Saf-Air Products

Saf-Air Products makes aircraft fuel and oil drain valves in Garden City, Michigan. The company says it has made quality products for the aviation industry since 1959. It describes itself as a family owned business that has been passed down from generation to generation.

The business started in a family garage. Today it runs a machine shop in Garden City. The company says it does all of its manufacturing on CNC lathes. It keeps designing and testing new drain valves, and it says it has patents on some of its valves.

The push type fuel drain valves are close tolerance valves. An o-ring on the stem seals against a flat seat, which removes the area where dirt can collect. The valves use Viton o-rings and can be rebuilt. They come in brass, and the push type valves are also available in stainless steel for salt water and agricultural use.

The flush fuel drain valves are designed as a replacement for a common flush valve line. They can be rebuilt by removing a C clip. Specialty fuel drain valves include lock open styles, and a bladder tank system is also offered. The company says it custom manufactures valves for specific applications.

Oil drain valves are another product line. The lock open and two piece designs are covered by a US patent granted in 1995. The design covers most aviation engines. The valves can be rebuilt with replacement kits. It also offers AN adapters, banjo bolt adapters and oil drain adapters for several engine makers.

The company says it works with original equipment manufacturers that use its valves in their aircraft. It sells through distributors and ships worldwide. It has a cross reference page, an approvals page and a distributor finder.

Recent additions include a fuel drain for Beechcraft airplanes, a fuel drain approved for Fairchild Metro airplanes, and a drain for the Socata TB20. A new oil valve and adapter assembly replaces the AN nut.
