Product Overview | Flexible Braided Hoses
8773 Flexible braided hoses for gas, oil, steam, compressed air and oxygen service are ideal for applications requiring a high degree of flexibility with tightness and protection against burst- ing. They are used in piping systems to neutralize problems caused by vibration, thermal expansion, piping alignment and to accommodate motion. 8773 hoses are selected for use to accommodate angular, axial, offset, radial and random motions. Braided hoses are not to be compressed or stretched, select a hose long enough to allow proper flexing when accommodating axial movements. They are capable of handling high working pressures. The maximum working pressure is determined by the service temperature. Standard 8773 flexible hoses are for use up to 750 degree F temperature service. 8773-H (High Temp Hoses), are available for use up to 1000 degree F temperature service. There are various end types available, including nipple, flange, lap joint (floating) flange and welded pipe ends. All combinations of end types and lengths are available to be custom ordered to meet any application.
SPECIFICATIONS 8773 braided flexible connectors are available in ½ " through 12" nominal pipe sizes. Standard sizes 2" through 12" can be ordered with flanged ends. Screwed ends can be ordered up to 8". Materials of Construction Rolled and butt-welded, corrugated 321 stainless steel tubing incased in a 304 Stainless steel braid. The standard 8773 have carbon steel end connections and the high temperature 8773-H version have 304 stainless steel end connections. 8773-C oxygen service hoses also have 304 stainless steel ends and are factory degreased and cleaned for use with oxygen.
