DWV Threaded Access Cap – 100mm
Available Sizes: 100mm to 300mm

The DWV Threaded Access Cap is designed to provide secure and easy access to large inspection points in drainage systems. Commonly used with fittings such as rear access junctions, side access bends, and threaded couplings, this cap features a durable screw-on design with a rubber ring seal to ensure a watertight connection.

Note: These are not BSP threaded and are intended for DWV fittings only.
