3/8 NPT Hydraulic Quick Couplers and Hose Fittings

A 3/8 NPT fitting is a National Pipe Thread tapered connector with a 3/8-inch nominal diameter, commonly used in hydraulic systems for reliable, leak-resistant connections.

ORB fittings use an O-ring for sealing with straight threads, while NPT fittings seal through tapered thread interference. ORB provides easier installation and reusability.

Yes, using proper adapters like our JIC to NPT converters allows safe connection between different thread standards while maintaining system integrity and pressure ratings.
