As part of a redesign, STAUFF offers the QRC-HI screw-to-connect coupling for pressures up to 720 bar with a highly effective, zinc-nickel-based corrosion protection coating. <\/p>\n\n\n\n

Hydraulic manual pumps can provide pressure levels of several hundred bar. For this and for other areas of application, e.g. in rescue hydraulics, STAUFF has a screw-to-connect coupling in its extensive range which was developed especially for very high operating pressures. The QRC-HI series is available in nominal sizes from DN 6.3 to DN 10 and is suitable for pressures up to 720 bar and rated flows up to 20 l\/min (each depending on the nominal size). A poppet valve is used for opening and closing. alternatively, the user can choose a version with a ball valve (QRC-HIB series). <\/p>\n\n\n\n

The latest, revised version of these screw-to-connect couplings differs from the previous series in an improved corrosion protection, among other things. The couplings are now coated with the zinc-nickel corrosion protection which has already proven successful in the STAUFF standard coupling range.<\/p>\n\n\n\n

The coating offers maximum resistance to red rust\/base metal corrosion in practical application and exceeds even the highest requirements of corrosion protection class K5, which are defined in VDMA standards sheet 24576 for tube connections. The high ductility of the coating is the prerequisite for the above-average wear protection under high mechanical strain.<\/p>\n\n\n\n

In addition, the QRC-HI couplings now feature a manufacturer’s marking which allows quick identification and traceability.<\/p>\n\n\n\n

The compact size and the low weight of the QRC-HI (or QRC-HIB), the high level of quality and the universal suitability have remained unchanged: Both couplings are interchangeable with other brands where the design complies with ISO 14540.<\/p>\n\n\n\n
