Gasket 15191708 High-Temperature Resistant NBR Rubber Gasket for Hydraulic Rock Drills

High-Temperature Resistant NBR Rubber Gasket for Hydraulic Rock Drills
Engineered for extreme underground mining conditions, this gasket ensures reliable sealing in high-vibration hydraulic rock drill applications. Constructed from Nitrile Butadiene Rubber (NBR) with a zinc-plated steel reinforcement ring, it withstands continuous dynamic loads up to 25 bar while resisting oil and abrasion in harsh environments .

Technical Specifications & Design
The gasket features a 60 mm inner diameter (ISO 3601 tolerance) and 85 mm outer diameter, designed for secure mounting in hydraulic cylinder assemblies and drill rig components. Its Shore A 70 hardness provides optimal balance between flexibility and structural integrity, reducing the risk of extrusion under high pressure . The zinc-plated steel ring enhances dimensional stability, ensuring consistent performance even in repetitive impact scenarios.
