Truck Mixer Products Filter Element V3.0520-08 RB31303

This hydraulic filter element carries dual part codes V3.0520-08 and cross-reference RB31303, engineered exclusively for heavy-duty concrete mixer truck hydraulic circuits. It fits standard pressure filter housings on mixing drum drive systems, serving as a direct drop-in replacement matching original dimensional tolerances without housing modification. All machining follows industrial hydraulic filter ISO testing standards to meet construction site continuous operation demands.

Media is a pleated synthetic blend, rated for 10-micron absolute. Handles hydraulic oil, transmission fluid, and lube circuits common on mixer drums and PTO systems. Bypass valve setting matches OEM at 25 PSI.

Steel end caps and center tube are welded, not glued. Nitrile seals come pre-lubed. Burst pressure tested to 290 PSI. This one holds up to heat, shock loads, and the constant vibration from drum rotation.

Change interval depends on your oil analysis and duty cycle, but typical mixer applications see 500–750 hours. If you’re running in dusty jobsites, check it sooner—the pleat pack loads fast with silicate dust.

Packaged individually in a sealed bag with gaskets included. OEM part number cross-referenced on the box. Stock code RB31303 supersedes earlier revisions. Fits all TMP filter heads with the 3.0520 base thread.
