Msa Safety 458481 Plastic Smoke Tube Kit 6 Tubes

Product Description

The MSA SAFETY 458481 is a plastic smoke tube kit used to generate visible smoke trails for airflow testing, leak detection, and ventilation verification in HVAC and industrial environments. The kit includes a squeeze bulb, six replacement smoke tubes, and two end plugs, giving technicians everything needed to perform tracer smoke tests in the field. Smoke tubes are a standard diagnostic tool when verifying airflow direction, identifying drafts, locating air infiltration points, or confirming proper ventilation in confined spaces. This kit is suited for HVAC technicians, industrial hygienists, and safety inspectors who need a reliable, portable smoke generation solution.

This kit is commonly used in residential and commercial HVAC applications to verify airflow patterns around ductwork, grilles, and air handlers. It is also used in industrial settings to test local exhaust ventilation systems, fume hood performance, and general air movement. The squeeze bulb design allows controlled, low-volume smoke generation without powered equipment, making it practical for tight spaces and quick field checks.

Key Features

• Includes six smoke tubes for multiple tests per kit
• Squeeze bulb design allows manual, controlled smoke generation
• Two end plugs included for tube sealing and storage
• Plastic construction keeps the kit lightweight and field-portable
• Suitable for airflow direction testing, draft detection, and ventilation verification

Compatibility

Designed as a standard replacement smoke tube kit compatible with MSA SAFETY bulb-type smoke tube assemblies used in airflow and ventilation testing applications.

Installation Notes

Smoke tube kits are used by HVAC technicians, industrial hygienists, and safety professionals during system commissioning, inspection, or troubleshooting. Before testing, ensure the area is safe for smoke introduction and that any sensitive detection equipment is accounted for. Follow applicable OSHA and local ventilation testing guidelines when performing airflow verification in occupied or confined spaces. Dispose of spent tubes according to local regulations.
