O-Ring Set for TE-20-800 Series 8-Stage Cascade Impactors - 11 Piece Kit
Complete set of 11 precision silicone o-rings designed specifically for the TE-20-800 series eight-stage Andersen cascade impactors. These seals ensure proper stage-to-stage integrity during particulate sampling operations, preventing air leaks that could compromise sample accuracy and flow rate control.
The TE-20-800 cascade impactor utilizes precision-machined aluminum stages with successively smaller hole diameters, requiring proper sealing between each stage for accurate particle size separation. The silicone o-rings provide corrosion resistance and maintain seal integrity throughout the impactor's operating range.
Key Specifications
- Set of 11 o-rings for complete impactor assembly
- Silicone construction for chemical resistance
- Designed for 28.3 ALPM operating flow rate
- Compatible with ambient temperature sampling conditions
Compatibility
This o-ring set is specifically designed for use with:
- TE-20-800 Eight-Stage Non-Viable Andersen Cascade Impactor
- TE-20-800 series impactors with standard aluminum stage construction
- Systems operating at the standard 28.3 LPM flow rate
Not compatible with viable impactor models or modified high-flow configurations without verification of seal dimensions.
Maintenance Guidelines
Replace o-rings when visual inspection reveals cracking, hardening, or permanent deformation. Proper sealing maintains the ± 1.5 ALPM flow rate tolerance required for accurate aerodynamic particle separation. Inspect seals before each sampling campaign and replace as needed to ensure EPA-compliant data quality.
During installation, apply a thin layer of compatible silicone lubricant to prevent pinching and ensure proper seating in the stage grooves. Tisch Environmental recommends keeping spare o-ring sets available for field replacement during extended sampling operations.
Applications
Essential for maintaining proper size separation from >10μm to <0.4μm particles in ambient air quality monitoring, source emission testing, and aerosol characterization studies. Critical for maintaining data integrity in EPA compliance monitoring and research applications requiring precise particle size distribution measurements.
