Replacement for Luber Finer LFH8705 Medium-Pressure Spin-On Filter

Yes. Dimensionally identical to the Luber Finer LFH8705 — same OD, length, flow direction, and double open-end configuration. Drops straight in with no modification required.

No. Under the Magnuson-Moss Warranty Act, manufacturers cannot void your warranty simply because you used an aftermarket part. SONA's elements meet or exceed performance criteria — your warranty is protected.

A nominal rating captures roughly 50–90% of particles at the stated size — and varies between manufacturers. An absolute rating means 99.5%+ capture efficiency, verified by ISO 16889 multi-pass testing of the media. This filter is 5 Micron.

Yes — independently verified. SONA's 5 Micron microglass media is tested to ISO 16889 with a Beta ratio of BX = 200, matching or exceeding performance in both efficiency and dirt-holding capacity.

Change the Luber Finer LFH8705 element when differential pressure reaches 25 PSID, or at your OEM service interval — typically every 500–2,000 operating hours depending on system load and contamination levels. Do not wait until the bypass valve activates.

Compatible with petroleum-based hydraulic oils, HH, HL, HM, or HV fluids, and most synthetic lubricants. The Viton seal provides broad chemical compatibility. Confirm with your fluid supplier for non-standard applications. It is not compatible with Skydrol.
