The 7135555 Seal Kit is a high-quality replacement seal kit designed for BOBCAT skid steer loaders and compact track loaders. Manufactured by SANPING SEAL, this kit includes all necessary seals, O-rings, and wipers required for hydraulic cylinder repair.
The 7135555 Seal Kit is specifically designed for use in BOBCAT skid steer loaders and compact track loaders. This OEM replacement part number is widely used across multiple BOBCAT model families, including the 700 and 800 series skid steers, S series loaders, and T series compact track loaders.
Hydraulic cylinders are critical components responsible for boom lift, bucket tilt, and loader arm functions. Over time, seals wear out due to heat, pressure cycles, contamination, and normal aging. When seals fail, hydraulic oil leaks, performance drops, and costly downtime begins.
Our 7135555 Seal Kit provides a complete solution. Instead of sourcing individual seals from different suppliers, you get everything in one box – precisely manufactured to meet or exceed OEM specifications. Every component is made from high-grade NBR material, chosen for its excellent compatibility with hydraulic oils, its heat resistance, and its durability under demanding working conditions.

Product Features
1. OEM Fit and Compatibility
The 1543256C1 Seal Kit is designed to match original CASE specifications for 1-1/2" rod and 3" bore hydraulic cylinders . All dimensions, materials, and performance characteristics are verified against OEM standards.
2. Premium NBR Material
We use only high-grade NBR (Nitrile Butadiene Rubber) for our seal kits. NBR offers outstanding resistance to mineral oil-based hydraulic fluids, excellent abrasion resistance, good tensile strength, and stable performance across a wide temperature range (-35°C to 120°C).
3. Complete All-in-One Kit
No need to search for individual seals or order from multiple suppliers. The 1543256C1 includes every seal required for a full cylinder overhaul, saving time and reducing ordering errors .
4. Strict Quality Control
Each batch undergoes two rounds of quality verification: pre-production sample testing before mass production, and final inspection before shipment.
5. Cost-Effective Alternative
OEM CASE seal kits can be expensive. The 1543256C1 offers comparable quality and performance at a significantly lower price point.
6. Extended Service Life
Field data from customers shows that our seal kits typically last 10-12 months in demanding conditions, compared to 2-3 months for generic, low-quality alternatives.
