2022 PRODUCTS CATALOG - INDUSTRIAL HOSE, COUPLINGS AND EQUIPMENT

HOW TO USE THE COUPLINGS SECTION Couplings are designated by Numbers, and are described as to construction and source. Adapters and fittings are available for special applications. The proper clamp size should be selected carefully, since many clamps will fit only one hose size or a narrow range of sizes. For certain critical fluids, specific couplings are used, as follows: CRITICAL APPLICATIONS 1. Use only the couplings recommended in this catalog for conveying: ■ Steam ■ LP Gas ■ Corrosive Chemicals ■ Edible Products ■ Petroleum Products 2. For conveying flammable fluids, use couplings made of nonsparking materials, such as brass or aluminum. 3. For ground fueling of aircraft, use certified coupled assemblies only. When you have selected a hose from the Hose Section, you will have found one or more coupling recommendations for that hose. The following procedure will help you make the final selection: A. If more than one coupling is recommended, make a final selection for type of coupling on basis of cost, sizes available, thread type available and application. B. Determine how the coupling is to be fastened to the hose – crimp sleeve, ferrule, band or clamp. NOTE: Because the hose/coupling interface is critical to hose assembly performance, always follow the specific instructions of hose and coupling manufacturers regarding the match of hose/fittings and assembly procedures. Trained personnel using proper tools and procedures should make hose assemblies. Failure to follow hose and couplings manufacturers’ instructions or failure to use trained personnel might be dangerous and could result in damage to property and serious bodily injury. .
