Tuff-Flex Series abrasion resistant hydraulic hose maintains all of the specifications and construction qualities of the Pressure-Flex Series, but with the added Tuff-Flex rubber cover for superior abrasion resistance. Made of special compounds, the Tuff-Flex cover offers 25 times the abrasion resistance of standard cover hydraulic hose, increasing service life, lowering maintenance, and eliminating the need for costly hose protectors like spring guards and nylon sleeves. For added value, choose Tuff-Flex abrasion resistant hydraulic hose. For the ultimate in a tough and rugged hydraulic hose cover, ask about our “Armor-Clad” hose series. For specifications and other information on Unisource couplings, check out the Hydraulic Fittings section of our website. We also offer accessories such as sleeving, adapters, and flange kits. For permanent attachment of fittings to hose, see our extensive line of Crimping Equipment.
