JIC, UNF, UN adapters & Screw fittings

For many construction machines the JIC sealing system is used. It can be easily detected on the typical 74° sealing cone, which projects to the outside for a male thread and to the inside with the female thread. The male and also the female threads of the screw connection are parallel UN and UNF threads. We have listed here the most important adapters and screw connections made of galvanised steel and stainless steel.
