1. Caterpillar-Grade Material Selection
Primary Seals: 3240356, 3240357, and 3240358 feature a proprietary fluoroelastomer (FKM) compound blended with aramid fibers. This material combination delivers 60% higher wear resistance than standard FKM seals, while withstanding the high-pressure fluctuations common in Cat hydraulic systems.
Wiper Seals & Backup Components: Each kit includes dual-lip nitrile rubber (NBR) wiper seals with a polyurethane coating—exclusive to 3240356, 3240357, and 3240358—that blocks 99.8% of dust, dirt, and moisture. High-strength POM (Polyoxymethylene) backup rings prevent seal extrusion, even under Cat’s maximum operating pressure.
Corrosion & Chemical Resistance: All metal parts in 3240356, 3240357, and 3240358 are treated with Caterpillar’s signature zinc-chromate plating, providing 12x better corrosion protection than industry-standard coatings—ideal for machines operating in coastal or chemical-exposed environments.

3. Caterpillar Machine Compatibility
Excavator Fitment: 3240356, 3240357, and 3240358 are fully compatible with Cat excavator models including 320 GC, 330 GC, and 349 GC. 3240356 is optimized for boom cylinders (handling high lateral loads), 3240357 for arm cylinders (requiring precise movement), and 3240358 for bucket cylinders (exposed to heavy impact).
Loader Fitment: As dedicated C.A.T CYLINDER SEAL KIT LOADER solutions, 3240356, 3240357, and 3240358 excel in Cat loaders like 930M, 950M, and 980M. 3240356 suits lift cylinders (supporting heavy payloads), 3240357 for tilt cylinders (frequent positioning), and 3240358 for auxiliary cylinders (e.g., quick couplers).
OEM Precision: Every component in 3240356, 3240357, and 3240358 is manufactured to Cat’s dimensional tolerances (±0.015mm), eliminating fitment issues and ensuring a leak-free seal—critical for maintaining Cat’s factory-set performance.
