Which fitting attachment method is best for Teflon hose assemblies, crimping or swaging?
In the end, the most important factor is whether or not the finished assembly performs to the accepted industry standards. Both methods are used successfully when fabricating qualified aerospace and industrial assemblies. However there are several advantages to the crimping, lower tooling costs, ease of assembly, faster production rate, scrap reduction, etc… Therefore crimping is the more widely used. What is the difference between dash and true bore sizes. Dash size is common terminology used to refer to the inner diameter of a hose. This was a system developed to identify the hose size in a part number. A two digit number is used to represent the relative I.D. in sixteenths of an inch. However, dash sizes do not match to the actual inner dimension of the hose. The actual I.D. is smaller. For example, -04 hose has an actual I.D. of .187, -05 hose has an actual I.D. of .250. If the exact inner dimension is required be sure to ask for true bore hose size. This can cause some confusion b
