trying to hook two 1/2 inch npt lines together, is this the right coupling or am i missing something

For a straight coupling between two matching pipe threads, it fits the bill since it has 1/2-14 female NPTF threads on both ends. It is meant to join two 1/2-14 male NPT connections.

Got a grease system on an old compressor setup and need a half-inch female NPT on both ends. this the right fit?
Answer by: Customer Support on Oct 17, 2025, 6:05 AM
Female NPTF threads on both ends, both sized at 1/2-14, so yes, that matches what you're describing. The brass construction holds up well in grease applications, and the product is specifically rated for that use. Just confirm your existing fittings are also NPTF-compatible and you should be in good shape.
