2. Installation Instructions:
Apply a non-hardening lubrication to the threads on both ends of the
flexible fitting. Killark’s thread lubricate “LUBG or LUBT” is
recommended. Other certified lubrications or petroleum jelly may be
used.
Thread one end of the flexible fitting into the correct size NPT female
opening or male nipple until hand tight plus one turn minimum with a
wrench. At this point the flexible fitting will no longer be able to be turned.
The opposite end will require a certified union or un-poured sealing fitting
threaded onto it, again, until hand tight plus one turn minimum with a
wrench.
When installing the flexible fitting ensure that all bends are not less than
the minimum bend radius allowed. Refer to the catalog for the radii of
the flexible fittings.
