The 314 Series Heavy-Duty, Double-Acting wiper is one of the most popular mill-duty wipers in the steel industry. It includes a reinforced PTFE-filled scraper ring and two energizing O-rings. The design incorporates a wiping lip to prevent contamination from entering the cylinder and an inner sealing lip to remove any oil film from the rod as it cycles. The O-rings individually energize the two wiper lips. In most applications, a pressure relief port between the wiper and the rod seal is recommended.
Protects the hydraulic cylinder internals
Works in short stroke applications
Works in high-temperature environments
The 314 Series Heavy-Duty Double-Acting Wiper prevents contamination ingress in harsh environments, while maintaining low friction.
The 314 Series Heavy-Duty Double-Acting wiper consists of a custom-blended PTFE that provides ultra-low friction and high-speed performance with minimal wear. The standard compound is PTFE with Bronze filler. The temperature range of the wiper can be increased by selecting an FPM energizer in place of the standard NBR energizer.
