With over a decade in mining equipment maintenance, I’ve seen generic seal packages fail consistently: their low-quality rubber lacks oil resistance and elasticity, hardening or cracking within months of use (even with light operation). This leads to frequent leaks and forced maintenance, disrupting production schedules. In contrast, this Seals package 101217449 is a genuine OEM part, engineered to strict standards: each seal uses a specialized oil-resistant rubber compound that retains flexibility even after long-term exposure to HC28’s hydraulic fluid and mining debris. Every seal’s size and shape are machined to match HC28’s component tolerances exactly—no “gap” that causes leaks, and no need for time-consuming modifications during installation.

Since seal wear varies by usage (e.g., heavier drilling increases wear rate), the “replace based on actual conditions” guideline ensures you avoid unnecessary replacements while preventing sudden failures. And with short delivery times (no 2-3 week waits like generic seal kits), you can restock quickly when leaks or wear appear—keeping your HC28 drills operational. Add in competitive pricing that beats many non-OEM options, and this Seals package 101217449 becomes an essential choice for mines prioritizing flexibility, reliability, and cost-efficiency. Whether you’re drilling coal, limestone, or metal ore, it keeps your HC28’s hydraulic system running smoothly—no matter the working conditions.
