When I went through the Navy's 5 day firefighting school half a century ago, they used 1-1/2 inch NPSH everywhere except on aircraft carrier flight decks and hanger decks. 2-1/2 inch was used on aircraft fires. Below decks, in passage ways and compartments, 1-1/2 inch is more flexible and NPSH rocker lug couplings are easier to pull over water tight door thresholds than NH. An additional benefit is the finer thread on the NPSH can be made secure with wrist effort without using a lug wrench. Further more, NAVY nozzles for use below decks are 95 GPM because that is all the nozzle reaction one sailor should be handling. Multi-man hose teams are a luxury aboard ship in confined spaces. The team is usually one nozzle man and one hose tender who may not be right behind the nozzle man. Yes, double jacket is more durable and required for municipal fire departments. However forestry hose is single jacket, it doesn't get dragged across curbs, the corners of masonry walls or angle iron edges. It is lighter weight, easier to haul around and more flexible, Not everyone needs a hose that can fight 500 fires before retirement.

Thx you but what type of hose would you buy for a home in Colorado use only . Small community in forest area gravel roads with a number of fire hydrants ? ? Thx

we use Storz couplings. so we don't have the problems with the male and female side.

Hi, Storz couplings are widely used by fire departments, and, as mentioned, do not have a female or male side. For more information on Storz, please watch our video: kzread.info/dash/bejne/rHmFl9CNiabPfLQ.html Thanks - FireHoseDirect
