Hydraulic rock drill O-ring (Part No. 5750531797) is a critical sealing component for mining, quarrying, and construction hydraulic rock drills. It forms airtight and watertight seals between hydraulic system components, preventing fluid leakage, air ingress, and dust contamination. The O-ring fits perfectly into hydraulic circuits, cylinder assemblies, and connection ports, ensuring stable power transmission even in extreme working conditions.
We make this O-ring to strict OEM specs, ensuring a perfect match with mainstream hydraulic rock drill models. It requires no on-site modification, allowing workers to replace worn seals directly, cut downtime, and lower maintenance costs.
The O-ring uses premium NBR or FKM rubber, resisting hydraulic oil, high temperatures (-40°C to 200°C), pressure up to 30 MPa, abrasion, and corrosion. It retains elasticity and sealing performance in harsh mining and quarrying environments.
Its precision cross-section and smooth surface ensure uniform contact pressure, blocking fluid leakage effectively. This protects pistons, cylinders, and valves from contamination, reducing wear on key parts and extending equipment service life by over 20%.
This O-ring (5750531797) suits diverse hydraulic rock drill applications:
- Mining: Seals underground hydraulic systems against high vibration and dust.
- Quarrying: Seals surface drill connection ports, withstanding outdoor weather and stone chips.
- Construction: Seals cylinder components for foundation and tunnel drilling.
- Maintenance: Serves as a direct OEM replacement part for drill overhauls.
Every O-ring undergoes multi-stage quality checks, including precision molding, dimensional measurement, hardness testing, and pressure sealing tests. It meets ISO 3601 and ASTM D1414 standards, ensuring consistent quality across all batches.
Consult our sales team to select NBR (general use) or FKM (high-temperature/chemical environments) based on your drill model and working conditions. We offer flexible MOQs, bulk purchase discounts, and fast global shipping to meet your project deadlines.
