The 1860 wiper series includes notched wiper rings specifically designed for reciprocating or linear applications requiring a clean and debris-free shaft. These wiper rings are compatible with any -25 series rings and can be combined in various configurations to create replacement control-valve packing sets for a wide range of valve manufacturers’ products.
The standard configuration consists of a molded PTFE set, comprising three “V”-rings, one “M”-ring, one “F”-ring, and a wiper ring, precision-engineered for optimal performance in commonly used control valves. The higher-profile design features thinner “legs” that enable sealing at lower operating pressures, reducing the required compression of the packing set.
This design configuration makes our V-Ring packings suitable for most applications. Additionally, component parts are available separately for custom configurations, allowing for tailored solutions. Wiper rings are frequently integrated with packing sets, typically used with nominal fractional sizes. Custom sizes are available upon request, ensuring adaptability to specific application requirements.
Heights are infinitely adjustable per customer request, without any need for tooling charges.
Pressure Ranges and Recommended Number of Rings per Packing Set*
| Pressure Range | Female Rings | V-Ring Packing Sets | Male Rings |
