Eaton Now Offers Hansen Fire-Rated (HKFR) Quick-Disconnect Hydraulic Couplings For Blow-Out Preventer Applications

Date: March 22, 2011

EDEN PRAIRIE, Minn. …Diversified industrial manufacturer Eaton Corporation today announced the availability of the HKFR-Series of fire-rated quick-disconnect hydraulic couplings for high-temperature, safety-related applications on oil and gas blow-out preventers (BOP). The HKFR-Series is part of Eaton’s line of Hansen® and Coupleurs Gromelle™ products which were acquired by Eaton in December, 2010.

Eaton’s HKFR-Series couplings meet the ISO 7241-1 Series B standard and carry a Lloyd’s Registry Certificate for the conditions stated in API 16D and EUB Directive 35.

“HKFR-Series couplings are engineered to perform in hazardous BOP service in the oil and gas industry,” said Brett Jaffe, couplings business director, Eaton. “Both the socket and plug are marked ‘BOP’ and the socket sleeve and wrench flats are red, all for easy visual identification after installation. Their dependable ball-locking mechanism connects and disconnects quickly without tools, so there is no risk of cross threading, and the standard sleeve lock prevents accidental disconnection.”

Eaton HKFR-Series couplings feature a two-way valve design that minimizes fluid spillage, and a very compact configuration that fits well into panels with limited space. They are available in four body sizes: ½” with a 7,000 psi (482 bar) working pressure and 28,000 psi (1,931 bar) burst pressure; and ¾”, and 1.0” with a 5,000 psi (344 bar) working pressure and 20,000 psi (1,379 bar) burst pressure. The 1.0” couplings are available in stainless steel.

Hansen couplings have been technology leaders since 1915 when Fred Hansen developed the first quick-disconnect coupling. As part of Eaton’s Hydraulics Group the products, technology, engineering, and manufacturing capabilities of Hansen and Coupleurs Gromelle significantly enhance Eaton’s ability to serve diverse hydraulic and pneumatic market needs.
