EVIL ENERGY Male 10AN Weld on Bung Fitting Stainless Steel

This two-piece set from EVIL ENERGY gives fabricators and vehicle builders a ready-made 10AN male flare interface for fuel, oil, coolant, or other fluid systems. Each bung is machined from 304 stainless steel, with a 37-degree AN sealing face and a 7/8-14 UNF thread to accept standard 10AN hoses and fittings. The components are rated for high pressure and a wide operating temperature range; they are intended for professional installation and require a cooling period after welding for best results.

How do these bungs form a leak-resistant AN connection?

The EVIL ENERGY bungs use a 37-degree flare surface to seal against AN fittings, a long-established mechanical sealing method in high-performance plumbing. When installed correctly, the flared AN fitting compresses against the precision-machined seat to form a metal-to-metal seal without washers.

• 37° AN sealing face machined into the AN side for consistent sealing
• 7/8-14 UNF thread matches standard 10AN male fittings
• 304 stainless resists corrosion that can compromise seals
• Requires correct torquing and professional installation for reliable sealing

What are the strength and temperature limits for these stainless bungs?

These fittings are built from 304 stainless steel and are rated to withstand system pressures up to 1000 PSI (68.94 bar). The operating temperature range covers many automotive and industrial applications, withstanding environments from below freezing to moderate heat.

• Maximum pressure: 1000 PSI (68.94 bar)
• Operating temperature range: -65°F to 252°F
• Material: corrosion-resistant 304 stainless steel for long service life
• Not intended for temperatures or pressures beyond listed ratings

How should these bungs be welded and prepared for use?

Welding these bungs into a tank or panel requires controlled heat input and good welding practice to preserve the machined sealing surface. After welding, allow the assembly to cool naturally for three hours before connecting AN fittings to avoid thermal distortion and ensure dimensional stability.

• Professional welding recommended to protect the sealing face
• Allow three hours of natural cooling after welding before use
• Inspect the 37° sealing surface for distortion or contamination prior to assembly
• Clean weld spatter and burrs that could interfere with the AN seal

Which thread and hose sizes are compatible with these bungs?

The threaded section conforms to 7/8-14 UNF, the standard thread for 10AN male fittings. This ensures direct compatibility with established AN hose ends and adapters commonly used in performance plumbing and custom fabrications.

• Thread size: 7/8-14 UNF for 10AN fittings
• Pairs with standard 10AN hose ends, adapters, and swivel nuts
• Designed for use with AN-style flared hose connections
• Confirm mating part specifications before final assembly

Who is this for: The EVIL ENERGY Male 10AN weld-on bung fitting 2-pack is made for experienced fabricators, race-car builders, and custom vehicle technicians who need reliable, corrosion-resistant AN ports in tanks, radiators, or bulkheads. It's ideal when a permanent, pressure-rated AN connection is required and the installer can weld and prep the sealing face properly.
