For 43 years, one rule remains unbroken: We only produce high quality oil seals.
Every day, we test materials, measure tolerances, verify pressure limits, and refine processes—
so your equipment runs longer, and you sleep better.
Thermoplastic Elastomers are measured in Shore A and Shore D according to ISO 868. Shore hardness is a measure of the resistance of a material to the penetration of a needle under a defined spring force. It is determined as a number from 0 to 100 on the scales A or D. The higher the number, the higher the hardness. Shore hardness reduces as temperature rises.
