-10 Welding Bung 7/8

The -10 Welding Bung 7/8 from XRP-XTREME RACING PROD. is a precision-engineered weld-on adapter designed for high-performance fuel system plumbing and custom automotive hydraulic applications. Built for serious engine builders, fabricators, and motorsport enthusiasts, this aluminum welding bung provides a secure, leak-free termination point when you need to cap off or transition -10 AN lines without running them to an active component. Whether you're finalizing a custom fuel rail, sealing a pressure line on a dry-sump system, or finishing a billet manifold installation, this bung eliminates the need for bulky external plugs and delivers a clean, integrated aesthetic.

Manufactured from aerospace-grade aluminum in natural (uncoated) finish, the -10 Welding Bung 7/8 features a female O-ring port and a 7/8-inch weld neck designed for permanent tig or mig welding directly into aluminum or steel manifolds and tanks. The O-ring seal accommodates standard -10 AN hose and fittings, allowing for future fluid routing flexibility without sacrificing structural integrity. At just 0.12 lbs with compact 2.75 x 1.1 x 3.7-inch dimensions, this bung integrates seamlessly into tight engine bay layouts. XRP's reputation for precision AN plumbing components ensures concentric bore alignment and consistent weld surfaces that professional shops and OEM suppliers depend on.

This welding bung is ideal for vintage hot rod restoration, turbocharged EFI conversions, race car fuel system modifications, and custom marine engine installations where code-compliant, permanent fittings are mandatory. Engine builders working with billet blocks, aluminum heads, and custom-fabricated fuel rails will appreciate the seamless integration and elimination of external bulk. Installation requires intermediate welding skill and heat management to avoid O-ring damage during the welding process; allow proper cooling before pressurization. Compatible with all -10 AN hose, hard line, and fitting standards, this single-unit bung is an essential component for anyone building a professional-grade custom fuel or hydraulic system.
