Large Diameter O-Ring
Large equipment can sometimes require elastomeric seals that exceed the size limitations of conventional compression molding presses. Our patented Extensis® spliced and vulcanized process or our continuously vulcanized horseshoe molding process offer unique solutions for various application needs. Greene Tweed has molded o-rings as large as 98 inches (2,489 mm) but there is no maximum diameter limit.
Features & Benefits
For high-pressure, vacuum, dynamic, or otherwise extreme application conditions, the horseshoe molding process yields the highest performance and is consistent with that of typical compression molded o-rings. With this method, uncured extrudate is continuously vulcanized along a horseshoe-shaped mold cavity. This process most closely aligns with traditional compression molding processes and produces a truly homogenous joint. This method is typically used for critical equipment where asset integrity is paramount, such as compressors used in oil & gas and power generation industries. Our rapid gas decompression (RGD) resistant compound Fusion™ 938 is a popular choice for these applications.
