Compression fittings create a leak-tight mechanical connection to copper, aluminum, brass, and compatible plastic tubing without soldering, brazing, or special tools. A ferrule (sleeve) is compressed against the tubing OD as the nut is tightened, forming a permanent pressure seal rated for water, oil, gas, and most process fluids. Compression fittings are the dominant connection method in HVAC refrigerant lines, residential gas appliance connections, instrument tubing, and light industrial process piping.
