We make our seals, washer & pump leather in house & can make most stove, lamp & blowlamp washers. If we don't list it please let us have the dimensions & we'll see what we can do! No minimum order. We have made washers for all kinds of items. Our latest custom order is for tiny burner washers for the old & rare Comet No:6, an old Swedish pre WWI stove. Made from our standard gasket material. Please drop me a message if you need any washers made.
