About Sandvik 880 779 09a Bonded seal
This sealing component prevents hydraulic fluid leakage and contamination ingress in the Sandvik DX700 hydraulic system. Located within the Rock drill, compromised seals lead to reduced drilling pressure, increased oil consumption, and potential damage to hydraulic pumps and valves.
This is an OEM-compatible aftermarket replacement part for the Sandvik DX700 (DX700). Also compatible with Tamrock branded equipment of the same model series. BK Drilling supplies this part with fast worldwide shipping and competitive pricing.
Frequently asked questions
What happens when a hydraulic seal fails?
A failed hydraulic seal causes fluid leakage, leading to reduced system pressure, loss of machine force and speed, increased oil consumption, environmental contamination, and potential damage to pumps and valves operating without adequate fluid supply.
How can I identify worn seals in my drilling equipment?
Signs of seal wear include visible fluid leaks around cylinders and connections, reduced hydraulic system pressure, slower machine movements, increased oil consumption, and contaminated hydraulic fluid appearing milky or discolored.
