  "usage_notes": "This adapter allows mating of BSP parallel thread components with NPT threaded systems. The BSP side has a straight thread and relies on the provided washer to seal, while the NPT side seals via tapered threads. Handy for integrating imported (metric/BSP) parts into standard NPT pneumatic setups.",

  "warnings": [
    "Not rated for high-pressure hydraulic use without verification; intended for pneumatic pressures up to 500 PSI",
    "Periodic checks for leakage are recommended, especially if used near pressure limits",
