F133, F137, and F139 Series Valves
Fumoto's F133, F137, and F139 Series Valves were designed to minimize the time it takes to drain all of the oil from an oil pan. Sizes are as follows: 12mm-1.25 threads (F133); 12mm-1.75 threads (F137 ), and 12mm-1.5 threads (F139 ). These are interchangeable with the F-103, F-107, and F-109 valves. The new valves have bodies that are 29% larger, with an oil outlet size nearly 60% larger than the previous versions. The company said this size upgrade will dramatically increase the rate of flow to expedite oil changes. The F133S, F137S, and F139S have a nipple 5 mm in length (suitable for attaching a hose connector and hose to direct the flow of oil), while the F133N, F137N, and F139N valves have a 15 mm nipple for direct hose attachment.
