and 424 Bender – Close Bend Radius Blocks
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.
