This flexible self-sealing valve is designed for 40mm waste pipe applications in domestic and light commercial plumbing systems. The unit forms an air-tight seal without the need for a traditional water trap, helping to prevent the ingress of odours while maintaining efficient drainage.
Suitable for use in confined spaces or beneath sinks and appliances where traditional traps are impractical, it offers a straightforward installation process. The white finish blends with most standard pipework, making it a practical choice for new installations or repairs.
