Flexible End Cap 155mm–165mm

The flexible end cap 155mm–165mm is a practical drainage fitting used to close off the end of a pipe run and prevent water, debris and soil from entering or escaping. Its flexible design allows it to fit pipes with outer diameters between approximately 155mm and 165mm, making it suitable for a range of underground drainage layouts.

Made from a robust, flexible rubber body and fitted with a secure steel clamp, this end cap provides a reliable and watertight closure. The flexible material can adapt to slight irregularities in pipe surface and alignment, ensuring a strong seal even in less than perfect conditions.

Performance & Durability

This flexible end cap is designed for durable performance in underground environments. The rubber body resists moisture, ground movement and temperature changes, ensuring a long‑lasting watertight seal. The secure steel clamp reinforces the joint, helping to prevent leaks under typical drainage pressures.

Because it adapts to slight variations in pipe size and surface finishes, the end cap is often used where a neat and secure termination is required in pipe runs, whether for a permanent closure or temporary testing purposes.

Installation

Before fitting, ensure the pipe end is clean and cut square. Slide the flexible end cap over the pipe and position the clamp band evenly around the pipe surface. Tighten the clamp band securely to create a watertight seal in accordance with current drainage practices.
