The Bona Dust Tube O-Ring 44.2 × 3 mm is a genuine Bona replacement seal for the dust tube assembly on the older Bona Standard Edge family of edging sanders.
This small but important seal helps create a secure connection around the dust tube, reducing unwanted air and dust leakage and supporting effective dust collection during professional floor sanding.
Professional Advice from Wiltshire Wood Flooring Supplies:
The older Bona Standard Edger has been sold under several different names,
including the Bona Standard 220, Standard 2.2, Edge XL and Viking. Although
the machine name may differ, these models form part of the same Standard
Edge family.
O-rings can become flattened, hardened, split or damaged through age, heat and exposure to fine sanding dust. Replacing a worn seal helps maintain a secure dust tube connection and reduces dust escaping around the joint.
