In this article, based on the obtained formula for calculating the strength of a pressure fire hose(PFN) under the action of internal hydraulic pressure, the dependence of the disruptive pressure in alatex pressure fire hose, designed for an operating pressure of 1.6 H, on such parameters as geometric densities on the warp and the weft, is studied.As a result of the studies, the pattern of decreasing the disruptive pressure of a fire hose with an increase in the geometric densities on the warp and the weft of a reinforcing frame of a pressure fire hose was experimentally established. When designing new fire hoses, it is important to take into account the significant dependence of the disruptive pressure on the geometric densities on the warp and the weft of a reinforcing frame. Recommendations are given on choosing the optimal parameters for a woven reinforcing frame of latex pressure fire hoses with a diameter of 77 mm.
