You shouldnt be going through them every night, do you use the brown or black ones. Both are good, but I've used the brown ones for the past year & 1/2 with no real problems. I get them from Bob at PT

I know where you can get some that will last 6months to a year, with heat. They are real exspensive, i think i paid $70.00 for 25 o-rings. I use to get them from simpson when they were in clearwater.They were bought out buy KEW and moved to Atlanta, I think? I have thier number somewhere, i will find it and let you known.They are the best i have found but for that price i think i will keep changing them out.......

Brown Ones Here , They Usually Last Around 3 To 4 Weeks

My guess is that the rest of the quick conenect is wornout and that is why you are going through them so fast. I usually can get a couple of weeks out of an o-ring, seldom less than a week.

cold water last for a long while but in all hot water conditins they go much quicker
The only O-rings that I go thru on a semi regular basis is the ones between the gun and the wand /surfacer.
The little bit of play in there is chewing them up, vs the heat. I now use a Mosmatic swivel on the end of the gun and it has extended the life of O-rings considerably. It also makes hose management much easier.

I use alot of heat and hardly ever change the others. It is that pivot point that kills them. Mosmatic gun swivels are ideal, look it up, http://www.dultmeier.com/search.asp 30051

Mr Allen is right , the constant grinding on the is wht is worse than anything else
O'ring problems
Here is what I have found.
1. Many people try and make the quick connect release better by using a lubricant such as WD40 or the like. When you do the life of the o'ring has been reduced to hours or days.
2. O'rings in the 'QC' between the gun and hose are generally the ones that wear out first. When you use the gun and lance as leverage to pull the hose you put the plug and coupler in a serious 'bind' and the tip of the plug digs into the o'ring. This can be eliminated by installing a 1' hose whip on the inlet side of the gun and then the "QC' on the end of that hose. Now when you connect the longer high pressure hose into the shorter high pressure hose and you use the Gun/Lance as leverage to pull the hose you will notice that the 'QCs' are pulling in-line with each other.
3. Although Viton is rated in the 400 degree range and most contractors run their machines at around 190-200 - when in introduce pressure into the equation Viton's high heat range becomes less of a factor in the longevity of the o'ring.
4. The ideal cleaning temperature when using chemicals is up to 160 degrees. Beyond that and you have reached the area of diminishing returns. Not only that but you equipment (from the coil out) will not last near as long as it will in the 160 (and lower) range. If you do not have a thermostat on you machine you can regulate the heat by going to a smaller burner nozzle. If you do not know how to do this call Paul Kassander at 877-351-1238.
Hope this helps.
