Multiquip 21158 Hose Assembly 1/2 ID x 24.0 Straight Ends

The Multiquip 21158 is a genuine OEM Hose Assembly 1/2 ID x 24.0 Straight Ends designed for HTX series hydrostatic ride-on power trowels, including the HTX44K5, HTX44Y4, HTX44Y5, HTX44K4, and HTXD6i. Sourced directly from Multiquip, this assembly matches the original equipment specification for a straight-in installation with no adapters or modifications needed at the connection points. Keeping the hydraulic or fluid circuit intact with a correctly sized hose is critical to consistent trowel performance and long-term system integrity.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional spec for this hose routing, ensuring correct inner diameter flow capacity and end-fitting compatibility.
• Straight-End Fittings on Both Ends — Straight ends on each side allow direct, aligned connections to the mating ports on the HTX series trowel, simplifying installation during service.
• Broad HTX Series Coverage — Confirmed fitment for HTX44K5, HTX44Y4, HTX44Y5, HTX44K4, and HTXD6i hydrostatic ride-on trowels.
• Maintains Full Fluid Flow — A correctly sized 1/2-inch ID hose sustains the intended flow rate through the circuit; an undersized or deteriorated hose restricts flow and causes sluggish or uneven blade response.
• Direct OEM Replacement — Part number 21158 cross-references directly to the original assembly, so you can confirm the correct part before ordering.

A hose assembly in a hydrostatic ride-on trowel carries hydraulic fluid between the pump, motor, and control components that govern blade pitch and machine drive. The inner diameter determines how much fluid can pass through at a given pressure, so a hose that is cracked, collapsed, or the wrong size will cause loss of hydraulic pressure and unpredictable blade or drive behavior. Replacing a worn hose with the correct OEM assembly restores proper flow and keeps the hydraulic circuit operating as the trowel was engineered to perform.
