Style SF21 is an economical standard-duty liquid cylinder hose. High-pressure rated, with good flexibility and durability. Flared ends have a smooth RA finish. Stainless steel nuts and flares are offered in either CGA295 or CGA440 style.
This hose carries a working pressure of 1330 PSIG—far beyond the operating pressures of standard liquid cylinder. Each hose assembly is individually leak tested. The stainless steel collar is stamped with the manufacturer, pressure rating, and date.
All Superflex SF21 liquid cylinder hoses can be cleaned for oxygen service. Unisource maintains an on-site cleaning facility that cleans, marks, inspects, and packages assemblies to the requirements of CGA G-4.1. Standard assemblies are 1/2-inch I.D., but are available in several other sizes. Options include male NPT 3/8” or 1/2” fittings, or 90-degree stainless steel elbow end with flare. Pressure relief tubes with 1/4-inch FNPT port can also be permanently welded to the assembly. Accessories include male x female 90-degree cryogenic elbows, heavy-duty bronze phase separators, safety relief adapters, and quick-fill T-handle spin adapters.
