The Highest Quality Vulcanized O-Rings in the Industry
We Stock Hundreds of Cord Varieties for Every Application
Vulcanized o-rings are made from cut cord stock with both ends fused together, and are a great option for static sealing applications. We apply a liquid form of the uncured material to the ends and join them together in a heated mold. The heat and pressure cause the liquid material to cure and form a chemical bond between the ends with cross-links between the long-chain molecules. We inspect 100% of the vulcanized o-rings we produce before they leave our shop to make sure the material is free from defect and the joint is clean and strong. For nonstandard sizes in dynamic applications, we can produce custom-molded o-rings.
What We Offer
Global O-Ring and Seal carries nearly 500 cord varieties with more than 1 million feet of cord in stock – in combinations of the profile, material, cross-section, durometer, and color. We can produce vulcanized o-rings in round, square, X profiles, and custom profiles.
Standard materials we vulcanize include Buna (Nitrile), Viton® (FKM), Aflas, Neoprene, EPDM, Neo/EPDM Blend, Silicone, and Fluorosilicone.
The cord can be Butt Cut or Bevel Cut. Butt Cut is a straight 90º up-down cut. Bevel Cut, also known as skive cut, slices at a 45º angle, giving more opportunity for surface area contact and added tensile strength. To see more details regarding our cord tolerances, click here.
Our Vulcanized O-Ring Calculator automatically calculates the necessary dimensions of a vulcanized o-ring based on cross-section and any other known dimensions such as ID, OD, MD, and cut length.

连续的提高
我们继续投资，力争成为最好的。为此，我们增加了自动切割机和电脑控制硫化机等设备，以进一步提高我们的硫化能力和产量。
无论您的电源线是自动还是手动切断，您都可以放心，我们满足或超过行业公差标准。
质量检测
每个 O 形圈在离开我们的硫化车间之前都经过单独检查，确保其安装和表面光洁度。我们的拉力测试仪对硫化产品进行常规取样，直至失效。记录并分析拉伸强度、断裂力和极限伸长率。
在定期执行这些测试时，Global O-Ring and Seal 可以审核和改进硫化过程，并继续提供尽可能最高质量的 O 形圈。
检查程序
使用正确的粘合剂、在正确的温度下硫化压机/模具以及固化时间可以提供硫化接头的机会，使其超出规定的规格。更重要的是，工艺对于确保最终产品的最高质量同样重要。 Global O 型圈和密封件对我们制造的每个环进行 100% 检验，以确保符合工艺标准，并且您收到的产品将按承诺工作。下面是对每个硫化环采取的检查步骤。
未经检验的硫化环不出厂。每个环都经过扭转和拉力训练。使用环后，在放大镜下对其进行彻底检查，以确认没有产生裂纹或针孔。检测过程包括稍微弯曲环，同时检查是否有毛刺、针孔和任何其他不合格之处。如下图所示，不建议过度弯曲环，因为它在应用中并不意味着弯曲。弯曲环会产生悬臂效应，放大环外边缘上的张力。这会导致关节损伤。
