glossary a alpha/numeric b backing a soft rubber layer between a hose tube and/or cover and carcass to provide adhesion barb the portion of a fitting coupling that is inserted into the hose usually comprised of two or more radial serrations or ridges designed to form a redundant seal between the hose and fitting barbed and ferrule fitting a two-piece hose fitting comprised of a barbed insert nipple normally with peripheral ridges or backward-slanted barbs for inserting into a hose and a ferrule usually crimped or swaged barb-titetm a line of low pressure push-on brass hose end fittings that is a trademark of dana corporation bend radius the radius of a bent section of hose measured to the innermost surface of the curved portion bend radius minimum the smallest radius at which a hose can be used for metal hose the radius of a bend measured to the hose centerline as recommended by the manufacturer blister a raised area on the surface or a separation between layers usually creating a void or air-filled space in a vulcanized article blow out force the force generated from the internal pressure attempting to push the fitting from the hose body wire normally a round or flat wire helix embedded in the hose wall to increase strength or to resist collapse bore 1 an internal cylindrical passageway as of a tube hose or pipe 2 the internal diameter of a tube hose or pipe bosflex a/w® a product s name for an air and water hose that is a registered trademark of dana corporation braid the woven portion of a hose used as reinforcement to increase pressure rating and add hoop strength various materials such as polyester cotton or metal wire are used a hose may have one or more braids outside or between layers of hose material braid wear motion between the braid and corrugated hose which normally causes wear on the outside diameter of the corrugation and the inside diameter of the braid braided ply a layer of braided reinforcement braid-over-braid multiple plies of braid having no separating layers brand a mark or symbol identifying or describing a product and/or manufacturer that is embossed inlaid or printed brass a family of copper/zinc alloys brazing a process of joining metals using a non-ferrous filler metal having a melting point that is lower than the parent metals to be joined typically over +800ºf bronze an alloy of copper tin and zinc bspp/bspt british standard pipe parallel british standard pipe tapered see fitting/coupling pipe thread fittings c carcass the fabric cord and/or metal reinforcing section of a hose as distinguished from the hose tube or cover abrasion external damage to a hose assembly caused by its being rubbed on a foreign object a wearing away by friction abs air-brake swivel absorption regarding hose the process of taking in fluid hose materials are often compared with regard to relative rates and total amounts of absorption as they pertain to specific fluids acid resistant having the ability to withstand the action of identified acids within specified limits of concentration and temperature adapter adaptor 1 fittings of various sizes and materials used to change an end fitting from one type to another type or one size to another i.e a male sae to male pipe adapter is often attached to a female sae to create a male end union fitting 2 the grooved portion of a cam groove coupling adhesion the strength of bond between cured rubber surfaces or between a cured rubber surface and a non-rubber surface adhesive a material which when applied will cause two surfaces to adhere ambient temperature the temperature of the atmosphere or medium surrounding an object under consideration ambient/atmospheric conditions the surrounding conditions such as temperature pressure and corrosion to which a hose assembly is exposed amplitude of vibrations and/or lateral movement the distance a hose assembly deflects laterally to one side from its normal position when this deflection occurs on both sides of the normal hose centerline anchor a restraint applied to eliminate motion and restrain forces annular refers to the convolutions on a hose that are a series of complete circles or rings located at right angles to the longitudinal axis of the hose sometimes referred to as bellows anodize anodized an electrolytic process used to deposit protective or cosmetic coatings in a variety of colors on metal primarily used with aluminum ansi american national standards institute application working pressure unique to customer s application see pressure working application the service conditions that determine how a hose assembly will be used armor a protective cover slid over and affixed to a hose assembly used to prevent over bending or for the purpose of protecting hose from severe external environmental conditions such as hot materials abrasion or traffic assembly a general term referring to any hose coupled with end fittings of any style attached to one or both ends astm american society for testing and materials attachment the method of securing an end fitting to a hose e.g banding crimping swaging or screw-together 2 piece or 3 piece-style field attachable fittings axial movement compression or elongation along the longitudinal axis 278
