315 Series: Dirt Wiper – Double Acting – OR Energizer
The 315 Series Heavy-Duty, Double-Acting wiper is one of the most popular heavy-duty wipers.
315 Series
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.

Material Ranges
The 315 Series wiper consists of a custom-blended PTFE-filled compound 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.
