This is one of those kits that you won't use it for months (or maybe years) but when you need it you will be so glad you have it !This is for air conditioning on cars , and as I work in a garage I cant remember how many times I needed a valve , or a rubber seal or lost a cap ! This kit would have been invaluable to me at the timeIn the kit you get a box of rubber air con seals , these are mainly used on the air con pipes and should be changed every time the pipes are removedThere are 270 seals ! so this should cover all eventuality'sYou also get a box of valves , these are where the air con is filled up from and yes they do leak , in the box you get a selection of valves approx seven different types and plus you get the all important valve key to remove and fit them !Last but not least you get a bag of spare air con pipe caps , these go where the filling valves are to protect themSo a great set and I would wholly recommend if you do any work on air con systems !!
