Frequently asked questions

Have a question? Refer to our FAQs for answers to your most common questions!

Low and medium pressure hose is a commodity product. The Cat brand does not add any value.

Caterpillar uses superior materials and exacting manufacturing processes. It subjects its Low & Medium hose to extensive endurance testing. Cat Low & Medium pressure hose surpasses performance expectations under extensive and above average working conditions.

Cat hose is the same as the competition?

Caterpillar has been designing and manufacturing hose products since the 1960s. Cat XT high pressure hose and couplings provide higher abrasion resistance, offer half the bend radius, and the robust multiple-ply construction allow it to exceed industry standards for superior hose performance and reliability. Cat couplings are engineered, manufactured and tested with Cat hose as a system to provide maximum performance in a wide range of applications.

Hose failures often come at unexpected times – what should I expect in terms of replacement time to get a hose?

If you know the hose assembly part number, there is no competitor that is as convenient as a Cat dealer. The Cat dealer is the only one a customer can call who can build a hose assembly from the assembly part number. The dealer is just a telephone call away and can build most hose assemblies in 30 minutes or less.
