Overview
The Parker PGI AK-022-C0 is a stabilized connector flange kit engineered for high-pressure instrumentation applications. Built from ASTM A743-316 stainless steel, this kit delivers robust pressure handling and corrosion resistance in demanding flow measurement systems. The stabilized design minimizes vibration and deflection, ensuring reliable connections between instrument manifolds and orifice plate assemblies across refinery, petrochemical, and pipeline operations.
Key Features
- 316 Stainless Steel Construction: ASTM A743-316 stabilizing connector and stabilizing foot for superior corrosion resistance
- High Pressure Rating: 10,000 PSI @ 200°F and 8,000 PSI @ 450°F maximum
- Complete Kit Assembly: Includes stabilizing foot, 1-1/2″ hex nut, 7/16-20 x 1″ mounting bolt, and Teflon flange seal
- Stabilized Design: Integrated stabilizer foot reduces connector deflection and vibration during high-pressure transients
- Nace-Compliant: Meets NACE MR0175/ISO 15156-3 requirements for sour service applications
