What materials is the ISO-B PVC Quick-Connector Socket Plug, Type HK made from and is it compatible with standard HANSEN quick coupling sockets?

The ISO-B PVC Quick-Connector Socket Plug, Type HK is made from durable PVC (polyvinyl chloride), offering a lightweight yet robust seal to protect hydraulic connections from dust, dirt and other contaminants. It is specifically designed for the ISO-B standard HANSEN quick coupling socket, so it provides a precise fit and secure protection when the coupling is not in use, making it compatible with standard HANSEN quick coupling sockets that conform to the ISO-B specification.

Can the ISO-B PVC Quick-Connector Socket Plug, Type HK withstand exposure to hydraulic fluids and chemicals commonly used in industrial environments?

The ISO-B PVC Quick-Connector Socket Plug, Type HK provides effective protection against dust, dirt and contaminants but is made of PVC, which has limited chemical resistance compared with specialist elastomers or metal plugs. PVC resists many common hydraulic fluids (mineral‑oil based hydraulic oils) and water‑glycol fluids for typical short‑term exposure and sealing at ambient temperatures. However, prolonged contact with aggressive fluids (phosphate esters, some synthetic esters, polyglycols, strong solvents, ketones, and certain hydraulic additives) or high temperatures can soften, swell or degrade PVC, compromising the seal and durability. Recommendation: for general industrial use with standard mineral‑oil hydraulic fluids the ISO-B PVC Quick-Connector Socket Plug, Type HK is suitable as a protective dust cap. For prolonged immersion, exposure to aggressive/modern synthetic hydraulic fluids, or elevated temperatures, verify compatibility with the specific fluid manufacturer or select a plug material rated for chemical resistance (e.g., nitrile, Viton/FKM, PTFE) to ensure long‑term reliability.
