RS PRO Silicon O-Ring O-Ring, 6.07 mm ID, 0.375 in OD

These seals are made from silicone, a very flexible material that's long-lasting and capable of handling considerable levels of pressure. Silicone is also resistant to weathering, meaning the rings won't be damaged by sunlight or air exposure. They have a broad operating temperature range that enables them to withstand extreme conditions without loss of function.

As they're non-toxic, these silicone O-rings are a good choice for use in food processing lines. Seals such as these are commonly found in general engineering as well as in the automotive and aerospace industries.
