The Piston Pump O-Ring Seal prevents hydraulic fluid from escaping around internal moving parts. It fits into designated grooves within the pump housing or piston assembly and compresses during installation to form a secure seal. This seal helps maintain internal pressure, prevents fluid leakage, and protects against contamination.Attributes:• Withstands high pressure and hydraulic operating conditions.• Provides consistent sealing across a range of temperatures.• Prevents leakage that could damage surrounding components.Applications: The Piston Pump O-Ring Seal is used in hydraulic piston pumps, where it fits into seal grooves on pistons or housings to prevent fluid leakage and maintain system pressure during pump operation.
