Introduction As system pressures and other demands on today's equipment increase, so does the need for reliable hose and couplings. Why tolerate premature hose and coupling failures when we can help you avoid them with superior hose products and service? Caterpillar stands alone as the only equipment manufacturer who makes its own hose and coupling products. This catalog includes information on Caterpillar low, medium and high pressure hose and coupling product lines. We have a full stock of replacement products for earthmoving and other applications. That means no more running from one source to another to find the parts you need.
Caterpillar Hose Products Exceed Industry Standards Cat hose and couplings are designed to work together as a system for problem-free performance, no matter what brand of machine you operate. Testing performance for most products exceeds SAE requirements. Most hoses meet the MSHA flame resistance requirements as well. XT Hose and Couplings ... Differentiation Caterpillar's superior hose construction and testing differentiates it from other manufacturers. Caterpillar was the first to design and manufacture high pressure hydraulic hose known throughout the industry as XT hose. XT hose standards far exceed industry standards still today.
XT hose is impulse tested to one million cycles - twice the industry requirement - at 133% of working pressure using both new and aged hose. The differentiation does not stop at the hose. Caterpillar offers reusable couplings for XT hose to help keep your owning and operating costs at a minimum. Caterpillar reusable couplings for XT hose are the last coupling you should ever need. XT-3 ES Hose Caterpillar's XT-3 ES hose provides up to 20 times more abrasion resistance than the industry’s best rubber-covered hose, due to an exclusive cover formulated and manufactured by Caterpillar. Cat XT-3 ES hose works at half of the SAE bend radius without sacrificing cold flex capability.
Caterpillar ® 1956 Hose and Couplings Meet Your Mixed Fleet Needs (1956 hose (DIN 20023 4SP) and coupling) The product line joins the extensive line of high pressure XT hose components that have set the industry standard for reliability and durability for nearly 30 years. 2
