Description
World American WA12105 is a manual air-tank drain valve with a 60″ pull cable for heavy-duty truck and trailer air-brake reservoirs. The 1/4″ NPT brass body and steel cable let drivers drain moisture and contaminants from the tank without crawling under the vehicle. Direct aftermarket replacement for Haldex 12105 / N3613AD, Phillips 12-820, Velvac 032082, Meritor R12105, Tectran 111160, and Tramec 35013.
