6818255 Hydraulic Bucket Cylinder Seal Kit for Bobcat Excavator 337G / 337WG / 341G | Factory Wholesale
6818255 Bucket Cylinder Seal Kit — Product Overview
The 6818255 Bucket Cylinder Seal Kit is a heavy-duty aftermarket replacement for Bobcat 337G, 337WG, and 341G excavators. Designed for the bucket cylinder with 2-1/4″ rod and 3-1/2″ bore dimensions, this kit matches OEM cylinder specification 6818255.
The bucket cylinder on the 337G/341G platform endures the machine’s highest structural loads — from breakout forces during heavy excavation to shock loads when encountering rock, hardpan, and demolition debris. On 30-40+ ton class machines, bucket seal integrity directly impacts digging productivity, fuel efficiency (from internal oil bypass), and environmental compliance (external leakage).
The 6818255 kit uses high-grade polyurethane rod seals for maximum abrasion resistance in the bucket’s harsh operating environment, PTFE backup rings for extrusion protection during peak breakout pressure, and NBR static seals etc for reliable containment. DJF Seals supplies this kit at factory-direct wholesale pricing.
