This listing is for a Pack of 1 Being a "fitting reducer" this cannot be used directly onto 35mm pipe but must be inserted into a 35mm pipe fitting such as a coupling or an elbow. 28mm pipe is inserted directly into the other end of the reducer without the need for a 28mm fitting. Should you require a fitting where the two different size pipes are inserted into the reducer, you should purchase the appropriate sized "reducing coupling" Straightforward to install, requiring only cleaning of the pipe ends and heating with a torch to create a secure and leak-free connection. The solder joints in solder ring fittings are factory-applied, ensuring consistent quality and reliability across all fittings, reducing the risk of installation errors or leaks. Solder ring fittings provide a tight and durable seal between pipes, minimizing the risk of leaks and water damage in plumbing systems., Manufacturer: Cubralco
