Rated 5 out of 5 by from Reduce your leak headaches! These 15 -10mm internal reducers are fantastic! Difficult to find on online search as they are named as reducing set but once you use them you won't use anything else. Tighten till they click and job done, they seal to plipe. Simple and easy to use. Spot on! Wish I'd found these years ago!
