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" The larger male end slots directly into the socket of standard tees, elbows, or valves, allowing you to convert any standard fitting into a reducing fitting instantly without adding extra pipe nipples.
