Hose & Couplings

Caterpillar is an industry leader in designing and manufacturing our own Hoses and Couplings.

High quality hose products mean fewer hose changes. Cat offers a broad line of high, medium and low-pressure hoses and couplings that are engineered and tested far beyond industry standards for top performance and long life.

Cat ToughGuard™ Hoses, for example, feature a polyethylene cover that has surpassed 2 million cycles of abrasion testing without failure!

Permanent and Reusable coupling options are offered for a wide variety of hose types.

Cat® hydraulic hoses with embedded lay line information

Cat Hose has embedded lay line information and is designed to achieve half of the SAE bend radius.

Foam projectiles used to clean Cat® hose assemblies

Certified Crimp and Certified Clean stickers are added to confirm that hose assembly is crimped to specifications and has been cleaned properly with foam projectiles.

Assorted Cat® hose couplings and fittings

Cat Hose and Couplings are tested as a system and above industry requirements to ensure that the coupling and the hose are a perfect fit.

Cat® hose assembly fitted with its part number tag

The Hose Assembly Part Number is provided on a tag to allow for quicker ordering and assembly turnaround time. Provide this part number to your Caterpillar Dealer when you are ready to replace your hose assembly.
