SANPING SEAL – Engineering Machinery High-End Seals – 17 Years Export Expertise
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. This seal kit replaces the previous part number 7196894 and is compatible with loader tilt cylinders, backhoe loader boom cylinders, and backhoe attachment boom cylinders .
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.

Kit Components Included
The 1543256C1 Seal Kit contains all necessary seals for a complete hydraulic cylinder rebuild:
● Rod Seals – Primary sealing element for the piston rod, preventing oil from leaking out
● Piston Seals – Seal between piston and cylinder bore, maintaining pressure across the piston
● Wiper Seals (Scrapers) – Remove contaminants from the rod during retraction, protecting internal seals
● O-Rings – Static sealing for end caps, glands, and other threaded connections
● Backup Rings – Prevent O-ring extrusion under high pressure
● Guide Rings (Wear Rings) – Provide radial support and prevent metal-to-metal contact
All components are manufactured with precise dimensional tolerances to ensure a perfect fit with original CASE cylinder components

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.
