Brass Non-Return Valve Spring Check with Barb Tail

This brass non-return valve is designed to keep water moving in one direction, helping prevent backflow that can cause contamination, loss of prime or system damage. It’s a dependable choice for garden irrigation, plumbing and general fluid transfer where consistent flow direction matters.

Made from durable brass with an integrated spring check mechanism, it provides a positive closing action and long-lasting performance. The barbed hose tails grip flexible hose securely, while the female BSP threaded connection allows straightforward integration with compatible fittings.

Choose the correct size to match your hose and threaded connection, then install in the correct flow direction for best results. It suits a wide range of domestic and trade installations, including pump lines, water butts, irrigation runs and general pipework where backflow prevention is required.

For threaded joints, use PTFE tape to help achieve a leak-tight seal (sold separately). If you are using hose tails, securing the hose with suitable clips is recommended for a firm, reliable connection.
