“Ultraflex” Ultra-flexible Liquid Cylinder Hose
The industry’s most flexible and durable hose for use with cryogenic liquid cylinders
Unisource Ultraflex Style UF21 liquid cylinder hose combines an ultra flexible design with high cycle life and extreme durability. |
|
Ultraflex UF21 construction starts with a special close pitch corrugated stainless steel. Corrugations are a unique disymetrical omega configuration, as opposed to the common U-shape corrugations that standard hoses have. The result is a hose unparalleled in ease of bending and cycle-life. Ultraflex UF21 carries an ISO 10380 rating of a minimum of 50,000 bending cycles. A low-profile, high coverage stainless steel braid provides high working pressures. An optional streamlined, highly flexible stainless steel armor casing covers the hose and provides kink resistance and protection for the braid. Special smooth stainless steel reducing collars are crimped over the armor and become a transition piece to the end fittings. Welded-on ends are machined from stainless steel bar stock as opposed to the thin wall flared tubing that most liquid cylinder hoses are constructed with. Flared ends have a smooth RA finish. Stainless steel nuts and flares are offered in either CGA295 or CGA440 style. Ultraflex UF21 hose is unaffected by cryogenic temperatures, and remains flexible in transfer applications. This hose carries a working pressure of 1160 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 Ultraflex UF21 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. |

CREATING A PART NUMBER FOR ULTRAFLEX LIQUID CYLINDER HOSE TO CREATE A PART NUMBER FOR THE DESIRED HOSE, USE THE KEY BELOW:
For example, for an assembly in the standard 1/2” I.D. size, with 3/8” MNPT one end and CGA440 (5/8) flare on the other end, complete with armor casing and cleaned, capped, and bagged for oxygen service would read as follows:
