Quick disconnect, in-line couplings make replacement of disposable water filter connections quick and easy, and provide many advantages over standard water filter connections. Colder couplings are designed for countertop, under-the-sink and ice-maker applications – for both OEM and end-user. They have a higher degree of reliability and are easier to use. Colder couplings also feature integral shutoff valves that instantly stop the water flow; no need to turn off the water pressure or drain the lines, saving time and eliminating spills. The use of a Colder quick disconnect also eliminates the need for tools and the resulting potential for damage or costly leak points. Colder couplings simplify water filter replacement, giving consumers incentive to adhere to a regular maintenance schedule, which in turn can increase OEM sales.
