Jerry 24 Report post Posted February 8, 2012 buna is the cheap low-temp version.. go for Viton, and less DOWNTIME. Eh? I have a HUGE variety of o-rings and back-up rings ..and pipe fittings variety too. Share this post Link to post Share on other sites
Douglas Hicks 128 Report post Posted February 8, 2012 The only place I use quick disconnects is nozzle/wand. Hoses, and all other connections I use the twist locks. I get mine from Delco/Rahsco/Power Wash. But I expect other suppliers who advertise here also have the twist locks. Share this post Link to post Share on other sites
Badzuk 16 Report post Posted February 9, 2012 Viton o-rings are 7x more expensive, but I'm considering buying some to see if they hold up any better behind the turbo tips. It seems that the vibration from the turbo tips is rapidly eating o-rings, but I really don't think Viton would hold up better, but I'm probably going to give them a try. I found that I have much fewer pump and unloader problems when I keep a good supply of o-rings in each truck. It is amazing how much extra wear and tear a leaky o-ring puts on a machine...

Jerry 24 Report post Posted February 9, 2012 7 times more expensive to a total additional cost of 35 cents.. ..saving you 15 to 45 minutes, and frustration.. whilst the customer watches you fumble through a rusty tool box.. Hmmm.. Viton is not only higher-temp-rated, it is more abrasion resistant ! About the Twist-Fast couplers.. I like 'em, they ARE more reliable, I should recommend 'em more often, ..certainly on 4000psi+ and 200degr.F+ systems I will add that point to my Pressure Washer "Bullet-Proofing" class. :{) Share this post Link to post Share on other sites
