273 Series: Piston Seal – Step Cut – HD Energizer
The 273 Series Heavy-Duty Step-Cut Piston Seal is an ideal upgrade from traditional cast iron piston rings..
271 Series
The 271 Accumulator Piston Series is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.
Installation Drawing
Material Ranges
System Seals™ custom blended PTFE-filled compounds provide ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFE with Bronze filler, or PTFE filled with Glass-Moly. The temperature range of the seal can be increased by selecting an FPM energizer in place of the standard NBR energizer.
