The BuTech FPBF4 bulkhead coupling is a high-pressure fitting designed for sealing tubing through panels or enclosures. It connects two 1/4" FNPT female threads on either side of a bulkhead, offering a secure fluid path rated up to 15,000?psi (1,035?bar). Forged from cold-worked 316 stainless steel, the coupling provides outstanding corrosion resistance and structural strength. Its precision-machined construction ensures leak-tight performance and durable sealing in industrial, hydraulic, gas, and laboratory systems. Ideal for clean through-wall installations under challenging environments.
- 15,000?psi (1,035?bar) maximum pressure rating handles demanding service
- Connects 1/4" FNPT female threads both ends for bulkhead use
- 316 cold-worked stainless steel for corrosion resistance and strength
- Bulkhead nut provides reliable seal under vibration and pressure
- Perfect for industrial panels, enclosures, and instrumentation systems
