Product Description
The 58331-003 is a mechanical pressure relief indicator that provides visual confirmation when a relief device opens due to overpressure. This indicator serves aircraft fluid and gas circuits, commonly installed on fire-extinguishing containers to signal thermal relief discharge. The device operates passively—when system pressure exceeds relief valve settings, the indicator visibly confirms the discharge event.
Installation and testing must follow the Aircraft Maintenance Manual and approved maintenance data for your specific aircraft. Verify applicability in your aircraft's Illustrated Parts Catalog before installation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
