Hydraulic Oil Bonded Seal Ring 2mm Thickness 4-60mm Inner Diameter 40MPa Pressure Resistance
Bonded seals effectively prevent oil and fuel leakage in high-pressure hydraulic systems through their unique metal washer and elastomeric ring construction.
Each bonded seal consists of a stainless steel metal washer with a nitrile rubber elastomeric ring securely bonded inside the diameter. The metal washer limits deformation and prevents over-compression of the elastomeric ring, ensuring reliable sealing performance under extreme conditions.
