Over the years I have bought couplers and plugs from various stores, they are all made abroad, usually in China and they are all breathable. Some leak all the time and others only leak when the slightest force is applied to the clutch. These connectors do not leak, are a secure fit and are a quality product. At Revain prices they cost no more than leaky ones, if you look at them then you probably want/need new ones, just do it, you won't regret it. Edit: 2014-11-08 Still holding up with no air leaks. I take better care of this set of hookups than others I've had over the years. I don't leave tools attached to the hitch when not in use, I've never done this before, I always left, usually by the end of the day they had a blowgun attached, I'm pretty sure that didn't help. cheapest clutches.
