Serves fire departments across the US. Re-coupling fire hose consists of extracting the old copper rings, tail gaskets, measuring bowl size for accuracy and re-coupling it with new brass rings and tail gaskets. If you have old couplings, they can be salvaged and used on new & used hose. All fire hose that is new or re-coupled is service tested to NFPA 1962 2018 standards and is stamped with our O's Custom Hose Logo, with the exception of 4" & 5" LDH. Build your custom fire hose how you need it, choose your size, choose any length, hose type, color, coupling material, double female & male couplings and your thread. Stenciling fire hose is also available.
