"Medium-pressure hoses" typically feature one and two-wire braided construction. These hoses are frequently found on construction equipment, heavy-duty trucks and fleet vehicle applications. In general, braided hose is selected for its flexibility.
At one time in the industry, two-wire braided hoses was not commonly used in many applications. But the advent of larger, off-road specialty equipment drove the creation of spiral hose, which is very well suited for applications where extremely high impulse pressure is encountered.
Today hydrostatic drives using four and six-wire spiral hoses can be found on everything from lawn tractors to earth movers. Because today's world demands faster, more powerful equipment requiring increased working pressures.
