Technical information

General technical guidance

The following explains this component family; it is not a specification or approval of the supplied WH variant.

Connection-system selection

British instantaneous, pin-lug and threaded connections are distinct interfaces. Match the coupling interface and the equipment-side thread separately; NST/NH, NPSH, NPSM and NPT labels must not be treated as interchangeable.

Confirm before ordering

Confirm the required size, connections, material and service conditions for the supplied configuration.
Use the confirmed manufacturer/model data for operating limits, compatibility and any required certification.
