This hose assembly remains flexible in temperatures ranging from low cryogenic temperatures to 1,500 degrees F. It comes equipped with a factory-installed stainless steel male National Pipe Thread Taper (NPT) threaded connection on one end and a factory-installed stainless steel female NPT connection on the other. This hose is suitable for use in a wide range of applications, including medical, food transportation, electrical equipment cooling, and others.Industrial hoses and hose assemblies transfer or convey air or liquid in hose systems. When selecting industrial hoses or hose assemblies, use the STAMPED method to help determine the type of hose needed:S= Size (ID, OD, and length)T= Temperature (maximum and minimum temperatures of material being transported)A= Application (industry or process)M= Material (to be conveyed, type and concentration)P= Pressure (maximum working pressure)E= Ends (type of end connectors or couplings on hose)D= Delivery method (volume and velocity)The inside diameter of the hose must be adequate to keep pressure loss to a minimum and avoid damage to the hose due to heat generation or excessive turbulence. The hose must be capable of withstanding the minimum and maximum temperatures that occur within the hose system. Some applications require specialized oils or chemicals to be conveyed through the system. In this case, hose selection must ensure compatibility of the hose tube, cover, couplings and O-rings with the fluid used. Industrial hoses and hose assemblies are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.Unisource manufactures industrial, hydraulic, and sanitary hoses as well as expansion joints and braided connectors. The company, founded in 1980, is headquartered in Portland, OR. ## Features - Flexible stainless steel hose assembly for use in cryogenic liquid transfer operations - Corrugated 321 stainless steel tube for flexibility and resistance to extreme temperatures - Single-braid 300 series stainless steel reinforced cover for strength - Maximum temperature rating of 1,500 degrees F - One factory-installed stainless steel male NPT connection and one stainless steel female NPT connection ## Images ![Unisource SF21 Stainless Steel Flexible Metal Hose Assembly, 3/8" Stainless Steel NPT Male x NPT Female Connection, 1386 PSI Maximum Pressure, 30" Length, 3/8" ID - Image 1](https://images-na.ssl-images-amazon.com/images/I/91JDNWWVldL.jpg) ## Available Options This product comes in different **Maximum Pressure, Item Length String, Maximum bend radius, Outside Diameter, Inside Diameter String, Number of Items, Connector Type** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/92767380-unisource-sf21-stainless-steel-flexible-metal-hose-assembly-3-8](https://www.desertcart.tn/products/92767380-unisource-sf21-stainless-steel-flexible-metal-hose-assembly-3-8) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-10*
