Self Retaining Seas for Pneumatic Applications
Self retaining seals from Parker are advanced sealing solutions designed for pneumatic cylinders and dynamic applications where reliable sealing, wiping and secure positioning are essential. These innovative profiles combine multiple functions into a single component, reducing installation complexity and improving performance.
At Ashton Seals, we supply high-quality self retaining seal and wiper profiles engineered for long service life, low friction operation and consistent sealing performance across a wide range of industrial applications.
What are self retaining sealing
Self retaining seals are specially designed pneumatic rod seal and wiper systems that integrate three core functions:
Sealing
Wiping (contamination exclusion)
Fixing (retention within the housing)
This multifunctional design eliminates the need for additional components such as circlips or retainers, simplifying assembly and reducing potential failure points.
Key features and benefits
Self retaining seals offer several performance advantages:
Three-in-one functionality – seal, wiper and retainer combined
Reduced installation time – easy fitting into open housings
Improved reliability – fewer components means fewer failure risks
Low friction performance – optimised lip geometry supports smooth operation
Long service life – wear-resistant materials and balanced design
Corrosion-free retention – no metal circlips required
These features make them particularly suitable for demanding pneumatic and automation systems.
