A 110mm straight coupler (also known as a double socket coupler) is the standard fitting used to extend a run of 4-inch pipe. It features a “female” socket at both ends, allowing two “male” pipe ends (spigots) to be joined together seamlessly. It is an indispensable component for extending soil vent pipes, connecting underground drainage lengths, or repairing damaged sections of a pipeline.
Leaking joints are the primary cause of subsidence and foul odors in residential drainage. Our straight coupler is manufactured with precision-moulded internal chambers that house heavy-duty EPDM rubber seals. These “captive” seals are designed to stay in place during installation, providing a permanent, flexible joint that can accommodate minor ground settling or thermal expansion without losing its integrity.
Whether you are working on a high-rise soil stack or an underground sewer run, this coupler is up to the task. It is manufactured from high-impact PVC-U, which is naturally resistant to the chemical corrosion found in domestic waste and the UV degradation from direct sunlight. The smooth internal bore ensures that there are no “lips” or edges to catch debris, maintaining a self-cleansing flow throughout the system.
Size: 110mm (Standard UK 4-Inch Pipework).
Connection: Double Socket (Push-fit with rubber ring seals).
Material: High-grade PVC-U.
Compliance: Meets BS EN 1401-1 (Underground) and BS EN 1329 (Soil & Waste) standards.
Installation Tip: For the best results, ensure the pipe ends are chamfered (bevelled) and use a silicone-based lubricant on the seals to ensure a smooth, deep insertion.
By choosing the 110mm Straight Coupler from ECO HEAT SHOP, you are ensuring a professional, trade-standard connection that will remain leak-free for decades.
