NAPA Gold 7100 vs FRAM PH2: Oil Filter Compatibility

Compare NAPA Gold 7100 and FRAM PH2 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.

Quick verdict

COMPATIBLEScore: 89

Strong dimensional fit. 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.

What matters most in this comparison?

Thread match: A direct spin-on substitute starts with the same thread size. If the threads differ, the comparison stops there.

Gasket fit: Even when thread size matches, the gasket outside diameter and inside diameter still control whether the filter seals safely against the mounting surface.

Height difference: Small height differences may be acceptable, but longer filters can create clearance problems in tighter installations.

Valve behavior: Bypass and anti-drainback differences can matter in real-world service, especially on cold start or in applications sensitive to oil drain-back.
