Flexible Tap Connector 15mm x ½" x 500mm (3446G)

Hello JSD10, Yes, this includes the olive. Thank you for using Q&A

Hello, If your kitchen sink mixer tap is the deck mixer type, similar to our code 1371T, then it the hose connection will normally be 1/2" BSP male threads and these hoses will fit. If however it is a mono mixer tap, similar to our code 9385T, then it will normally have either M10 or M12 female threads in the base for the hose connections and will require the hoses with an M10 or M12 male thread, such as our codes 4565G and 5891G. Thank you for using Screwfix Q&A.

Hello NADS11, A ½" is approximately 12.5mm, M12 is therefore slightly smaller. Thank you for using Q&A SW

Hello, We have look into both these products and there specifications, and as can be seen there is nothing that separates the two. We did find that they are produced and imported by different foreign companies and that 3446G appears to be newer. If you email this enquiry to online@screwfix.com we can look into this further and find out if there is anything that separates these products performance wise. Thanks for using Q&A.
