Available Compounds

NBR Rubber

NBR is suitable for rubber grommets requiring oil resistance, abrasion resistance, and general industrial sealing performance.

Oil Resistant Abrasion Resistant General Use
EPDM Rubber

EPDM is commonly selected for grommets exposed to weather, ozone, aging, and moisture-related environments.

Weather Resistant Ozone Resistant Outdoor Use
FKM Rubber

FKM is used for grommets requiring strong resistance to heat, chemicals, oils, and fuels.

Chemical Resistant High Temperature Premium Grade
HNBR Rubber

HNBR provides improved heat, oil, and wear resistance compared with standard nitrile rubber, suitable for demanding protective applications.

Heat Resistant Oil Resistant Durable
Silicone Rubber

Silicone rubber offers excellent flexibility and temperature resistance, suitable for custom grommets requiring soft fitting and stable performance.

Flexible Temperature Resistant Soft Sealing
Fluorosilicone Rubber

Fluorosilicone combines low-temperature flexibility with improved fuel and oil resistance for specialty grommet applications.

Fuel Resistant Low Temperature Specialty Compound
Neoprene Rubber

Neoprene provides balanced resistance to weathering, abrasion, and mild chemicals, suitable for general-purpose rubber grommets.

Weather Resistant Abrasion Resistant General Purpose
SBR Rubber

SBR is a cost-effective material with good abrasion resistance, suitable for standard protective grommet applications.

Cost-Effective Abrasion Resistant Standard Use
ACM / AEM Rubber

ACM and AEM are suitable for automotive and industrial environments requiring heat and oil resistance.

Automotive Use Heat Resistant Oil Resistant
