• To prevent band spreading, ensure that the tubing is fully bottomed in the fitting
before tightening the compression screw.
• For easier accessibility, use long compression screws to attach tubes to the
injector and 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 for cracks, stripped
threads, and deformations.
• Do not reuse stainless steel fittings more than six times.
