Question by: Brent P on May 25, 2025, 10:25 AM
what's the thread setup on this plug, both ends? trying to figure out if it'll work with my existing lines before i order
Answer by: Customer Support on May 27, 2025, 6:46 AM
The male end runs a 15/16-inch UNEF thread, and the female end is 1/8-inch NPTF. Both thread types are common in hydraulic and fluid transfer setups, so if your existing lines match either of those specs, you should be in good shape for a direct connection.
