entire fitting.
These couplings are manufactured from high-quality PVC-u, common in drainage infrastructure for its durability and resistance to chemicals found in soil.
No, these are gravity drainage couplings and are not rated to withstand pressurized liquid systems.
Ensure the pipe end is properly chamfered and enough lubricant (SG100) has been applied to both the pipe and the inner seal.
Check that the pipe is cut square and is free of deep scratches or debris. Ensure the internal seal was not pinched or dislodged during the insertion process.
Verify that your pipe diameter is exactly 110mm and conforms to BS EN 1401-1 standards. Non-standard pipes may not create a proper seal.
To install these couplings effectively, begin by cleaning the pipe surface of any debris, soil, or grit. Once the pipe is cleaned, use a file or chamfering tool to create a smooth, beveled edge on the end of the pipe. Apply a thin, even coat of lubricant to the spigot end of the pipe and the internal seals of the coupling. Push the pipe into the coupling until the desired position is reached.
These couplings are compatible with most 110mm underground drainage pipes that conform to BS EN 1401-1 standards. To maintain the integrity of the drainage system, avoid exposing the fittings to extreme direct sunlight for extended periods during storage, and store them in a cool, dry place to prevent the pre-installed seals from hardening or degrading.
