Sealing Performance & Function

Seals and gaskets are engineered to maintain controlled sealing under defined operating conditions, including pressure, temperature variation, and exposure to fluids or gases.

Material selection and component design are based on sealing requirements, compression behavior, and long-term performance in the intended environment.

Static sealing for fixed interfaces

Dynamic sealing for moving components

Resistance to fluid and gas leakage

Compression and recovery characteristics

Performance under thermal and pressure variation

Material Selection for Sealing Applications

Material selection is based on operating conditions, chemical exposure, sealing requirements, and mechanical performance.

HTEI selects elastomer compounds to ensure compatibility with the application environment and long-term sealing performance.

NBR / HNBR for oil and fuel resistance

EPDM for water, steam, and weather exposure

FKM (Viton®) for high temperature and chemical resistance

Silicone for temperature stability and medical applications

FFKM for extreme chemical and thermal environments
