NPT and SAE-ORB Diagnostic
Pressure Gauge Adapters
Parker’s NPT and SAE-ORB direct-connect pressure gauge
adapters are available in the most common North American
tube/hose connections — ORFS and 37° Flare (JIC). North
American pressure gauge manufacturers offer gauges primar-
ily with NPT and some with SAE-ORB port stud options. These
37
° flare and ORFS connectors are designed to attach pressure
gauges to hose swivel ends or directly to run / branch tees for
in-line diagnostic applications as shown on the right.
