حلقات O من Viton FKM بقطر داخلي 0.103" × 1.674" | AS568-131 | Dash 131 | صلابة 75 | بني (70 / عبوة)

Needed to replace some old o-rings that kept failing on a hot oil line, and these Viton seals have held perfectly with zero leaks so far. The -15°F to +400°F rating gives me confidence they'll handle both peak heat and cold starts.

The 75 durometer hardness is exactly what I needed for a snug fit in my hydraulic fitting, and the brown Viton handles the 300°F heat without any deformation. Package of 70 gives me plenty of spares for the price.

I’ve been using these o-rings in a high-heat application near a furnace and they haven’t degraded at all, which is a huge relief. The -15°F to +400°F range gives me confidence they’ll hold up in extreme conditions.
