The standard jumpover configuration for steam service is a 3/4-in. hose (Type 321 stainless steel core covered by a Type 304 stainless steel braid) with a female JIC hydraulic connection on each end. Adapters are also provided for connecting the JIC hose fitting to standard 3/4-in. couplings on the jacketed piping or bolt-on heating jacket. Other hose sizes (1/2 and 1 in.) and connection configurations are available. CSI flexible jumpovers come pre-insulated with closed-cell, silicone sponge insulation good for temperatures up to 400°F. Flexible fiberglass insulating jackets for higher temperature service are available. Standard flexible jumpovers for hot oil service are 1-in. double-braided.
