Features:	ARGUS ISO 7241-1 series “B” quick release couplings are used for quick coupling and uncoupling of hydraulic lines. During the coupling action in zero or low pressure ranges, valves that release or block the flow are automatically activated. The QB-ISO-B quick release coupling, formed by the coupling plug and the coupling socket, is connected by pushing on a sleeve. This guarantees a flush connection between the two coupling halves.
Construction:	Galvanized steel with hardened parts subject to wear. NBR O-rings. Thermoplastic dust cap and dust plug. ARGUS couplings feature a chrome-III zinc plating with a long lasting resistance to oxidation (TOP COAT, patented).
Application:	Suitable for liquid lines with mineral oil-based hydraulic fluids to din 51524 T1+T2.
Specifications:	ISO 7241 B
Temperature range:	-4F (-20C) to +212F (+100C)
Note:	Rated flow / pressure drop compliant with ISO 7241-1 standard.
