Flomasta End Feed Fitting Reducers F 10mm x M 15mm 2 Pack (77635)

Hi Fflint - both products have 10mm female ends for the insertion of 10mm pipe. However, 92202 has a larger female 15mm end for the insertion of 15mm pipe. 77635 has the smaller male 15mm end that will fit into a 15mm fitting. Not done it myself, but I've seen 77635 used instead of a reducing set (70435) to fit 10mm pipe into a compression fitting or radiator valve. Some care might be required in positioning the reducer in the correct position to ensure the olive sits appropriately on the fitting.

Hi Bobalong - yes, you are correct. This item (77635) has a 15mm male end that will fit into a 15mm end feed fitting and, although I've never done it, could potentially be used in a 15mm compression fitting, or radiator valve as a 15mm to 10mm reducer (I prefer to use a reducing set 70435). (Be aware there is another similar item (92202) that has the female 15mm within which 15mm pipe can be inserted.
