Question by: Glen M on May 7, 2025, 9:00 AM
What thread spec does this plug run on, and is it NPTF or just NPT?
Answer by: Customer Support on May 9, 2025, 6:54 AM
Male NPTF, 1/8-27, built to SAE J476. NPTF threads are designed to seal on the threads themselves rather than relying on a separate sealant or gasket, so you get a more reliable pressure seal than standard NPT in most hydraulic and pneumatic setups.
