Hose Jacket

What Is Hose Jacket?

A hose jacket (such as the Cooper hose jacket) is a hinged metal metal cylinder lined with rubber gaskets that can be clamped around a bursting or leaking section of pressurized fire hose (1½-inch to 3-inch) to seal leaks without interrupting water flow.

Why Hose Jacket Matters on the Fireground

A burst hose line inside a burning building cuts off water supply to the nozzle team immediately while flooding the structure. Clamping a hose jacket over the rupture instantly seals the leak, keeping the line charged and operational without shutting down the pump.

Relevant NFPA Standards

• NFPA 1930: Standard on Fire and Emergency Service Use of Thermal Imagers, Two-Way Portable RF Voice Communication Devices, Ground Ladders, Rescue Tools, Fire Hose, and Fire Hose Appliances

Field Procedures & Tactical Steps

1. Locate the rupture or pinhole leak on the pressurized hose line.
2. Open the hinged hose jacket and center it directly over the leaking section of hose.
3. Squeeze the two halves of the jacket firmly around the hose until the locking latch clicks securely.
4. Verify that the internal rubber gaskets have completely sealed the leak.
5. Replace the damaged hose section with a fresh line as soon as incident conditions permit.

Common Context & Application

Carried on engine companies to quickly repair line ruptures during active fire suppression or supply line operations.
