حلقات O من Viton FKM 0.139" CS × 6.359" ID | AS568-261 | داش 261 | صلابة 75 | بني (12/عبوة)

Replaced the worn seals on a hydraulic line rated for high heat, and the 75 durometer hardness feels plenty sturdy for the job. They slid on without any stretching or tearing, and the brown color makes them easy to spot during assembly. Exactly what I needed for the -15°F to 400°F range.

Finally an o-ring that actually handles the heat without melting into a gooey mess. The 400°F rating is no joke—I've had these on a steam line for weeks and they're holding their shape perfectly. The brown Viton material feels dense and solid, exactly what I needed for this high-temp application.

These fit perfectly on my industrial valve cover and the brown color makes them easy to spot during maintenance. They sealed nicely right away with no leaks, exactly what I needed for a high-heat application.
