Hydraulic Fitting Comparisons

Side-by-side comparisons of the most commonly confused hydraulic fitting standards. Each comparison covers thread differences, seal types, pressure ratings, and when to use each.

JIC vs NPT

JIC fittings use a 37-degree flare with straight threads and a metal-to-metal seal.

BSP vs NPT

BSP (British Standard Pipe) and NPT (National Pipe Thread) are the two dominant pipe thread standards worldwide.

ORFS vs JIC

Both are high-pressure hydraulic fitting standards.

DIN vs BSP Hydraulic Fittings: Metric vs British Thread Systems

DIN fittings use metric threads per ISO 8434 with a 24-degree cone seal.

ORFS vs NPT Hydraulic Fittings: O-Ring Face Seal vs Tapered Pipe

ORFS uses a flat-face O-ring seal with straight threads.

JIC vs DIN Hydraulic Fittings: 37-Degree Flare vs Metric Compression

JIC uses SAE 37-degree flare cone seal with UNF threads (North American standard).

SAE ORB vs ORFS Hydraulic Fittings: Two O-Ring Seal Standards

Both ORB and ORFS use O-rings for leak-free sealing, making them superior to NPT for hydraulic applications.
