Recommendations:
• To prevent band spreading, ensure that the tubing is fully bottomed in the fitting port before
tightening the compression screw.
• For easier accessibility, use compression fittings with long flats to attach tubes to the vent
valve.
• Perform the solvent manager leak test whenever you replace or loosen fittings during
maintenance (see the console online Help).
• Whenever you loosen fittings during maintenance, examine them for cracks, stripped threads,
and deformations.
• Do not reuse stainless steel fittings more than six times.
Required tools and materials
• Chemical-resistant, powder-free gloves
2.1.1 Assembling new fittings
For metallic (SST or MP35N) fitting assemblies with ferrules not previously assembled or set to
tubing, you must mark the compression screw and fitting body, and ensure that the two marks
line up when you tighten them.
Requirement:
Wear clean, chemical-resistant, powder-free gloves when performing
this procedure.
Required tools and materials
• 1/4-inch open-end wrench – For tightening or loosening stainless steel (gold-plated) fittings
with 2-piece ferrule.
• Permanent marker
• Chemical-resistant, powder-free gloves
To assemble the new fittings:
1.
Insert the end of a tube into the hexagonal end of the compression screw.
2.
Insert the tube into the larger end of the ferrule.
3.
Insert the tube into the fitting body.
4.
Rotate the compression screw, clockwise, into the fitting body until the screw is finger-tight.
5.
Using a permanent marker, mark the compression screw at the 12 o’clock position.
