O-ring, 85 x 3 mm - Viton, Part# 980333

O-ring, 85 x 3 mm - Viton, Part# 980333
This is an O-ring that measures exactly 85mm inside diameter and 3mm thick. That is the size written as 85 x 3 mm. It fits into a groove between two metal parts. When you tighten everything up, the O-ring squishes just a little bit. That squish creates an airtight seal. No air gets in. No oil gets out.
This O-ring is made from Viton, which is a type of FKM rubber . Why does that matter? Because regular rubber cannot handle the heat inside a vacuum pump. It also swells up when it touches oil.
Viton is different. It stays flexible even when things get hot. It resists oil and chemicals without breaking down. It works in temperatures from about -15°C up to +200°C (that is 5°F to 392°F). That makes it perfect for pumps that run all day long.
