The Multiquip 57479 Hydraulic Fitting RW-3015 P54/KA/KA4B is a genuine OEM component designed for the KA4B and RW-3015 RAMMAX ride-on roller series. Sourced directly from Multiquip, this fitting is built to the exact specifications of the original hydraulic system, ensuring a leak-free connection and consistent hydraulic pressure throughout the roller's drive and vibration circuits. Confirmed fitment covers KA4B and RW-3015 models, making this the correct choice when servicing or rebuilding the hydraulic plumbing on these machines.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to original thread form, port geometry, and sealing surface tolerances so hydraulic pressure is maintained without weep or bypass.
- Direct-Connect Replacement — Matches the original fitting configuration on KA4B and RW-3015 hydraulic lines, seating correctly without re-threading or adapter workarounds.
- Confirmed Roller Fitment — Verified for KA4B and RW-3015 RAMMAX ride-on rollers in the Multiquip P54 series family.
- Sustained System Pressure — A sound hydraulic fitting keeps drum drive and vibration response consistent; a failing or mismatched fitting causes pressure drop, sluggish drum control, and potential hydraulic fluid loss.
- Fuel and Fluid Safety Compliance — Hydraulic fittings are a pressure-bearing connection point; using the correct OEM fitting prevents unexpected line failure under operating load.
A hydraulic fitting is a threaded or push-to-connect junction that joins sections of hydraulic hose or tubing within the roller's closed hydraulic circuit. On ride-on rollers like the KA4B and RW-3015, the hydraulic system powers both the drum drive and the vibration mechanism, so every fitting in the circuit must hold rated pressure without seeping. When a fitting corrodes, strips, or cracks, hydraulic fluid escapes, pressure drops, and the roller loses drive force or vibration output — stalling compaction work entirely until the fitting is replaced.
