dust-tight
Definition
Adjective
- Resistant to the passage of dust: "dust-tight" describes a seal, enclosure, or container designed to prevent dust from entering or escaping. It is often used in engineering, electronics, or industrial contexts to specify a high level of protection against particulate matter.
Usage Examples
- (The casing prevents dust from reaching the electronics.)
- (The enclosure is sealed against dust ingress.)
Advanced Usage
- "dust-tight seal": a joint or closure that blocks dust completely.
- The machine's motor has a dust-tight seal to ensure long-term reliability. (The seal prevents dust from damaging the motor.)

Notes
- "Dust-tight" is a technical term commonly found in specifications for enclosures (e.g., IP6X rating in the Ingress Protection code). It is not used in everyday conversation but is precise in industrial, electrical, or mechanical contexts.
