The O-ring Kit M3057 is a seal replacement kit for the tekmar 3-Way and 4-Way Brass Mixing Valves from 1 1/2 inch through to 2 inch. The kit includes a small O-ring, a medium O-ring (indicated with a white paint mark) and a large O-ring. All of the O-rings are lubricated with silicone grease. These O-rings are needed if a valve shaft is leaking or to reseal after opening up for maintenance.
