263 Series<\/p>\r\n <\/div>\r\n

\r\n
\r\n
\r\n

The 263 is one of the most robust 5-piece piston seals available on the market. It consists of a profiled energizer, a PTFE-filled seal element, two active anti-extrusion backup rings and an elastomeric quad ring. It is designed for double-acting cylinders in heavy-duty applications subject to severe pressure spikes coupled with high running clearance. It zero drift performance due to the elastomeric seal ring, which also makes it ideally suited for gas sealing applications.<\/h3>\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n<\/section>\r\n

The 263 series piston seal features custom blended PTFE-filled compounds that provide ultra-low friction and high-speed performance and minimal wear. The standard compounds are PTFE-filled with bronze filler or PTFE-fille with glass-moly. The 263 series features a robust elastomeric energizer with backup rings in a high strength thermoplastic. The temperature range of the seal can be increased by selecting an FPM energizer in place of the standard NBR energizer.<\/p>\n <\/div>\r\n \r\n \r\n \r\n
