  • Field-proven performance since the invention of the Grayloc clamp connector in 1951

  • Regional engineering, manufacturing, and sales facilities offer worldwide product and project support

  • Fully-accredited ASME/ISO quality management systems provide 100% traceability of all components

Grayloc connections enable design optimization, cost efficiency, and reduced installation and maintenance times.

  • Reduced maintenance with leak-free, field-proven design
  • Conserves space and reduces weight with compact footprint
  • Faster installation, assembly, and disassembly
  • Incorporates easily serviceable and reusable components
  • Minimizes spare parts inventory

Our products are suitable for use in extreme service conditions.

  • Vibration: 80 to 200 cycles per second under 6,600 psi
  • High temperature: Service experience to 1,700 °F  (926 °C)
  • Low temperature: Routine liquefied gas service, including liquid hydrogen and nitrogen, to -425 °F (-254 °C)
  • Thermal shock: Routine service with temperature changes up to 300 °F (149 °C) per hour
  • Corrosion: Liquid sodium service at 1,200 °F (649 °C)
  • Leak rate: 10-6 atm cc/s helium
  • Pressure: Full vacuum to 60,000 psi
Our standard Grayloc product lines include clamp connectors, compact flanges, closure systems, and remote connectors. A full suite of piping components that complement these technologies is available, ranging from threaded fittings, crossover components, and integrated pipe fittings, to metering solutions, ball joints, and check valves.
