Fleetguard LF781 vs LUBER-FINER PH2835: Oil Filter Compatibility
Compare Fleetguard LF781 and LUBER-FINER PH2835 oil filters by compatibility, dimensions, thread size, gasket fit, bypass valve, anti-drainback valve status, and match confidence. Use this comparison as a fitment review, not as an automatic substitution guarantee. Both use a 3/4-16 thread.
Quick verdict
Candidate adds internal bypass; usually redundant with engine-mounted bypass
- Thread size is the first hard-fit check for any comparison of spin-on filters.
- Gasket OD and gasket ID are the most important seal-related dimensions.
- Height differences can matter for clearance even when thread and gasket fit appear close.
- Bypass and anti-drainback differences may be important, depending on the application.
