Advantage
Nitrile elastomers are resistant to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water, and alcohol, and maintain flexibility in low temperatures.

Instruction
The sealing gasket's cross-section is circular and round. Simple to use and easy to repair or replace.

NOTE:
Nitrile rubber is poor performance when exposed to sunlight, general weathering, and ozone. It is not suggested for outdoor applications.
