Swagelok SS-645-FPAR Stainless Steel High-Pressure Manifold

Swagelok SS-645-FPAR is a high‑pressure needle valve from the Sno‑Trik line, engineered in 316 stainless steel for precise flow control in demanding pressurized systems. This angle‑pattern, replaceable-seat valve features 3/4‑16 in. connections and is rated for working pressures up to 45,000 psi (3100 bar), with a temperature range up to 1000°F (537°C), making it suitable for high‑temperature, high‑pressure gas and liquid lines in instrumentation and calibration work. The SS-645‑FP variant is designed for replaceable seating, with the SS‑645‑RS‑64F seat option available for service without replacing the entire valve. Swagelok factory tests every high‑pressure needle valve to ensure performance and reliability in laboratory and industrial environments, and the 645 family is explicitly described as an angle‑pattern high‑pressure needle valve within the Sno‑Trik lineup. This part is manufactured by Swagelok and represents a robust solution for metering and regulating flow in critical applications where precise control at extreme pressures is required.
