Question by: Jimmy S on Apr 5, 2026, 8:25 AM
What thread type and spec does this plug run? Trying to make sure it'll mate up right with a 1/8-27 port before I go ordering a handful of em.
Answer by: Customer Support on Apr 6, 2026, 1:58 PM
Male NPTF threads sized at 1/8-27, built to SAE J476 spec. That's a dry-seal thread standard, so it's engineered to seal on the threads themselves without relying on a separate sealant or tape in most installations. If your port is cut to 1/8-27 NPTF, this plug is a direct fit.

got a port that’s 1/8-27. is this the right plug for it?
Answer by: Customer Support on Aug 21, 2025, 6:58 AM
For a 1/8-27 port, this matches that thread size and it uses a male NPTF thread (SAE J476), so it’s intended to screw into a 1/8-27 NPTF female port.
