Wanders Stainless Female quick disconnect (aka quick connect) is built with with two Viton O-rings inside whereas other competing brands only have one. The double Viton rings insures a good seal and couples nicely with the Wanders Stainless Male 1/4 QD as well as the Brass Male 1/4 QD. Consider using Cool Connect Covers to insulate your hand from the heat when de-coupling.
We also suggest you add a “Cool Cuff Lube” to your QD order. It’s great for conditioning the O-rings on your QD’s as well as on a variety of maintenance repairs and installations such as Gator Crimps.
