The Straight Thread O-Ring Plug is used to seal straight-thread hydraulic or fuel system ports using an integrated elastomeric O-ring that ensures pressure-tight sealing. It is used to close off unused or service-access connections during maintenance or testing. It offers strong torque resistance and maintains leak prevention in static installations, helping to avoid fluid loss and external contamination during service.Attributes:• Seals unused or service ports in hydraulic valve assemblies.• Maintains internal fluid pressure and prevents leakage.• Enables directional flow control in hydraulic circuits.• Provides a secure and reliable fit under pressure.Applications: The Straight Thread O-Ring Plug is used in hydraulic valve assemblies of equipment to seal off specific fluid channels, maintaining pressure and ensuring proper control of hydraulic fluid direction and flow during operation.
