Refurbishing parts
Inspecting parts
Plastic parts: examine for cracking, softening or
discoloring. This may indicate chemical attack of
the material. Defective parts must be replaced.
Alternate material may be required. Contact
your supplier or Codeline for assistance.
Metal parts: check for corrosion, scratches,
dents, cracks or other damages to insert ring
and spiral retaining ring.
Other parts: examine for any damage, such as
gouges, chips or cracks that could affect
structural strength or sealing characteristics. The
following are some examples of defects that
may require replacement of the affected part.
End plug:
cracked, discolored, sealing areas damaged
(chipped or gouged), port threads stripped
or cross-threaded.
Spiral Retaining rings: are the sole means of
end plug retention. Parts bent, corroded,
cracked or damaged in any way must not be
used. Carefully check for hairline cracks.
