Hydraulic Fitting and Thread Identification: JIC vs. ORFS vs. NPT vs. BSPP
Identify hydraulic fittings and threads fast: tell JIC, ORFS, NPT, and BSPP apart by pitch, seat angle, and sealing method, with a quick-reference table.
JIC vs ORFS
JIC, ORFS, NPT, BSPP: A Field Guide to Hydraulic Fitting Threads
Identify hydraulic fittings by thread, seat, and dash size. JIC 37-degree flare, ORFS face seal, NPT taper, BSPP parallel, ORB, Code 61/62, DIN 2353 — what each looks like and how to tell them apart.
