Please thoroughly read the instructions prior to operating the connector. The
Connectors are designed to provide a safe, reliable leak-tight seal and connection when properly
maintained and operated.
The connector is designed to mate with a specific application. Verify the application prior

to the introduction of pressure or processing. Use only in a safe environment. Safety chains
and guards are recommended for all applications.
Connectors are NOT designed for permanent connections and are for temporary
•
connections only. Inadvertent loosening and loss of media may result when used as a
permanent connection.
Connectors are not internally valved and will not prevent loss of media when disconnected.
•
DO NOT EXCEED pressure rating as marked on connector or corresponding literature.
•
Operating pressure rating based on tests using NPTF threads to (SAE J476a Dryseal
Specifications) of cold drawn steel. Material or thread deviations may reduce working
pressure and should be verified by test.
