John Guest JG Speedfit : Pack of 10 UNIVERSAL Suitable for central heating systems
The unique feature of the Speedfit concept, the ability to disconnect the fitting should you want to, means the Speedfit Stop End not only provides a leak proof seal, but can be readily removed to allow work to restart or to allow an extension to a system. Thus, the fitting is especially useful to allow water to be turned back on, overnight for instance, or if a job has to be interrupted for another reason.
Stop Ends are also useful when pressure testing a system before appliances are connected.
