QFS O-Ring

The QFS O-Ring is used with the Quick-Fit® Sleeve in Nordfab Sealed Duct systems.

- Performs well with many oils and chemicals.

- Temp range: -30° F to +225° F.

- 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.
