Guy's after doing months of testing I have had no trouble with the SuperTrap, I fully warranty them and will replace for free tested before it is sent... Festos work fine as long as you use 1/4" tubing I supply, allot of people try to use 6mm thinking it's 1/4 in. and an air leak will accure.. these problems I have run into ... I will replace the tank with a compression type fitting if you wish.. Please let's not forget how many BVM tanks have been recalled for leaks... I have over nine hundred of these tanks out in the field this year alone... I stand behind my products just like I have for the last 25 years... As for the black O-ring seal that is what seals the filter holder to the cap....
