Steel UN, UNF & JIC Threaded Nipples and Adapters – External Thread
Steel UN, UNF and JIC threaded nipples and adapters with external threads are designed for hydraulic systems, high-pressure installations and industrial machinery. They provide a strong, reliable and leak-tight connection where precise threaded fittings are required.
At the POLBERIS online store you will find steel UN, UNF and JIC threaded nipples and adapters manufactured from high-quality carbon steel for excellent durability and dependable performance in demanding working environments.
These products are also commonly known as JIC adapters, UNF adapters, UN thread fittings, hydraulic adapters, male adapters, threaded connectors, pipe nipples, threaded extensions, reducing adapters and hydraulic thread fittings.
UN, UNF and JIC thread fittings are widely used by hydraulic engineers, welders, mechanics, maintenance technicians, machine builders and industrial installers for connecting hydraulic hoses, pumps, valves, cylinders, manifolds and other hydraulic components. JIC connections with a 37° flare are especially popular in mobile hydraulics, agricultural machinery, construction equipment and industrial hydraulic systems.
Whether you need a standard JIC fitting or a professional UN/UNF threaded adapter, POLBERIS offers a wide selection of reliable steel threaded fittings for hydraulic and industrial applications.
