RS PRO Silicon O-Ring O-Ring, 20.22 mm ID, 1.07 in OD

They're supplied in handy multipacks of 50 rings to ensure you have plenty on hand. As these rings are made from silicone, they're able to tolerate high levels of both hot and cold, so they're suitable for use across a broad operating temperature range. This resilient material is also resistant to weathering, meaning your seals will not be affected by exposure to air or sunlight. They can withstand a considerable amount of pressure thanks to the flexibility of the silicone, so they'll last a long time.

The silicone material is non-toxic and not dangerous to humans, making these O-rings well-suited to use on food production lines. Seals of this type are also common in aerospace and automotive applications.
