FRAM PH4701 vs NAPA Gold 1190: Oil Filter Compatibility
Compare FRAM PH4701 and NAPA Gold 1190 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 M18x1.5 thread.
Quick verdict
Closest known dimensional difference: gasket OD -2.4 mm. Verify application-specific requirements before substituting.
- 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.
