Fire hose couplings and adapters are configured to receive, by any of various types of interconnections, a wide range of attachments enhancing the utility of the associated fire hose. The attachments are secured to the coupler or adapter by way of an appropriate locking engagement, such as by a dovetail connector, setscrews, chemical attachment, adhesives and the like. The attachments cover a broad range of handles, reflective and directional devices, analog and digital sensors/monitors/indicators, and carabiners, and both threaded and unthreaded studs adapted for appropriate receipt of any of a broad range of attachments or uses.

The invention relates to a device for assisting the maneuvers of a hose, comprising a frame (2), having at least one cradle (20) which has an inner shape with a circular concavity (21) and displacement means (3), characterized in that the concavity (21) of the cradle extends along a circular of an angle beyond 180°.

A fire apparatus includes an engine, a fluid delivery system, and a controller. The fluid delivery system includes a first pump that provides a first fluid output at a first pressure, and a second pump positioned downstream of and coupled to the first pump in a serial arrangement. The second pump is driven by the engine. The second pump provides a second fluid output at a second pressure. During a first mode, the first fluid output is dischargeable from a low pressure discharge. During a second mode, the second fluid output is dischargeable from a first high pressure discharge and/or a second high pressure discharge, the engine operates at a first set point when the second fluid output is discharged from the first high pressure discharge, and the engine operates at a second set point when the second fluid output is discharged from the second high pressure discharge.

A flexible dry sprinkler has an inlet having an inlet orifice, an outlet, a flexible tube having a first end attached to the inlet and a second end attached to the outlet, an inlet seal for sealing the inlet orifice, whereby, when the inlet seal releases, fluid is permitted to flow from the inlet orifice to the outlet through the flexible tube, and a yoke positioned in the inlet, the yoke having a plurality of spaced-apart legs that permit the fluid to flow passed the yoke toward the outlet.

A modular fluid spray nozzle is constructed from an inner conduit, having a sidewall with a center hole, housed inside a center conduit that includes a window defined by a sidewall, and a flexible or rigid outer conduit wrapped around the center conduit and forming a chamber with the rectangular window. The chamber is in fluid communication with the center hole and with at least two apertures defined by the outer conduit. The inner conduit is configured to be coupled to any type of conduit material, such as PVC pipe or another modular fluid hose segment.
