1639320 Hose A Fits Caterpillar Models

One New Aftermarket Replacement High Pressure Hose Assembly for Caterpillar (Cat) Equipment

This aftermarket replacement hose assembly (Cat part number 1639320 / 163-9320) is an XT-3 ES type high pressure hydraulic hose designed to transfer petroleum-based hydraulic fluid at high pressures between pumps, motors, and machine components in Caterpillar heavy construction equipment. The XT-3 ES (Enhanced Spiral) design uses a fabric-reinforced synthetic rubber inner tube with four to six plies of spirally-wrapped high-tensile steel wire reinforcement, separated by layers of synthetic rubber, with an oil-, weather-, and abrasion-resistant outer cover. This hose type is rated for high-pressure hydraulic service applications and is engineered to operate at half the SAE standard bend radius, allowing flexible routing in confined spaces.
