Description
This professional Type II plastic coupling is designed for secure and durable below ground pipe connections, providing a reliable joint between sections of pipe in drainage, sewer and water management systems. Manufactured from tough plastic and supplied with a multiple seal gasket, it delivers a tight, long‑lasting connection that helps prevent leaks and ground water ingress.
Available in a wide range of outside diameters, this coupling is ideal for new installations, repairs and alterations to existing underground pipework. Its versatile design and compact width options make it suitable for use in residential, commercial and light industrial applications where dependable below ground pipe joining is essential.
Product Features
- Professional Type II plastic coupling specifically engineered for below ground pipe connections.
- Multiple seal gasket system for a secure, watertight and gas‑tight joint between pipe sections.
- Available outside diameters from 40 mm, 50 mm, 63 mm, 75 mm and 90 mm, plus additional larger sizes to suit a variety of pipe systems.
- Compact coupling widths of 85 mm and 110 mm to accommodate different installation spaces and pipe diameters.
- Manufactured from robust, corrosion‑resistant plastic suitable for buried applications.
- Designed for compatibility with common underground drainage and service pipework.
- Smooth internal profile to help maintain flow and reduce the risk of blockages at the joint.
Key Features and Benefits
- Ensures leak‑resistant underground connections, reducing the risk of water loss, infiltration and ground contamination.
- Multiple seal gasket provides added security and tolerance for minor pipe misalignment or surface imperfections.
- Lightweight plastic construction makes handling and installation easier compared with metal alternatives.
- Corrosion and chemical resistance supports long service life in harsh buried environments.
- Wide size range allows one coupling family to be used across multiple pipe diameters, simplifying specification and stockholding.
- Quick to fit with standard tools, helping to minimise installation time and labour costs on site.

Frequently Asked Questions
Can this plastic coupling be used with different types of underground pipe?
The coupling is designed to be compatible with common below ground plastic pipe systems of the correct outside diameter. Always check the outside diameter of the pipe and ensure it matches the coupling size selected, and confirm suitability with system requirements before installation.
Is any special tooling required to install the coupling below ground?
No specialist tools are usually required. Installation typically involves cutting and preparing the pipe ends, cleaning the surfaces, and then fitting the coupling over the pipe with the multiple seal gasket correctly seated. Follow standard installation practices and any applicable site or regulatory guidelines.
Is the multiple seal gasket replaceable if it becomes damaged?
The multiple seal gasket is an integral part of achieving a secure, watertight joint. If the gasket appears damaged, worn or contaminated before or during installation, the coupling or gasket should be replaced to maintain performance and ensure a reliable seal.
