Cryogenics

The very first HILTAP connector was used as a liquid nitrogen transfer coupling replacing a flange, in a 'freeze plug' procedure in a nuclear plant's reactor heat exchange piping.

HILTAP's features offered then and continue to offer;

• low torque / hand tighten-able connect-ability
• metal to metal sealing
• repeatedly reusable seals
• dead tight sealing
• safely locks under residual pressure

HILTAPâ™s cryogenic ultra tight connection experience includes;

• liquid / gaseous nitrogen
• liquid / gaseous hydrogen
• liquid / gaseous oxygen
• liquid / gaseous carbon dioxide

Applications include ;  space simulation chambers, piping connections, hose connections liquid & gas transfer, quick access closures, etc.

HILTAP's latest couplings are used in cryogenic temperature control transportation applications, new features include:

• positively locks the hose half on the truck/rail side half with no emissions should  any upstream valves fail open.
