hoseguard air fuses pluged in



Protect your most important assets: Your employees, machinery and equipment!


The HoseGuard® offers simple and efficient protection to pneumatic systems in the event of a broken compressed air hose or pipe. The air supply is immediately shut off by the HoseGuard® should the volume of air exceed a set value. This "value" is factory set to allow normal air consumption when using air tools. Should the air consumption exceed the set value (that would happen when a compressed air line is severed), an internal piston instantly shuts off the main flow. An integral bleed hole allows some air to flow through. This enables the line pressure to automatically reset the HoseGuard® once the main break is repaired.

On request - also available in Stainless Steel
