The BuTech?FPSC6 is a precision-engineered O-ring check valve designed to offer reliable, one-way flow in high-pressure piping systems. Featuring 3/8" FNPT female connections and a Buna-N O-ring seal, it's rated to 15,000?psi (1,035?bar) for demanding industrial and hydraulic environments. Crafted from 316 stainless steel, the valve ensures robust corrosion resistance and long-term durability. Its compact cylindrical body and metal-to-metal seat design provide tight sealing and minimal pressure drop. Ideal for preventing backflow in pneumatic, gas, water, and instrumentation systems.
- 5,000?psi (1,035?bar) rated performance perfect for high-pressure applications
- 3/8" FNPT female female threaded connections for easy inline installation
- 316 stainless steel body ensures corrosion resistance and rugged durability
- Buna-N O-ring provides tight sealing with optional Viton, PTFE, or Kalrez alternatives available
- Compact design (?2.62" length, 1.00" hex) for installation in confined spaces
