⚠ VERIFY BEFORE ORDERING
NPT ≠ BSPT — tapered threads look identical but are NOT interchangeable. Wrong thread = leak.
JIC (37°) ≠ AN (37°) ≠ SAE 45° — flare angles must match exactly.
Measure thread pitch with gauge — visual identification is unreliable
✓ BROKER TIP
Always use thread sealant (PTFE tape or pipe compound) on tapered threads (NPT/BSPT).
JIC/AN flare fittings seal metal-to-metal — never use tape on flare connections
