• 【Quality Craftsmanship】This is a weld-on half coupling, also known as a weld bung. Features a 1/2" Female NPT (National Pipe Taper) thread. The half coupling design allows for direct welding onto flat or curved surfaces of tanks, reservoirs, fuel cells, and containers, creating a permanent NPT port.
• 【Industry Standard】Constructed from Aluminum 6061-T6, this weld bung offers excellent strength-to-weight ratio, high corrosion resistance, and good weldability. The material provides a natural oxide layer that resists corrosion in harsh environments, making it ideal for fuel, oil, water, and chemical applications.
• 【Sealing Performance】The 1/2" Female NPT (National Pipe Taper) thread provides a standard, leak-resistant seal when used with compatible male NPT fittings and thread sealant (PTFE tape or paste). This allows you to easily screw in hose barbs, pipe nipples, plugs, sensors, or other accessories into the welded port.
• 【Easy Installation】Unlike threaded couplings that require external pipe threads, this fitting is designed to be welded directly onto your tank or container surface. Compatible with TIG welding (GTAW) process for aluminum. Provides a strong, permanent, leak-proof port for fluid transfer, venting, or draining applications. Professional welding required.
• 【Wide Applications】Ideal for custom fuel cells, hydraulic reservoirs, oil tanks, water tanks, chemical containers, diesel tanks, and industrial fabrications requiring a permanent NPT port. Each bung is precision machined for thread accuracy. We are confident in the quality and fit of our product.
