Symmetrical lug coupling — hosetail.
Symmetrical lug coupling — hosetail. Match lug designation, claw count, nominal end size and material; nominal hose size alone does not establish compatibility. Lug designations are retained as identifiers; no unit is guessed for an unlabelled lug number. Pressure requires exact construction confirmation: an aluminium6–8 bar note and a broader16 bar family claim must not be flattened into one rating.
