110mm Straight Connector – The Reliable Standard for Soil and Drainage Systems

The Straight Coupler 110mm is a fundamental component for any residential or commercial drainage project. Whether you are extending a soil stack or laying a new underground sewer line, this connector provides a seamless bridge between pipes. At ECO Heat Shop, we supply the trade-standard hardware and drainage fittings required to build a safe, efficient, and long-lasting waste management system.

Designed for Performance and Longevity

Our 110mm couplers are engineered to be “slip-ready,” meaning they can be easily positioned even in cramped trenches. The interior of the coupler is smooth to prevent the buildup of debris and ensure an optimal flow rate, reducing the risk of blockages over time. Suitable for use both above ground (UV stabilized) and buried in the earth, this fitting is compatible with all standard 110mm (4-inch) PVC pipes commonly used across the UK.

ECO Heat Shop Tip: For the most sustainable and secure fit, always chamfer the end of the pipe and use a dedicated silicone lubricant on the seals before inserting. This prevents the rubber ring from dislodging or “rolling,” which is the most common cause of leaks in new drainage systems. Properly installed push-fit hardware can last for decades without maintenance, protecting your property’s structural integrity from water damage.
