Heavy-Duty, Double-Acting Wiper
Series 315: Heavy-Duty, Double-Acting Wiper
The 315 Series Heavy-Duty, Double-Acting wiper is one of the most popular heavy-duty wipers. It includes a reinforced PTFE-filled scraper ring and one energizing O-ring. 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-ring energizes the two wiper lips. In most applications, a pressure relief port between the wiper and the rod seal is recommended.

Applications
The 315 Series Heavy-Duty, Double-Acting Wiper prevents contamination ingress in harsh environments, while maintaining low friction.
Typical Applications
- Forging presses
- Extrusion presses
- Stamping presses
- Steel and aluminum mills
- Injection molding machines
- Cold and hot strip mills
The 315 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.
