0.139" CS × 1.609" ID حلقات O من السيليكون | AS568-223 | داش 223 | قابلة للكشف بالمعادن | صلابة 70 (22 / عبوة)

These o-rings fit perfectly on my high-temp steam valve, and the 70 durometer gives them just the right amount of firmness without being brittle. The 1.609" ID was dead on, so I didn't have to struggle to get them seated.

Installed these as gaskets in a steam manifold at work, and they seated perfectly without any binding. Even after repeated heating cycles they still hold a tight seal with no leaks.

The 450°F upper temperature range is exactly what I needed for a hot steam line repair. These 223-size rings seated perfectly on the first try and showed no distortion after a full cycle.
