An example of typical banjo fitting components (left) with an identical fitting connecting a hose to a tee fitting. A general schematic, not to scale, showing the fluid path in an assembled banjo fitting. A pair of banjo bolts as used in automotive braking.
The flue system is composed of two flues, the inner flue and the outer flue. The outer flue draws air into the bottom of the sealed firebox to allow for combustion. The inner flue draws hot exhaust gasses from the top of the sealed firebox and vents them directly to the outside of the structure through either an adjacent wall or roof.
A conical hose-stream aimed around an opening—of a window or door, etc.—entrains smoke and thus increases the exhaust rate of smoke from the space. This is a process called hydraulic ventilation. This strategy might be used when the fire is small and protecting property from smoke damage can be achieved safely.

Forestry hose is a fabric-covered, flexible hose used to fight fires in grass, brush, and trees where a lightweight hose is needed to maneuver it over steep or rough terrain. Forestry hose comes in 1.0 and 1.5 in (25 and 38 mm) nominal inside diameters and is designed to operate at pressures up to about 450 psi (3,100 kPa).
A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect

A round galvanized steel duct connecting to a typical diffuser Fire-resistance rated mechanical shaft with HVAC sheet metal ducting and copper piping, as well as "HOW" (Head-Of-Wall) joint between top of concrete block wall and underside of concrete slab, firestopped with ceramic ...
A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control - for example, in the case of ...
