The Parker 12CS and 50CS Series Coreless Medium Pressure Filters are designed as a practical alternative to traditional spin-on can filters in pressure line hydraulic applications. Rated for a maximum allowable operating pressure of 500 psi (34.5 bar), these filters are commonly used in mobile and industrial equipment including agricultural machinery, construction equipment, hydrostatic drives, industrial power units, and machine tools.

Each assembly features a reusable aluminum bowl and a patented coreless Ecoglass element constructed with reinforced polymer end caps, microglass media, and polymer pleat support. The permanent core is integrated into the bowl, and the design includes a zero-leakage bypass valve and head-to-bowl sealing configuration. Standard element collapse rating is 150 psid (10.3 bar), with fatigue rating to 400 psi and a 2.5:1 design safety factor.

The 12CS Series supports nominal flows up to 20 GPM and the 50CS Series up to 40 GPM. Ecoglass media options are available in 2, 5, 10, and 20 micron ratings with Nitrile or Fluorocarbon seals. Visual, electrical, and analog differential pressure indicators are available, along with multiple SAE, NPT, BSPP, and manifold mount configurations.
