Product Questions & Answers

got a port that calls for 1-1/2-11-1/2 NPTF. is this the right plug for that thread?

Question by: Tony E on Sep 24, 2025, 9:39 AM

For thread fit, it matches a male NPTF thread in size 1-1/2-11-1/2, built to the SAE J476 thread specification.

Thread size on this one is 1-1/2-11-1/2 NPTF, does that match up with SAE J476 fittings?

Question by: Steve W on Jul 30, 2025, 10:05 AM

Yes, and it's worth knowing why that matters. NPTF threads are engineered to create a pressure-tight seal through thread interference alone, and the SAE J476 spec is exactly what governs that fit. So if your system is built around J476-compliant ports or fittings, this plug should thread right in without needing additional sealant to hold pressure. The 1-1/2-11-1/2 sizing refers to 1.5-inch nominal diameter at 11.5 threads per inch, which is the standard for that pipe size under NPTF.
