What size thread is a ph3506 oil filter?
The PH3506 oil filter uses a 3/4-16 UNF thread. This is the standard mounting size for many spin-on filters used in American-made engines.
In this article, we explain the exact thread specification for the PH3506, how to verify compatibility with your engine, and practical tips for replacing and installing the filter. The goal is to help you confirm the right fit and avoid common installation mistakes.
Thread size specification
The PH3506 is designed to mount with a 3/4-16 UNF thread. This means a 0.75-inch diameter thread with 16 threads per inch, the common automotive standard for many spin-on oil filters.
Why this size matters
Using the correct thread size ensures a proper seal and prevents leaks or cross-threading. An incorrect thread can prevent the filter from threading on correctly or damage the mounting point. Always verify the thread size against your vehicle’s specifications and the filter’s packaging or catalog entry.
Verification and compatibility
To confirm compatibility, consult your vehicle’s owner manual, the Purolator catalog entry for PH3506, or the retailer’s product page. If replacing an existing filter, compare the old filter’s thread size and gasket to the PH3506’s specifications.
Checklist to confirm fitment before purchasing or installing:
Check packaging or product listings for the exact thread specification: 3/4-16 UNF.
Measure the old filter’s threads with calipers or a thread gauge to confirm a 0.75-inch diameter and 16 threads per inch.
Cross-check with your vehicle’s model year and engine family in official catalogs or via a dealer.
Conclusion: The PH3506’s standard mounting thread is 3/4-16 UNF. If your engine requires a different thread size, do not force the fit—seek guidance from the manufacturer or a qualified technician.
Practical installation tips
When installing a new PH3506, lightly lubricate the gasket with clean engine oil, hand-tighten until snug, and then follow the manufacturer’s instructions for any final tightening. Avoid over-tightening, and verify the seal and connection after the engine runs and the oil pressure stabilizes to ensure there are no leaks.
Summary
The PH3506 oil filter uses a 3/4-16 UNF thread, a common size for many spin-on filters. Always verify with the vehicle’s manual or the filter packaging to ensure compatibility, and consult a professional if there is any doubt about fitment.
