Why Tank Cap Integrity Matters

The tank cap assembly forms a critical seal in the dust collection system. A cracked, worn, or missing cap allows air bypass — reducing suction efficiency and risking dust leakage at the collection point. Replacing with a genuine OEM part ensures the correct fit and seal specification every time.

Protect Suction & Containment

Don't let a small component compromise a high-value machine. A proper tank cap seal is essential for maintaining the negative pressure that makes your dust extractor effective — and for keeping collected material contained during transport and disposal.
