400-0086

When monitoring extremely high pressures—such as in aerospace landing gear, hydraulic systems or heavy‑duty industrial applications—precision and durability make all the difference. The 400‑0086 gauge (also referenced by NSN 6685‑01‑032‑7978) is designed to meet those exacting standards. asap-components.com+1 With a Bourdon‑tube actuation system and AISI 302 steel sensing element, the unit delivers reliable performance even in challenging environments. The large 4.5″ dial and clear graduations (increments of 50 psi) provide immediate visibility—critical when reading pressure under load. Accuracy to ±1% full‑scale means tighter control, fewer safety margins and more efficient system tuning. Compared to generic gauges that may lack aerospace‑grade certification, this gauge is manufactured for use in mission‑critical gear and recognized under the aerospace NSN registry. WBParts Whether you’re outfitting a maintenance shop for aircraft hydraulic servicing, installing instrumentation on industrial equipment, or replacing legacy components in a high‑pressure loop, the 400‑0086 stands out for its certified accuracy, rugged build and long‑term reliability. Engineers and maintenance teams will appreciate its fit‑and‑forget quality, reducing downtime and re‑work.
