حلقات O-Ring فيتون FKM | CS 0.103 بوصة × ID 0.424 بوصة | AS568-111 | داش 111 | متوافق مع FDA | صلابة 60 | أبيض (100 / عبوة)

Popped one of these onto a valve that sees constant 350°F steam and it hasn’t so much as softened after two weeks, which is more than the last batch could say. The white color made it easy to spot against the metal during install. For the price per hundred, these are a steal.

Finally found a white FDA-compliant Viton that holds up past 400°F without degrading. The 0.424" inner diameter fits my sanitary clamps perfectly, and the 60 durometer gives just enough give for a snug seal without being mushy.

The 60 durometer white Viton o-rings are noticeably stiff but seal perfectly against hot water lines in my brewing setup. These AS568-111 size rings fit snug and haven't deformed after several cycles up to 200°F.
