Several typeand sizes of type QRC-FG couplings have been certified by Lloyd’s Register in accordance with specification 16 D of the American Petroleum Institute (API) and with directive 36 of the Alberta Energy and Utilities Board (EUB), which establish design standards for systems used to control blowout preventers (BOPs) and associated valves that control well pressure during drilling operations.

The specification API 16 D and EUB directive 36 require STAUFF type QRC-FG flat-face hydraulic screw-to-connect couplings to be tested at 700° C fire exposure for at least 5 minutes at specific rating pressure of 345 bar without loss of pressure or leakage. It is often referred to as the “fire safe” rating for hydraulic couplings.
