#3 Tube Nut Stainless Steel 2pk

The #3 Tube Nut Stainless Steel 2pk from EARLS is an essential compression fitting component designed for secure, leak-free hydraulic and fuel line connections in high-performance applications. These tube nuts serve as the female threaded connector that pairs with AN-style tubing to create reliable, reusable hose assemblies. Whether you're building a custom hydraulic system, upgrading fuel lines on a motorsports vehicle, or maintaining industrial equipment, this 2-pack provides the precision fasteners needed for professional-grade results.

Manufactured from stainless steel, these #3 tube nuts offer superior corrosion resistance compared to standard steel alternatives, making them ideal for marine, outdoor, and aggressive chemical environments. Stainless steel construction ensures the nuts resist rust and oxidation over years of service while maintaining structural integrity under pressure cycling. The #3 size designation corresponds to standard AN tubing specifications, ensuring compatibility with industry-standard hose assemblies and fluid power systems. The two-pack format provides immediate backup inventory while minimizing reorder frequency and shipping costs.

Professionals in aerospace, automotive tubing, racing fuel systems, and industrial hydraulics rely on EARLS fittings for their proven durability and dimensional accuracy. Installation requires only a wrench—these nuts thread directly onto #3 AN tubing for a hand-tight seal with a single wrench turn, eliminating the need for specialized tools or excessive torque. Verify compatibility with your existing tubing size before ordering; #3 nuts are engineered exclusively for #3 tube diameter applications. Stock these stainless steel tube nuts in your toolbox, shop, or service kit for emergency repairs and planned maintenance.
