The Straight Adapter is a connector that joins two straight sections of tubing or pipes. It can have different end configurations, and in this case, it's designed to transition from an O-Ring Face Seal to a Straight Thread O-Ring. It allows for a transition between different types of hydraulic fittings or components, ensuring a secure and leak-free connection between the O-Ring Face Seal and the Straight Thread O-Ring components in the hydraulic system.Attributes:• O-Ring Face seals through the compression of the O-Ring while Straight Thread O-Ring seals when the threaded connection is tightened.• High-pressure applications to prevent leaks.• Direct and linear connections.Applications: The Straight Adapter is used to transfer hydraulic fluid in the fuel line. It a straight adapter is a fitting that enables a straight-line connection between hydraulic components. It does not change the direction of fluid flow but rather facilitates a direct and linear path.
