Mepco (Dunham Bush) D2488 Trap 319847-401 and an open circuit whenThe Mepco (Dunham Bush) D2488 Trap is a 3 4 inch thermostatic steam trap designed for precision condensate management in low pressure steam heating systems. Specifically engineered with a 2E AP angle pattern, this trap is a direct, identical replacement for the 2E AP radiator trap. It features a rugged brass body and a thermostatic bellows element that maintains high sensitivity, ensuring effective air and non condensable gas removal while preventing
