Podavelle AN3 Male-to-Male Adapter Couplers 2PCS — 304 Stainless Steel, CNC-Machined Leak-Resistant

Podavelle AN3 (3/8-24 UNF) male-to-male stainless steel adapter couplers are precision CNC-machined fittings designed to join AN3 fluid lines securely in brake, clutch, fuel, oil and coolant systems.

This two-piece pack of AN3 male-to-male adapters is built from 304 stainless steel for corrosion resistance and long service life. Each coupler uses standard 3AN (3/8-24 UNF) threads, making it compatible with common aftermarket hoses and hard lines. Podavelle machines these fittings to tight tolerances to help ensure leak-free connections when installed correctly. Note: professional installation is strongly recommended; installation instructions are not included.

How do these AN3 male couplers fit into vehicle fluid systems?

These adapters act as straight connectors between two AN3 female-threaded components or hose ends, restoring continuity in fluid circuits without altering hose routing. They are commonly used where a short, robust connection is required and where re-flaring or custom fabrication would be impractical.

• Thread size: AN3 (3/8-24 UNF) male to AN3 (3/8-24 UNF) male
• Material: 304 stainless steel for corrosion resistance
• Typical uses: brake, clutch, fuel, oil, coolant, gauge and power steering lines
• Sold as a pack of two identical adapter couplers

Which fluids and systems are these fittings compatible with?

The adapters are suitable for a wide range of automotive and industrial fluids provided the rest of the system materials are compatible. They work well with common fuels, lubricants and coolants used in performance and street vehicles.

• Compatible fluids: gasoline (unleaded), fuel blends, oil, brake fluid and methanol
• Also suitable for water-based coolant and oil pressure or gauge lines
• Not a hose — use with proper AN3 hose ends or female AN3 ports

What benefits come from CNC-machined 304 stainless steel construction?

CNC machining delivers consistent thread profiles and tight dimensional control, reducing risk of cross-threading and improving sealing reliability. 304 stainless steel offers good strength and corrosion resistance in automotive environments, making these adapters durable under typical service conditions.

• Precision machining for accurate thread engagement and fit
• 304 stainless resists rust and ordinary road chemicals
• Durable under vibration and heat found in engine bays

Any installation tips or limitations I should know before buying?

These couplers are straightforward components but must be installed with compatible AN3 fittings and tightened to correct torque. Professional installation is advised to ensure a safe, leak-free system; this product does not include installation instructions or sealing materials.

• Use with female AN3 hose ends, lines or ports only
• Inspect threads and apply appropriate sealing method if required by system
• Have a trained technician verify torque and leak-free operation after install

Who is this for: This Podavelle AN3 male-to-male adapter pack suits mechanics, tuners and DIY enthusiasts fitting or repairing fluid lines on cars, motorcycles and motorsport projects. It’s ideal when you need a compact, corrosion-resistant connector that matches standard AN3 threading and tolerates fuel, oil, brake fluid and coolant. If you’re unsure about compatibility or proper installation, consult a professional installer or your vehicle’s system specifications before purchase.
