Part# ha91016 tactair pcp universal air filter.just got one today installed on fill line between tank and compressor,just an additional filter to catch any remaining moisture before the air enters the tank.well started the fill and at 3600psi the o-ring blew right out of the fitting where it screws together.scared the crap out of me.no damage to anything,except the o-ring.not sure now if I'm safe to use this filter.sure got my attention.when it blew it made my compressor hiccup and cough till i got things shut down.removed the filter and completed my tank fill to 4000 psi that's on my 98cu.ft. tank.just a heads up.be careful

For the o ring to be blown out ,there must be a significant gap. Was the cap of the filter screwed on tightly ? It only need to be hand tight usually

I'm not familiar with this branded filter but I know from experience with other high- pressure filters that the cap must be tight with no gap. When screwing the cap on, lightly lube the Oring and screw the cap down and when you feel the Oring, gently screw it back and forth until the cap is hand tight. If you haven't pinched the Oring, there should be no gap. At 2-300 bar, an Oring can squeeze through a very small slot.

check out hatsan usa .com i was looking at the lightning air compressor.i have the air venturi compressor,any way saw the filter there supposedly for the compressor.i had opened the filter to check that it was completely assembled.the o-ring was dry,lubed with silicone o-ring grease.reassembled the filter and hand tightened very snug.I'm sure that this is from China,no markings or manufacturing name.does come with 2 extra o-rings along with extra filter material.while i checked the threads they seem rough at the start where the o-ring should seat.it screws together tightly,at least on the outside of the body.it looks flush when put together.it appears to be brass not alodine aluminum.

I was looking at something like this on amazon and it started to make me wonder how safe theses things are? We have no idea of quality control and long term testing. We put our trust into a $26 peice of aluminum from a foreign country with known quality control issues and then put 4500psi into it while standing nearby waiting for it to finish filling our vessels. It is kinda scary when you really think about it. Thank God you didnt get hurt. Thanks for posting this to keep us mindful.

Well for me after a 20 year career in aviation,keeping those big birds flying.lots of people onboard.they do things differently.i mean take the hydraulic systems,they operate at 3000psi fluid pressure.all the fittings with o-rings are backed with a Teflon ring on both sides of the o-ring to prevent o-ring blow out and leaks.just wondering why they are not used with these high pressure pneumatic's?shouldn't this be used here also.I'm not the engineer,just a mechanic.the Teflon backing rings always replaced when doing filter changes along with the o-rings.

Yea I did this on my inline filter on my Davv compressor. I pull the tampon out after evey use to dry any moisture and when I reassembled it I didnt tighten it down. Scared the living you know what out of me. My oring emerged undamaged and a little silicon grease on it and double checking the tightness has made this a one time occurence
