Start with the size
Share the inside diameter, required length and the existing hose marking where available. A clear photo of both ends helps identify the connection.
Describe the operating conditions
Include the medium, working pressure, peak pressure and operating temperature. Mention whether the hose will be used for suction or delivery.
Confirm the connections
Provide thread type, fitting size and end orientation. Do not assume that visually similar threads are interchangeable.
Request a verified match
Ask for the manufacturer specification and confirm compatibility before ordering or installing. Selection should be checked by a competent person.
