No, in fact you shouldn’t use any other brand of seals, no matter which type of RV gate valve you have. All valve seals the RV industry are made specifically for the valves they are sold with. The Drain Master seals are special in that they are impregnated with graphite which lubricates the gate as it slides back and forth while opening and closing.
