Shand offer a range of swage fittings suitable for internal or external swage as well as crimping. Our fittings are available in a range of materials and with a number of end connections. Please send your enquiry through to us and we will be happy to quote or help with technical questions.
Internal Swaging is the process by which the stem is internally expanded to compress the hose material against the ferrule to provide grip.
Internal swaging also provides a full flow area through the bore of the stem significantly reducing turbulence and the possibility of bacteria becoming trapped between the end of the stem and the hose. This is particularly suitable for food grade hose assemblies.
Internal swaging is achieved by pulling a hardened tool of larger diameter, (commonly known as 'dolly') down the inside of the stem in order to expand it. The compressive force exerted on the hose by the stem causes the hose material to flow into the serrated cavities of both stem and ferrule thus providing a secure mechanical bond.
External Swaging is the reverse of internal swaging in that it is the act of compressing the ferrule onto the hose material in order to compress it against the stem to provide grip.
External swaging is achieved by pushing the hose and end fitting assembly through a hardened steel die whose inside diameter is smaller than the external diameter of the ferrule.
Similar in principle to internal swaging, the external diameter of the ferrule is permanently reduced such that the resulting compressive force exertedonto the hose causes it to flow into the serrated cavities of both stem and ferrule thus providing a secure mechanical bond.
Combination Swaging is effectively the same as external swaging except that the stem and the ferrule are welded together instead of the ferrule being held on the ferrule behind a retaining ring.
The benefit of combination swaged fittings is one of cost as they are more easily manufactured than an equivalent external swage fitting.
