Hi-Force high-pressure couplings and connectors are designed for simple system connections and the installation of your Hi-Force hydraulic systems. All Hi-Force couplings and connectors are designed for a maximum operating pressure of 700 bar. Hi-Force recommends the use of dust caps with quick-release couplings to protect the coupling thread while protecting the hydraulic system against contamination. Always specify Hi-Force couplings and adapters for use with your Hi-Force hydraulic tools.
