Groth Corporation Model 12-TH Thief Hatch (for Steel or Fibreglass FRP Tanks)
Groth Corporation Model 12-TH Thief Hatch is for use on steel or fiberglass (FRP) low pressure oil tanks utilizing the eight inch round API 12 bolting pattern.
Designed to protect low pressure oil storage tanks, with industry leading high flow rates, and precision tolerances to provide superior sealing performance. The leakage is less than 1 SCFH of air @ 90% of the set pressure, keeping your tanks in compliance with industry standards. We were able to accomplish a product design with both superior sealing performance and industry leading flow rates. We paid high attention to detail in the precision machining and manufacturing to accomplish these exact tolerances. The Groth Model 12-TH Thief Hatch is available in a wide range of pressure settings and vacuum settings.
