A flange is a protruding rim, edge, rib or collar, as on a wheel or a pipe shaft. Flanges are used to strengthen an object, hold it in place or attach it to another object. Hydraulic flanges provide leak-free connections for hydraulic hose, pipe and tube assemblies. These flanges ensure leak proof joints under severe working conditions.
Hydraulic flanges are mainly 4-bolt flanges available in standard
configurations of split flange that is comprised of two separate flange
halves and captive flange is a one-piece flange. The bolt-hole
dimensions for these flanges are size-for-size identical. Flanges with
flareless fittings type can be used as a conversion fitting and thus
make piping easy and clean.
