Push type fuel drain valves are close tolerance valves of simple design. These valves provide the most trouble-free operation of any other line of valves in the industry. Manufactured with an o-ring placed on the stem to seal against a flat seat on the body. This design eliminates an area where dirt can gather, thus putting an end to the main cause of fuel drain valve drip.
