The QFS O-Ring is used with the Quick-Fit® Sleeve in Nordfab Sealed Duct systems.
- Performs well with many oils and chemicals.
- Can’t be damaged by flexing and twisting.
- Used in conjunction with Nordfab’s standard Sleeve O-ring. IT DOES NOT REPLACE IT.
Nordfab offers QFS Sealed Duct to protect against leakage in ducting used in ventilation systems where oil mist and smoke are contaminants.
