Hammer Lug Hose Swivels

The Hammer Lug Hose Swivels are designed to relive torsion high pressure hoses that are used for hook-up of different high pressure systems in Choke & Kill and cementing systems.

The swivel is manufactured in high strength Alloy or carbon steel, or stainless steel. Seal rings have high temperature and high pressure capacity, and very low friction.

Together with hardened raceways this gives very low rotation resistance at rated working pressure, effectively enabling the main purpose of the swivels; to relive torsional loads in the hoses and fixed end connections.

The swivels have type approval from DNV.
