Question by: Kurt F on Mar 22, 2026, 11:10 AM
Does this plug meet any kind of thread standard, or is it just a generic fit?
Answer by: Customer Support on Mar 24, 2026, 6:53 AM
SAE J476 is the spec it's built to, which covers the 1/4-18 Male NPTF thread on this plug. NPTF threading is a dry-seal design, meaning the threads themselves form the seal under pressure rather than relying solely on tape or sealant. That standard matters when you need a consistent, reliable fit across industrial fittings and ports.

It matches a 1/4-18 male NPTF thread, built to the SAE J476 thread specification, so it is the correct size and type for a 1/4-18 NPTF female port.
