Multiquip 21772 Hose Assembly 3/8 ID x 17.00 Straight Ends

The Multiquip 21772 is a genuine OEM Hose Assembly 3/8 ID x 17.00 Straight Ends designed for Whiteman hydrostatic ride-on power trowels including the STX55J6, HTX44Y4, HTX44Y5, and STX55Y6. As a direct Multiquip OEM part, 21772 is manufactured to the same specifications as the original component installed at the factory, ensuring a correct, trouble-free installation without guesswork. DHS Equipment sources this part directly through authorized Multiquip channels, so you can be confident you are receiving an authentic replacement. If your trowel is showing signs of hydraulic hose wear, cracking, or leaking, replacing with part 21772 restores the hydraulic circuit to proper operating condition.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original pressure rating and inner diameter specification for this hose circuit, eliminating the risk of undersized or incompatible fittings.
• Straight-End Fitting Configuration — The straight-end terminations on both sides allow direct installation into the existing hydraulic ports without adapters or re-routing.
• Confirmed Fitment — Verified for STX55J6, HTX44Y4, HTX44Y5, and STX55Y6 Whiteman hydrostatic ride-on power trowels.
• Hydraulic Circuit Integrity — A correctly functioning hose maintains consistent hydraulic pressure to the blade pitch or drive circuit; a cracked or leaking hose causes loss of blade control and uneven finishing.
• Direct Multiquip OEM Sourcing — Sold by DHS Equipment through authorized distribution, ensuring part authenticity and correct part number traceability.

A hydraulic hose assembly like the Multiquip 21772 carries pressurized hydraulic fluid between components in the trowel's hydrostatic system, which controls blade pitch adjustment and machine drive. The 3/8-inch inner diameter and fixed 17.00-inch length are matched to the specific routing and flow requirements of this hose position on the STX and HTX series machines. When a hose develops a crack, pinhole leak, or fitting failure, hydraulic pressure drops and the operator loses precise control over blade angle, directly affecting the quality and consistency of the concrete finish.
