Viton / FKM Upgrade O-Rings for Worker Swift

These 24×3 mm Viton/FKM O-Rings are a nice high quality upgrade for the Worker Swift. Viton/FKM O-rings have good wear resistance so will last longer under harsh conditions. These O-rings provide a very good seal. The O-rings are bigger than the stock O-rings, so it is possible there is a slight decline in performance due to increased resistance. We recommend lubrication with a thin oil to keep resistance as low as possible. Use all 3 O-rings, or only apply to pusher for best performance. Set of 3 O-rings.
