For over fifty years, Seals Eastern has manufactured the highest quality o-rings, gaskets, and custom seals for industry. We specialize in seals capable of mission critical, long term service in demanding applications. We understand that a successful seal must embody a proper engineering design, an appropriate sealing material, and a reliable, repeatable, manufacturing process.

Simply basing your rubber seal on the correct polymer is
not enough. Naturally, a polymer suitable for the interplay of temperature, pressure, and environmental media is necessary for an effective seal. However, to achieve long-term service, the right polymer must be compounded with proper fillers, curatives, and chemical agents. Only then, with proper manufacture, can a seal withstand high temperature, high pressure, and chemical degradation to deliver long-term,
leak-free service.
