Podavelle 16AN Male Weld-On Bung Adapter Pack of 2 — 6061-T6 Aluminum, CNC-Machined

Podavelle 16AN male weld-on bung adapters are CNC-machined 6061-T6 aluminum fittings designed to provide a high-flow, leak-resistant tank or panel connection for fuel, oil, water, or air systems. These two 16AN (1-5/16x12UNF) male weld-on fittings arrive as a pack of two and are built for durable service where a welded, permanent port is required. Machined from lightweight 6061-T6 aluminum, each bung features a wide inlet with a deep taper to promote smooth fluid transition and a 37° AN sealing angle to ensure reliable sealing under pressure. They are intended for professional installation and are commonly used in custom tanks, fuel cells, oil pans, radiators, and other applications where a welded aluminum port is preferable.

How do these bungs improve flow and sealing compared with standard fittings?

The Podavelle 16AN bungs use a deep inlet taper that reduces turbulence as fluid exits the tank, improving flow efficiency. The 37° AN sealing surface is a standardized angle that mates cleanly with AN-style hoses and fittings to maintain a pressure-tight interface.

• Wide inlet and deep taper reduce flow restriction and promote smoother discharge
• 37° AN sealing angle provides consistent, leak-resistant mating with AN fittings
• CNC-machining delivers uniform geometry for predictable performance

What materials and construction quality can I expect?

Each bung is machined from 6061-T6 aluminum, a material known for its favorable strength-to-weight ratio and corrosion resistance when used with non-corrosive fuels and fluids. The CNC process ensures precise threads and sealing surfaces so the fittings seat correctly with mating hardware.

• 6061-T6 aluminum body for lightweight durability
• Precision CNC machining for accurate thread and taper dimensions
• Pack of two bungs for multi-point installations or spares

Where should I use these weld-on bungs and what installation considerations matter?

These bungs are intended for permanent welded installations on aluminum tanks, oil pans, valve covers, radiators, fuel cells, and similar components. Because they must be welded, professional welding and leak-testing are strongly recommended to ensure a safe, durable seal compatible with the intended fluid.

• Designed for weld-on installation into aluminum components — do not use without welding
• Suitable for fuel, oil, water, air, and other compatible fluids (verify compatibility with fuels/additives)
• Professional welding and post-weld inspection recommended for pressure applications

Will these fit my existing AN hoses and what size are they?

These are 16AN male fittings, corresponding to a 1-5/16x12UNF thread specification. They are made to accept standard AN-style mating hardware and hoses sized for 16AN connections when paired with appropriate AN nuts and seals.

• Marked 16AN, 1-5/16x12UNF male thread — standard for 16AN systems
• Requires matching 16AN female hose ends or adapters for connection
• Ensure correct thread engagement and sealing hardware during assembly

Who is this for These Podavelle 16AN weld-on bungs suit fabricators, racers, performance builders, and mechanics who need durable, high-flow welded ports on aluminum tanks and components. If you are designing or modifying fuel cells, oil pans, radiators, valve covers, or custom fluid systems and you require a permanent, AN-compatible inlet or outlet, this pack of two precision-machined fittings offers a lightweight, industry-standard solution. Note: this product requires welding and professional installation; it is not a push-fit or drop-in part.

FAQ

Q: Do these 16AN bungs require welding?

A: Yes, these fittings must be welded to the tank or panel; professional welding is recommended for leak-free performance.

Q: Are these compatible with standard 16AN hoses?

A: Yes, they are 16AN male (1-5/16x12UNF) and mate with standard 16AN female fittings and hoses.
