Stat-O-Seals 3/8in -3AN 2pk

The Stat-O-Seals 3/8in -3AN 2pk by EARLS are precision sealing washers designed for high-pressure hydraulic and fluid transfer applications in automotive, aerospace, and industrial systems. These washers solve the critical challenge of preventing fluid leaks at AN (Army-Navy) fitting connections where standard seals fall short. Engineered for professionals and serious enthusiasts who demand reliability under extreme pressure, this two-pack provides the redundancy and convenience needed for system repairs, maintenance, or new installations.

Each Stat-O-Seal combines a 0.375-inch ID aluminum washer with an integrated rubber O-ring, creating a dual-seal mechanism that delivers superior leak prevention compared to single-element designs. The aluminum washer provides structural integrity and uniform pressure distribution, while the elastomer O-ring conforms to microscopic surface irregularities for an airtight seal. The -3AN thread specification corresponds to 3/8-inch port fittings, making these washers compatible with standard AN hydraulic lines used in racing fuel systems, brake circuits, and transmission cooler installations. This compact design—measuring just 1.3 x 0.3 x 3 inches and weighing a mere 0.01 lbs—fits easily into tool kits and maintains minimal system footprint.

Professionals restoring vintage race cars, building custom hydraulic systems, or performing OEM maintenance will appreciate the quality assurance backing EARLS components. The two-pack format accommodates both primary installation and spare inventory for emergency field repairs, eliminating downtime caused by leaking connections. Whether you're sealing fuel delivery systems, brake lines, or power steering circuits, these washers install quickly onto -3AN fittings and provide dependable performance across temperature extremes and vibration-intensive environments. Keep a set on hand whenever AN hydraulic integrity matters.
