Question by: Jimmy R on Aug 17, 2025, 5:54 PM
what exactly is this fitting used for, the female spud with the copper part?
Answer by: Customer Support on Aug 19, 2025, 2:59 PM
Female spuds are used to create a threaded female connection point, typically where a hose or pipe needs to attach to a tank, vessel, or manifold. The copper component in this Kuriyama GJF-125 works alongside the spud to form a secure, sealed connection in industrial fluid handling setups. At 1-1/4 inch, it fits a fairly common port size you'd run into on a lot of standard hydraulic and industrial equipment.

Match-up is straightforward here. GJF-125 is the SKU and the supplier part number (MPN) for the Kuriyama Of America 1-1/4IN Female Spud w/ Copper S, so those identifiers point to the same item.
