JIC, UNF, UN adapters & screw connections

The JIC sealing system is used in many construction machines. It can be easily recognized by the typical 74° sealing cone, which projects outwards on an external thread and inwards on an internal thread. The external and internal threads of the screw connection are parallel UN and UNF threads. We have listed the most important adapters and screw connections made of galvanized steel and stainless steel here.
