Description
The 4 Inch Internal Push Fit Flexible Coupling 95-100mm is designed to connect and repair 4 inch drainage pipes internally within existing pipe runs. The 4 Inch Internal Push Fit Flexible Coupling 95-100mm provides a secure internal joint where external couplings cannot be used due to restricted access.
4 Inch Internal Push Fit Flexible Coupling 95-100mm Installation & Use
The 4 Inch Internal Push Fit Flexible Coupling 95-100mm is manufactured from durable elastomeric rubber with stainless steel reinforcement rings for long-term underground and drainage use. It is designed for internal insertion into pipe ends to create a watertight seal between 95mm and 100mm internal diameter pipes.
The internal push fit design allows the coupling to be inserted directly into the pipe bore, making it ideal for repair work, pipe relining connections, and restricted access installations. Once fitted, it expands to create a tight seal against the internal pipe wall, maintaining joint integrity without the need for excavation or external clamps.
This type of coupling is commonly used in underground drainage repairs, clay to plastic pipe transitions, and maintenance work where pipe movement is limited. It helps restore continuity in damaged pipe sections while maintaining flow performance.
The smooth internal profile supports consistent foul and surface water flow while minimising turbulence within the pipe system.
Compatibility: The 4 Inch Internal Push Fit Flexible Coupling 95-100mm is compatible with 4 inch (approximately 110mm) underground drainage pipes including PVC and clay pipe systems commonly used in UK drainage installations.
