Groco tri-flange seacock with field-reversible handle allows you to select the closed position orientation (clockwise or counterclockwise) that best suits your hull installation. The handle has a square hole to accept standard ratchets, help reach valves in difficult locations, and eases operation of hard to actuate valves. A drain plug on both sides allows easy, efficient winterization. Construction includes chrome-plated solid brass ball, stainless steel handle and hardware, and PTFE seats and seals. Port: 1-1/4" NPS (bottom), 1-1/4" NPT (top).
