The hose assemblies are supplied fitted with internal ballast weights and are designed to achieve neutral buoyancy in the liquid as the level of the roof changes. Clamping fixtures and support chains are supplied as part of the complete assembly which is shipped ready for installation.  CavMac offers alternative options for use with hydrocarbons with up to 50% aromatics and for liquids with up to 100% aromatics. The hose assemblies are also available with alternative end fixings such as built in or swaged type to suit customer preference.
