91E6-2712 Arm Cylinder Seal Kit — Product Overview

The 91E6-2712 Arm Cylinder Seal Kit is a precision aftermarket replacement for the Hyundai R130LC excavator. Designed for the arm (dipper) cylinder with 80mm rod and 115mm bore dimensions, this kit is manufactured to Hyundai OEM specifications using premium sealing materials etc.

The R130LC is a 13-ton class crawler excavator widely used in utility, landscaping, and light-to-medium construction applications. The arm cylinder generates the machine’s primary digging force by pulling the bucket through the cut — operating under high cyclic loads and constant exposure to abrasive soil, rock dust, and moisture. Seal failure results in arm drift, reduced digging power from internal oil bypass, and hydraulic oil contamination.

The 91E6-2712 kit uses high-grade polyurethane rod seals for maximum abrasion resistance in digging environments, PTFE backup rings for extrusion protection under peak breakout pressure, and NBR static seals etc. DJF Seals supplies this kit at factory-direct wholesale pricing.
