Close Bend Radius Blocks for HB632
These adapters are used when bends are needed close to
the end of the tube after the flare has been made, ferrule has
been pre-set, or flange has been made. For flared or Ferulok
fittings, attach tube end by threading tube nut onto the radius
block threaded pin. To use this block with Seal-Lok fittings,
Close Bend Adapters for Seal-Lok must be used to attach the
tube to the radius block.

Close Bend Adapters for Seal-Lok
These adapters are used when bends are needed close to the
end of the tube after the flange has been made or the sleeve
has been brazed onto the end of the tube.
HOW TO USE:
Screw the Seal-Lok adapter into the internal
thread* of the threaded pin on the radius block. Then attach
the flanged or brazed tube by threading the tube nut to the
Seal-Lok adapter on the radius block threaded pin.
*
If the threaded pin does not have an internal thread, a new threaded pin is required.
