| | Quality counts at Circle Seal Controls — and it always has. Reliable products and responsive service that set industry standards are the cornerstones of our business. As a result, we welcome each new program as an opportunity to move these bench marks of excellence ever forward.
Behind each Circle Seal Controls' product is a heritage of excellence dating back to 1947 when the company was founded as James-Pond-Clark. The fledgling firm developed and marketed its first innovation-a check valve that utilized a floating O-ring to provide a dead-tight seal. Shortly thereafter, the company's problem-solving skills came to the aid of the aircraft industry with a zero-leak check valve for fuel systems. | |
