Product Name: Cup Seal
Part No.: 3115336500
Model: UD391、UD391H
Weight: 2.17kg
This premium sealing component ensures leak-proof performance, maintains hydraulic system stability, and withstands extreme pressure in harsh mining environments.
The Cup Seal 3115336500 acts as a critical sealing core for hydraulic rock drills and follows strict OEM standards to tackle the extreme demands of mining, quarrying and tunneling operations. This heavy-duty cup seal offers outstanding wear resistance and oil compatibility, and forms a tight, reliable barrier that prevents hydraulic fluid leakage even under intense equipment vibration and continuous cyclic loading.
Advanced precision molding shapes the 3115336500 cup seal, which features a tailor-made structure to guarantee a perfect fit with hydraulic rock drill piston assemblies. Its high-grade elastomer material resists high temperatures, chemical corrosion and mechanical abrasion — common pain points that usually lead to premature seal failure and expensive equipment downtime.
This cup seal endures the harsh working conditions that hydraulic rock drills face during high-intensity drilling tasks, and eliminates the risk of system leaks that can disrupt construction schedules and damage key machine parts. Whether workers use it for regular maintenance, seal replacements, or emergency on-site repairs, it serves as a trustworthy solution for keeping drilling workflows efficient and safe.
It matches a broad range of hydraulic rock drill models, meets the strict quality criteria of the mining industry, and delivers long-lasting sealing performance. It cuts down maintenance frequency and reduces overall operational costs for mining enterprises and equipment maintenance service providers alike.
