- Buna-N, also known as nitrile rubber (NBR), is made of a synthetic rubber that has anti-microbial properties and is resistant to chemicals, oils, solvents, greases and petroleum-based fluids. It is resistant to abrasions, cuts, punctures, slashes and snags.
- Quattro cross-section shapes are four-lobed and feature a geometry with twice the number of sealing surfaces compared to standard O-rings. The ring is designed not to be able to twist and bend when the part moves since the cross section isn't round. They can perform at lower pressures than a standard O-ring increasing seal life.
