"My old Boss Green had gone hard so bought this. Easy to apply although a bit messy like all of these things. It has worked well on everything used for so far - compression joints and pump gate valve. Although quite expensive there is a lot in the tin."
"Just used this product after spending years using PTF tape. Apply once and done... no leaks. Just fitted a central heating filter and was dreading putting new compression joints in as always hit and miss with leaks and the pain of putting PTF on in tight spots. After reading reviews I thought I would give this product a try. Well works first time no leaks and easy to apply also no PTF on display and easy to wipe off excess after application and use."
