*Warning* to those with an EDC and plastic/polycarbonate water trap

I have read before about the oils that are passed through EDC's not being very compatable with the polycarbonate bowls of some water traps. It breaks them down over time.

Yesterday I exprierienced this for myself. My truck was parked at work all day in the sun (90* outside) and I had about 180psi in the tank. I came out after work and noticed I had 0 psi in the tank. When I got out I saw pieces of the water trap everywhere. It exploded! I don't know why it didn't just crack and leak but looking at the pictures, you can see the mes it made. The tabs that held the metal shield on were all bent too. This was on my truck for about 1.5 years. I bought a replacement to get the truck home but will be finding a metal one soon.

Check it out.

the same thing for oil catch cans, guys are going out buying compressor air/water separators and they are not designed for this type of use! I wish you well on the fix and all. Love the blazer man.

Re: *Warning* to those with an EDC and plastic/polycarbonate water trap

We suggest the Rockstar ones be mounted as far away from the EDC as possible and havent had any trouble with them yet, but with this temperature well over the 100's I know its gonna be tough on all components

To correct Andy, we don't recommend they be used with an EDC, but if you are going to use them with an EDC, placing them as far away as possible will prolong the life. No matter the brand, over time the heat will break down a poly carbonate bowl. Thicker bowls will last longer, but they will fail eventually

Re: *Warning* to those with an EDC and plastic/polycarbonate water trap

Just had this happen to me with mine... Rockstar 1/2" trap

Was gonna call WayLayed to see if there is any kind of warranty on it but it sounds like probably not. My tank stays at 200 and this morning all of a sudden there's a bang/hiss sound like a gunshot. I immediately knew it was my truck but thought it was a bag blown (which threw me for a total loop because I have Slam bags and they don't rub or anything). Turns out the bowl has a huge crack down one whole side of it

Ando or Dirty... is there anything you guys can do about this? I do have an EDC but I have 6 feet of braided stainless line plus another 4-6 feet of regular airline before the trap, plus my truck has been lifted for over a month and a half and the compressor has maybe ran once every other week since my tank holds air and I don't drop it. So the actual fail today was most likely not related to excessive heat

Re: *Warning* to those with an EDC and plastic/polycarbonate water trap

i have an SMC one under the hood of mine, the one that actually came with the airlift EDC kit.

It says clearly on the side, max pressure 145psi.

I have a 135 psi pressure switch on mine, the EDC kit has been on the truck since like 2003. same water/oil trap, same bowl.

Maybe you guys are running too much pressure through yours? just a thought.

Re: *Warning* to those with an EDC and plastic/polycarbonate water trap

From what I found it doesn't seem that the SMC one uses a Polycarbonate bowl, but one made of either glass (doubt it) or some other type of plastic.

Either way, I'm sure it's a combination of the heat, pressure, and possibly reactive elements within the oil that cause the Poly bowls to fail

Best bet is to just get an all-metal one. The Milton 1020-8 that J Drummond Service Inc recommended seems to be the best option

Re: *Warning* to those with an EDC and plastic/polycarbonate water trap

I went to the K Tool show last year after shopping for a water trap that was rated at 200 psi... The traps rated for that kind of pressure are well into the hundreds of dollars range and I didn't want to spend that. The guy at the Devil Biss booth recommended that I check out the Milton booth so I did. I spoke to the rep and he recommended their 1020-8, die cast aluminum bowl and told me that the pressure rating of 150psi only pertained to ones produced with a site glass. I ordered mine for around $35. In my eyes - die cast aluminum > poly/glass ability to stand up to heat/cold/oil... just my opinion... it's the trap to use.

Re: *Warning* to those with an EDC and plastic/polycarbonate water trap

My pressure switch comes on at 160 and below and kicks off at 190.. so maybe I shouldn't get a water trap unless I find one that can handle the pressure

I believe they still have a plastic bowl on the inside of the cup. I may be mistaken.
