TE-1008-8 Silicone Filter Holder Gasket - 4½" OD for PUF Dual Module SKU: TE-1008-8

The TE-1008-8 is a silicone gasket with a 4½" outer diameter designed specifically for the 4-inch filter holder assembly in Tisch Environmental TE-1000 PUF (Polyurethane Foam) air samplers. This gasket provides the critical seal between the filter holder components in the upper chamber of the dual sampling module, ensuring leak-proof operation during particulate collection.

Technical Function

The gasket creates a leak-proof seal during the sampling process, maintaining proper airflow control and sample integrity. The upper chamber supports the airborne particulate filter media in a circular filter holder, and this gasket ensures no sample bypass occurs around the filter edges. Proper sealing is essential for accurate flow measurement and EPA-compliant sampling.

Key Specifications

• Material: Silicone rubber
• Outer diameter: 4½"
• Designed for 4-inch circular filter holders
• Temperature resistant for outdoor operation

Compatibility

This gasket is specifically designed for the TE-1008 4-inch filter holder assembly used in TE-1000 PUF air samplers that simultaneously collect suspended airborne particulates and trap airborne pesticide vapors. Compatible with:

• TE-1008 4-inch Filter Holder Complete
• TE-1002 Dual Sampling Module assemblies
• All TE-1000 series PUF air samplers
• Systems used for EPA methods TO-4A, TO-9A, and TO-13A sampling

Maintenance and Replacement

Regular gasket inspection is critical for maintaining sampling accuracy. Replace gaskets when they show signs of cracking, permanent deformation, or loss of elasticity. Periodic calibration is necessary to maintain on-site sampling accuracy, and worn gaskets can compromise system integrity. Silicone material provides excellent resistance to environmental conditions and maintains flexibility across temperature ranges typically encountered in ambient air monitoring.

Applications

Essential for PUF air samplers used in ambient air quality monitoring for volatile organic compounds and airborne pesticides. These systems are deployed for environmental monitoring, agricultural area assessment, industrial emission studies, and regulatory compliance monitoring where sampling must comply with U.S. EPA Method TO-4 for organochlorine pesticides and polychlorinated biphenyls in ambient air.
