AN-16 Poly Washer

The AN-16 Poly Washer is a precision sealing component designed for hydraulic, pneumatic, and fluid power systems where reliable, leak-free connections are critical. This AN-16 poly washer serves as a compression seal at connection points, preventing fluid migration and maintaining system integrity under pressure. Operators and technicians in aerospace, automotive, and tactical applications depend on AN-spec washers to meet exacting performance standards and regulatory compliance requirements.

Manufactured from PTFE (polytetrafluoroethylene), the AN-16 Poly Washer offers superior chemical resistance and low friction properties essential for demanding applications. With an outer diameter of 1.688 inches, an inner diameter of 1.313 inches, and a thickness of 0.125 inches, this washer delivers consistent compression and seal performance across temperature extremes. PTFE material resists degradation from oils, fuels, coolants, and solvents, ensuring the washer maintains its sealing properties throughout its service life without hardening or cracking.

Technicians performing equipment maintenance, repairs, or assembly will find the AN-16 Poly Washer essential for restoring factory-spec connections on hydraulic lines, pump fittings, and manifold blocks. Each washer meets AN (Army-Navy) standards, ensuring compatibility with standard AN fittings and connectors. The compact 0.01 lb weight and compact dimensions make it ideal for kit building, field repairs, and OEM replacement applications where space and weight margins are tight.
