Create a robust, permanent, and leak-proof connection on any steel reservoir with the Buyers Products 3038686 Weld-On Steel Tank Flange. When building a custom hydraulic tank or repairing an existing one, securing reliable access points for fluid lines is paramount. This weld-on flange is engineered to become an integral part of your tank, providing a strong, threaded 2-inch NPT port that withstands the intense vibration, pressure, and demanding conditions of mobile and industrial hydraulic systems. Forget about bolt-on fittings that can loosen over time; this flange offers a permanent solution for professionals who demand uncompromising reliability and performance.
Unmatched Durability and a Perfect Seal
The 3038686 is forged from high-quality, raw weldable steel, ensuring maximum strength and perfect compatibility with any steel tank surface. Its thick, wide base provides ample surface area for a deep, penetrating weld, creating a bond that is as strong as the tank itself. This robust construction eliminates the common failure points associated with bulkhead fittings, such as stripped threads or loosening nuts, which can lead to costly leaks and system downtime. The internal 2-inch NPT (National Pipe Taper) threads are precision-machined to guarantee a tight, secure fit with standard pipes and fittings, providing a dependable seal for high-flow suction lines, return lines, or drain plugs.
Versatile for Countless Applications
This weld-on tank flange is an essential component for fabricators, mechanics, and equipment manufacturers across various industries. It is the ideal choice for creating ports on custom hydraulic reservoirs for dump trailers, wreckers, snowplows, and other work trucks. Its utility also extends to agricultural equipment, industrial power units, and custom fuel or water tanks where a durable threaded connection is required. Whether you are adding a main suction line, a fluid return port, a drain, or a filler neck, this flange provides the professional-grade foundation you need. As a leading manufacturer of truck and trailer equipment, Buyers Products ensures every component meets the highest standards of quality.
