FirstName LastName Posted: Dec 19, 2006 08:59 PM	i went to a hydrolic repair garage with a rebuild kit and had them match the orings. cost pennies each, dynasolve ruins them but for the price i replace them. also heard soaking gun in antifreeze when not in use doesnt let overspray stick, didnt work for me.

Do not boil the whole gun the teflon and orings in the gun will not take it.I use the boiling antifreeze to clean the mixing chambers and any other metal parts.Put some type of cover on the gun. wal-mart sacks work Or the heavy blue paper towels Will take some pictures of ours.A razor knife and a dremel with the stailes wire brush will keep it clean.email anytime elb@mtnhome.com
Trey Gibson Posted: Dec 20, 2006 08:12 AM	We have been looking for a place to get the o-rings matched but the shops we went to said they would have to make a cast and get them custom made. What exactly is a hydrolic repair garage?
FirstName LastName Posted: Dec 20, 2006 12:40 PM	its a shop where they fix hydrolic cylinders on loaders, cranes, etc. just bought 10 sets for $50
Trey Gibson Posted: Dec 20, 2006 02:03 PM	Do you know what the ID and cross section are of the o-rings. And what type of material did you get them in?
Posted: Dec 21, 2006 01:49 AM	i wrap my gunbody in a dynasolve soaked rag.. this goes in a large ziplock... leave overnite... brush off loosened debris or blow off with air.. protect your gun body from the overspray to start.. i use a 8" piece of 2" tubular stockinette..(medical supply house,,,about $9 for a 25 yd box) after assembling gun fluid section and attaching to gun i pull this stockinette onto the gun from the nose till it just goes to the end of the nose ring(?)...i then secure with electrical tape by wrapping,,winding towards the air cap to with in a 1/4" or so and wrapping back unto the ring allowing the stretch on the tape to be reduced so it lays down nice and doesnt curl...the stockinette is pulled back over the gun end and a small slot is cut to accomodate the safety knob and this helps keep the stockinette taunt while shooting. i fold the stockinette up to allow the gun to be coupled to the hose block,,then fold it back down over the manual valves protecting them too...sometimes the valve heads poke thru by days end but the drift on them is small... what are you doing with all those o-rings,, i just replaced my side seal orings after about a year of spraying with them... i replaced them as a sense of maintanance, not that they were leaking or worn...
FirstName LastName Posted: Dec 30, 2006 04:20 PM	what product are you using? seems like i go through side seal o-rings about avery 3-4 weeks. also have to breakdown my gun quite often also. tips?
Posted: Jan 06, 2007 11:31 AM	i tear the rig down daily,,i do not grease,,ever.. i use glycol ether (barsol) to soak parts overnite,,takes a little more effort to clean in the am than dynasol but doesnt soften/swell the rubber parts...also my screens dont clog with that gelatinous stuff,,,,so the last forever..i just blow em out..from the inside to the outside.... i use a dynasol soaked rag with the metal gun body and gun part wrapped and place in a large ziplock freezer bag....no rubber parts...blows off in the am for the most part... when spraying closed cells at a good rate of volume,,we sometimes change the chamber (actually we change out the fluid head) when we notice we are cleaning it more often,,,it gets a glaze that the drill bit doesnt remove and is prone to oclude at a faster rate...we can keep a good pattern with less effort...
Glenn Gamblin Posted: Jan 13, 2007 07:45 PM	I used to clean my gun daily, but I learned that the best way is to leave it alone. The more that you pull it apart, the more problems you have. The absolute best way to clean is to get a product from home depot called Klean Kutter Remover. It will be in the paint department. Don't mistake it for the adhesive remover or stripper. Wrap a plastic bag around your gun, dump the klean kutter in there and let it soak overnight. I then pressure wash it. When storing your gun, always make sure you trigger it a couple of times after shutting off your fluid valves.
Glenn Gamblin Posted: Jan 13, 2007 07:50 PM	There is a guy on ebay that sells them for 25 dollars.
Posted: Jan 13, 2007 10:12 PM	Glengamblin, could you give more details on the e-bay guy.
Glenn Gamblin Posted: Jan 14, 2007 12:51 AM	You can go into ebay and you can search for fusion o-rings. You can go to item 190054175857 by entering it in the search. He has them for the gap gun, fusion and probler. I used them when I used my fusion gun, but I got rid of it and went back to my gap pro.
Posted: Jan 15, 2007 07:51 AM	glenngamblin, you mention that you soak your gun overnight, then pressure clean in the morning. By pressure cleaning did you mean the outside of the gun or the internals of the gun. But, I would like to know if you mean that you pressure clean the internals of the gun is it with a pressure pot spray gun cleaning system like you can purchase off graco. But shouldnt you pressure clean the internals after use, to stop the iso from becoming hard inside the gun. I would like to know how you find the pressure pot does it mean that it saves you time from taking your gun apart and how often would you need to take your gun apart to clean it, if you where using the cleaning pot system every time you used your gun how often much gun cleaner would you use each time. thanks.
Glenn Gamblin Posted: Jan 15, 2007 08:17 PM	I don't use a pressure pot and I never take my gun apart, maybe once every two months to replace my side seal orings. I actually use a pressure washer to clean the overspray off. As far as the iso. reacting in the gun I have never had a problem. If you don't take the gun apart, moisture can't get to it so it is stable. I was afraid that water would get to it the first time I washed it but it never has caused a problem.
Michael Flander Posted: Feb 01, 2007 04:21 PM	The goal when it comes to gun maintenance is to have as little of it as possible. Ideally you want to have either 2 guns or an extra fluid head. That way when a gun goes down, you can swap it out quickly and continue on your way. You only make money when you are spraying. Regarding cleaner, of all the tried and true methods, a Product called Safety Strip is by far the best out there. It is a little on the spendy side, at $80 a gallon. But is reusable. When you need to clean out the fluid to reuse it, simply run it through a coffee filter or other filtering device. 1 gallon should last you for quite some time. It is also much safer to use compared to some of the harsher chemicals I have heard mentioned in this thread. You can contact me for more info and to purchase Safety Strip. Whatever you do, DO NOT use a waterbased solvent with isocyanate, the result could end up costing you more money. The O-Ring debate is one of the longer running debates when it comes to the Fusion Gun. I can put you in contact with many people who have tried every way possible and have had them work, and vice versa. The truth is, not many people are aware of proper cleaning techniques of the o-rings they are using, and that Graco offers bulk packs of individual o-rings(6 or more to a pack, and you can purchase the specific o-ring you are looking for). Again, contact me for more information, I will be glad to help. Lastly, Unless you plan on not using the gun for a length of time, it is HIGHLY recommend that you simply use the grease port on the gun to inject lithium grease into the gun instead of rebuilding the gun. Rebuilding the gun that often can cause premature wear on the parts and o-rings, and increases the risk for human error. All of which can lead to more down time and less money for you, the contractor. I am an equipment supplier, if you have any questions and/or need any parts regarding your Fusion/Reactor system, give me a call. I will help in any way I can.

Posted: Feb 28, 2007 06:52 PM	Hello, I'm about to get a fusion air purge. I've been using GX-7. I spray roof foam. What type do you spray? Erik
Timothy Sonney Posted: Mar 02, 2007 01:50 AM	We spray about 3 times a week with the Fusion AP gun, when we're done we grease the gun, thats about it.... about every 2-3 months we will to a complete teardown and cleaning.... we have had no problems with this method. we spray 2lb cc been running the same seals since Aug 2006
Posted: Mar 02, 2007 08:28 AM	can you be a little more specific about "greasing" the gun? thanks.
Michael Flander Posted: Mar 02, 2007 01:22 PM	The fusion gun has a grease port on it to allow you to inject lithium grease into the cavity where the material may contact air. It forces any remaining material out of the tip and seals it with the grease to keep the gun in good working condition for the next time you want to spray.

Aaron Scurlock Posted: Mar 05, 2007 05:50 PM	Where can I get the super stripper stuff? I assume it will work for cleaning polyure also?
