حلقات O-Ring فيتون FKM 0.139 بوصة CS × 1.109 بوصة ID | AS568-216 | داش 216 | قابلة للكشف المعدني | صلابة 75 (14 / عبوة)

These are the first o-rings I've bought that actually set off a metal detector, which is a huge relief for our food line inspections. The Viton material handles our steam cycles up to 400°F without any swelling or cracking, and the 75 durometer feels firm but seats nicely in the groove.

The metal-detectable feature is a real time-saver during maintenance—no more worrying about lost fragments in food-grade lines. These fit perfectly on the standard 1-inch port I was repairing, and the 75-durometer stiffness feels just right for a leak-free seal.

These o-rings handled the high-temp steam in my autoclave without any swelling or hardening after a week of cycles. The metal-detectable feature is a nice bonus for food processing equipment.
