Mann Tek 3″ Stainless Steel Industrial Break-away Coupling Male NPT

Original price was: $4,980.35.Current price is: $3,035.68.

Coupling is designed to minimize spillage and damage associated with drive away and pull away incidents.
Typical applications: loading rack

Designed to be installed between a fixed point (pipe, pump, manifold) and a hose
Coupling automatically senses an excessive load, closes the valves and disconnects
High flow rate / low pressure drop

Also available in 150# Flange, BSP thread, DN Flange, 300# ASA Flange, Grooved Ends or any combination thereof. Consult Dixon for more information.
Optional Non-closure Design available, consult Dixon for more information. The non-closure design is an economical alternative which allows the coupling to break away due to pull-away/drive-away incidents thus protecting piping systems and equipment. The design allows spillage of product in these instances due to the lack of valving in the coupling. Useful applications where non-hazardous product is being conveyed and where there are no environmental concerns.

The safety break-away valve consists of two halves, each with a valve that has an O-ring seal. When the safety break-away couplings separate, it allows the valves to close. The two valves close rapidly, minimizing exposure to personnel and the environment.
Safety break-away couplings have three external break bolts. In the case of axial tension all of the bolts take up the force corresponding to the break force on the hose with a safety margin. Non-axial forces concentrate the tension forces more strongly on one bolt, so that the safety break-away coupling reacts in a natural way to the reduction of the hose break forces.
