TB 62 2-INCH HIGH-RISE HOSE SYSTEMS Flashcards
TB 62 2-INCH HIGH-RISE HOSE
This hose is of a single jacket construction utilizing nitrile rubber impregnated synthetic yarn as the cord material. It comes in 50 foot lengths with 1-1/2” couplings and is ribbed to reduce wear and increase grip. The shoulder of the couplings are tapered to reduce snagging

This system utilizes a Pressure Reducing Valve (PRV) when the pressure at the outlet exceeds 150 psi. Therefore, it is possible in new construction to encounter orifice plates on the upper floors where the system pressure falls below 150 psi. This will typically be the top six to eight floors.
