8" x 10" Replacement Gasket for Filter Holder SKU: TE-5018

The TE-5018 replacement gasket provides essential sealing for 8" x 10" filter holders used in high volume air samplers. This gasket ensures leak-proof operation in TSP, PM10, and PM2.5 sampling systems, maintaining the integrity of ambient air monitoring operations required for EPA compliance.

Compatible Systems and Applications

The TE-5018 serves as a replacement gasket for the TE-5035 adapter plate and works with multiple Tisch Environmental sampler configurations:

• TE-6000 Series PM10 systems with TE-6003 Stainless Steel Filter Holder
• TSP (Total Suspended Particulate) sampling systems
• PM2.5 monitoring applications requiring pre-separation stages
• High volume air samplers operating at 20-60 CFM flow rates

Maintenance and Replacement

Regular gasket inspection is essential — replace gaskets when they no longer seal properly to prevent sample contamination and maintain accurate flow measurements. The 8" x 10" dimensions match standard rectangular filter media used in ambient air quality monitoring.

During routine maintenance, inspect gasket surfaces for wear, cracking, or compression set that could compromise the seal. Proper gasket sealing provides leak-proof operation during the sampling process, ensuring regulatory compliance and data integrity.

Regulatory Context

This gasket supports EPA-compliant ambient air monitoring under 40 CFR Part 50, Appendix J for PM10 reference method sampling and related particulate monitoring applications. Proper sealing is critical for maintaining the chain of custody and data quality objectives required by environmental monitoring programs.
