John Crane Launches New 5610 Liquid Quench Seal with Flexibility to Cover More Applications

CHICAGO (November 11, 2021) — John Crane, a global leader in rotating equipment solutions, supplying engineered technologies and services to process industries, today announced the launch of its new 5610 Liquid Quench (5610L), which is an extension to the 5600 seal range.

  • Leverages the 5600 brand name and global recognition
