Podavelle 3AN Male to 3/8-24 Inverted Flare Adapter — 3/16" Brake Line, 304 Stainless, 2-Pack

Podavelle’s 3AN male to 3/8-24 inverted flare female adapter is a 304 stainless steel, two-piece fitting that converts 3/16" steel brake line terminations to -3 AN male connections for use with -3AN flexible hoses.

This compact adapter solves mismatched brake- and fluid-line fittings by giving a durable, corrosion-resistant junction between a 3/8"-24 inverted flare female end on 3/16" steel brake lines and -3 AN braided or flexible hoses. Machined from 304 stainless steel, each adapter includes an external groove for a retainer clip and resists common automotive fluids including brake fluid, fuel blends, oil and water. Professional installation is strongly recommended.

How does this adapter fit into a brake line or hose setup?

The adapter converts the factory 3/8"-24 inverted flare female termination on 3/16" steel lines into a -3 AN male flare connection. That lets you attach -3AN braided hoses or flexible lines to calipers, wheel cylinders or frame-mounted terminations without re-flaring or replacing the original steel line.

• Converts 3/8"-24 inverted flare female to -3 AN male.
• Designed for 3/16" steel brake line frame terminations.
• Works with -3AN flexible hoses to reach calipers or wheel cylinders.
• Includes an external groove for retainer clip mounting.

What materials and fluid compatibilities should I expect?

Podavelle adapters are machined from 304 stainless steel for strength and corrosion resistance in automotive environments. The metal choice balances durability with general corrosion protection for common vehicle fluids.

• Material: 304 stainless steel, corrosion-resistant finish.
• Compatible fluids: brake fluid, fuel, oil, unleaded petrol, methanol, and water.
• Suitable for environments where stainless corrosion resistance is preferred.

Will the adapter stay secure under road vibration and pressure?

The adapter includes a machined groove for a spring or retainer clip to lock it at a frame-mounted termination, helping prevent axial movement under vibration. When used with the correct clip and properly tightened hose fittings, it provides a reliable mechanical connection in brake and fluid systems.

• External groove accepts a retainer clip for secure mounting.
• -3 AN male flare provides a leak-resistant mating surface when properly tightened.
• 304 stainless construction resists galling and thread wear under repeated service.

Do I need special tools or skills to use these adapters?

Installation commonly requires basic flare-line handling, proper torque application, and a retainer clip for frame-mounted terminations. Because brake and fuel systems are safety-critical, professional installation is recommended to ensure leak-free, correctly torqued connections and system integrity.

• No instructions included; professional installation recommended.
• Requires compatible -3AN hoses and proper sealing practices.
• Use correct clip and torque values for safe operation.

Who is this for: These Podavelle adapters are intended for automotive technicians, fabricators and experienced DIY mechanics who need a reliable stainless-steel solution to convert 3/16" steel brake line terminations into -3 AN hose connections. They suit restoration projects, custom brake setups and performance builds where durable, corrosion-resistant fittings and the ability to use -3AN flexible lines are required. If you’re uncertain about fitting or torque procedures, have the adapter installed by a qualified technician to maintain vehicle safety.
