Our name says it all. Unisource is a complete source for all types of flexible hose metallic, PTFE, and thermoplastic. Since 1980, we have become one of the leading suppliers to the gas industry throughout North America. Our product line includes gas pigtails and liquid transfer hoses to accommodate all varieties of industrial, medical, and specialty gases in a wide range of pressure ratings. Unisource Manufacturing, Inc., based in Portland Oregon offers a broad array of special services to assure the highest product quality, backed by outstanding customer support. Unisource Offers these State-of-the-Art Products and Services: 1. The Highest Quality High-Pressure Cylinder Filling Hoses & Tube Trailer Hoses... PTFE Style Gas Pigtail PTFE or Teflon is chemically inert, virtually impermeable, and contributes to an extremely flexible and long-life product. Our PTFE pigtail products range from ratings of 3000 PSIG to 6000 PSIG maximum working pressure. Our TSCZ PTFE hose features a thicker inner wall with two stainless steel braids. These features reduce permeation dramatically, while improving pressure resistance. We offer brass or stainless steel permanently attached end fittings. All-Metallic, Welded Style Gas Pigtail Typically used for specialty, high-purity, or corrosive gas applications, all-metallic pigtails provide a zero-effusion solution. Products include corrugated interior core of 316L stainless steel or Monel, with multiple exterior stainless steel braids for pressure ratings as high as 4500 PSIG maximum working pressure. Fittings of 316L or Monel are permanently welded to provide a complete pigtail assembly. Thermoplastic Style Gas Pigtail Unisource thermoplastic pigtails are an economical choice for many types of industrial gases. Our thermoplastic hoses combine a Nylon or Polyester Elastomer Core with polyester reinforcing and perforated polyurethane cover. These flexible, lightweight, and durable hoses are available in standard 3000 PSIG maximum working pressure rating or in special order runs as high as 4500 PSIG maximum working pressure. Tube Trailer Hoses Our product line includes all-stainless steel, welded SF32HP 3700 PSIG maximum working pressure, and PTFE lined TSHP hoses for pressures to 5000 PSIG maximum working pressure. 2. Fittings Our standard 1/4 fittings are specially designed to meet ANPT specifications. ANPT (Aerospace Spec.) are machined to a much tighter tolerance than standard NPT fittings. Perfect for specialty gas applications, ANPT will ensure the highest leak integrity possible. 3. The Industry s Most Popular Liquid Cryogenic Hoses... For Liquid Cylinder Filling and Withdrawl Ultraflex all-stainless steel hose is the most flexible and easy to handle product in the industry. Our finest liquid cylinder hose, Ultraflex is ISO 10380 certified for cycle life. Superflex liquid cylinder hoses are our standard duty product. Both hoses are equipped with machined flare ends and optional armor casing. Bulk Cryogenic Hose Unisource bulk cryogenic assemblies are constructed with all-stainless steel corrugated hose, stainless steel braid, and welded stainless steel female NPT ends. CGA adapters can be added at customers request either threaded or silver brazed. Armor kink-resisting sleeves are added to each end of the assembly. 4. In-House O2 Cleaning and Testing... Unisource maintains control of all cleaning functions in our in-house cleaning facility. All cleaning and packaging is performed to C.G.A. standards. Cleaned hoses are clearly marked and tagged as cleaned for oxygen service. We hydrostatically test 100% of all high-pressure gas pigtails and tube trailer hoses to 1-1/2 times the rated working pressure of the hose. Specialty gas hoses are tested with high purity helium. Hoses are individually marked with working pressure, test pressure, and date tested. Mass spectrometer helium leak testing can be performed at customer request. All liquid cylinder hose and bulk cryogenic hose are pneumatically tested prior to final packaging.

Oxygen Service - A brass extension adaptor (BE-4-3HP) is recommended on all PTFE type hoses, to absorb the heat generated by adiabatic compression. Style TSC flexible pigtails have a minimum burst pressure rating 4 times the maximum working pressure. The stainless steel armor casing allows free movement of the hose and protects the hose from damage. This casing also acts as a bend restrictor to prevent kinking near the connections and to enhance whip protection in the event of a cylinder falling or other similar incidents. Oxy-Extension Piece BE-4-3HP is recommended in oxygen applications to absorb the heat experienced in adiabatic compression and eliminate possible damage to the PTFE tube if the pigtail is quickly pressurized with oxygen against a closed valve or regulator. 2

CO2 Bulk Liquid Transfer Rubber FDA Grade Hose Style 2520FDA Style 2520FDA hose is designed to handle the rigorous demands associated with the bulk transfer of CO2 liquid and vapor. Style 2520FDA hose outperforms all others. Each hose is constructed with a low temperature, smooth inner core (no more trapped CO2). Unlike rubber hydraulic hose that are constructed with carbon steel braids, Style 2520FDA hose is reinforced with stainless steel braids to resist carbonic acid corrosion. The rugged pin pricked outer casing will not bubble and is resistant to abrasion, ozone, and weather. Style 2520FDA hose is rated at 450 psig, and will operate from -65 degrees to +180 degrees F. A heavy duty brass FNPT fitting is attached to each hose end by use of a high temperature plated steel crimp collar that interlocks the two components.
