Connect air or coolant pipes much more quickly and more securely than with hoses and hose clamps! These Quick Disconnect Couplings use spring retainer clips that are easily installed or removed by hand -- no tools required. Just weld the male ferrules to the ends of your aluminum tubes wherever you need an easily-operated connection. The double O-ring seals have been tested by an independent laboratory to be leak-free at a misalignment angle of 3 degrees per side under pressures up to 125psi! These three-piece kits are ideal for very tight installations and since they utilize two male ferrules, they allow up to 6 degrees of misalignment. Each kit includes two male ferrules, a female sleeve, and two spring retainer clips. (Each kit requires 4 O-rings, sold separately.)

"... [We] beat the snot out of them. After countless dyno pulls and a day at the track, we experienced zero failures. The QDCs even outlasted a blown head gasket." -- DSport Magazine, Jan '09
