The 110mm Push-Fit Screwed Access Cap (Black) is a heavy-duty closure component designed to seal the threaded inspection port on 110mm black soil system access fittings, such as access pipes and inspection bends. It provides a secure, removable barrier that allows plumbers and maintenance personnel to access the drainage stack for rodding and testing while maintaining a tight, gastight seal during normal daily operation.
 
Featuring a robust screw thread and an integrated rubber sealing gasket, the cap screws firmly down onto the matching collar of the access fitting. This compression seal prevents the escape of foul sewer gases and wastewater under backpressure while remaining simple to unscrew with standard tools when routine inspection or blockage clearance is required.
 
Manufactured from durable, UV-stabilized, high-impact uPVC in compliance with UK standards (BS EN 1329-1), the black finish coordinates cleanly with external black soil and vent systems. It serves as an essential component for maintaining the accessibility and structural integrity of drainage networks in accordance with UK Building Regulations (Approved Document H).
