KURIYAMA 2 INCH FEMALE PIN LUG HOSE SHANK COUPLING

It's a 2-inch female pin lug hose shank coupling.

Pin lug couplings use protruding lugs on the body that engage with a mating wrench or spanner for tightening and connection, rather than a standard hex or threaded end you'd turn by hand or with a pipe wrench. The female end here connects to a mating male fitting, while the hose shank side barbs into your hose. It's a common configuration on industrial hose assemblies where quick, secure engagement matters and where a standard threaded union just isn't practical.

Function-wise, ABF200 is a female pin lug coupling with a hose shank end, in a 2 inch size. That means one side is the female pin lug connection, and the other side is the shank meant to go into a hose.

Pin lug couplings have small lugs on the outside of the collar that let you use a spanner wrench to tighten or loosen the connection. A standard hose shank coupling typically relies on clamps or threaded connections alone. The pin lug design gives you a more positive grip point during assembly, which makes it easier to get a solid, secure fit on the hose end without the connection walking on you during tightening.

This coupling is designed for a 2-inch hose, ensuring a snug and secure fit for your connections.
