SGR coupling plugs
These threaded couplings are ideal for heavy-duty applications such as hammers, attachments, stone crushers, etc.
Thanks to reinforced internal components, the MQS SGR couplings are highly resistant to backflow, flow pulses, pressure pulses, vibrations and hose bending (forces acting on the coupling via the hose)
Connection and disconnection is achieved by screwing the coupling together, and is also possible under nominal pressure
The hexagonal profile of the outer sleeve ensures easy connection and disconnection under high pressure
• High pressure version
• Heavy Duty version
• The connection is secured by the thread between plug and sleeve
• Shut-off via seat valve
• Interchangeable with similar products available on the market
