Nitrile Rubber Ring (NBR):
NBR is commonly used for sealing applications due to its excellent resistance to oil, fuel, and other petroleum-based fluids.
It offers good resistance to abrasion and tearing.
Suitable for moderate temperatures and pressures.
Check compatibility with the fluids and temperatures present in your application.

Silicone Rubber Ring:
Silicone rubber has excellent resistance to extreme temperatures, both high and low.
It is known for its flexibility, durability, and resistance to ozone and UV light.
Ensure compatibility with the chemicals and temperatures in your application.
Silicone rubber may not be suitable for applications involving certain hydrocarbon-based fluids.

PTFE (Polytetrafluoroethylene) Rubber Ring:
PTFE offers exceptional chemical resistance, including resistance to most acids, bases, and solvents.
It has a wide temperature range and is suitable for both high and low temperatures.
PTFE is non-reactive, making it suitable for use in various industries, including food and pharmaceutical.
Ensure proper sizing and compression to achieve a reliable seal.

Fluoro Rubber Ring (FPM or FKM):
Fluoroelastomers such as FKM or FPM offer excellent resistance to high temperatures and a broad range of chemicals.
