features flexmaster joints in standard and self-restrained configurations standard features 1 gasket provides compression seal when tightened against tube or pipe 2 hinged coupling provides for quick easy assembly 3 bulged sleeve allows for ±4º angular misalignment all gasket materials listed on page 4 are available in the standard style increasing the number of suitable applications self-restrained features 1 gasket provides compression seal when tightened against tube or pipe 2 hinged coupling provides for quick easy assembly 3 bulged sleeve allows for ±4º angular misalignment plus 4 notched channel ring which grips pipe firmly to restrict movement along pipe or tubing gasket materials available include the c buna-n and d epdm compounds flexmaster joints are available in both standard and selfrestrained styles the self-restrained style has a stainless steel gripping ring inside each gasket this feature allows the joint to maintain a firm grip on the pipe or tube preventing movement along the pipe or tube the bulged straight-through flexmaster joints accommodate angular misalignment up to ±4º per end tees elbows and crosses accommodate angular misalignment up to ±2º per end see pages 10 thru 17 for the angular misalignment allowed on each specific part flexmaster joints are designed for up to 300 psi 2.07 mpa service depending on application and size refer to pressure ratings on page 4 flexmaster joints absorb vibration and are ideal for making quick connections and disconnections when repairing or disassembling a system they can be furnished with several types of gasket compounds and sleeve materials including stainless steel for marine and corrosive applications flexmaster joints are currently in use in thousands of applications throughout the world for typical flexmaster joint applications see photos on page 2 ii eaton hydraulics flexmaster joints catalog e-mefl-mr001-e1 may 2006

features save time make pipe and tube connection easier used on plain end tube or pipe no threading flanging welding grooving or other special end preparation of tube or pipe is required use pipe after it is cut to appropriate lengths the flexmaster joint will accommodate large tolerances in the length of the gap see table 1 page 9 for insertion depth tolerances absorbs vibration pipe vibration and noise can be drastically reduced with flexmaster joints the resilient thick rubber of the flexmaster joint gasket absorbs vibration and noise use of the self-restrained style restricts movement along vibrating pipes and tubes even misaligned piping is no problem the flexmaster joint design eliminates flanged bolt holes and pipe threads that require careful alignment the flexmaster bulged joint permits up to a total of ±4º angular installation misalignment at each end while maintaining a leakproof seal easy to install installation time can be slashed by using flexmaster joints basic assembly tools are all that s needed after extensive use the gaskets can be replaced easily and quickly see page 8 for complete assembly instructions eaton hydraulics flexmaster joints catalog e-mefl-mr001-e1 may 2006 1
