Question by: Duane B on Oct 18, 2025, 4:42 PM
got a 1/4 inch NPTF fitting on both ends of a manifold block i need to bridge, this hex nipple gonna thread right in on both sides?
Answer by: Customer Support on Oct 20, 2025, 6:43 AM
Both ends carry 1/4-18 male NPTF threads, so as long as your manifold ports are female NPTF at that same size, you're good on both sides. The threads meet SAE J476 spec, which is the dry-seal standard, so you get a pressure-tight connection without relying on tape or sealant to do all the work.

What kind of pressure can this hex nipple handle without failing?
Answer by: Customer Support on Dec 23, 2025, 6:16 AM
It's rated for a maximum dynamic pressure of 6,000 psi, so it should hold up well in high-pressure systems.

Answer by: Customer Support on Nov 18, 2025, 6:29 AM
Both ends are male NPTF threads, 1/4-18, and they follow the SAE J476 thread specification.
