Z-Seal ring Description
A Z-ring seal (also called a Z-ring seal) is a common sealing element typically used in static sealing applications. Its cross-sectional shape is "Z" shaped. Z-ring seals are usually made of elastic materials (such as rubber or polyurethane).
The various Z-seal ring configurations are designed to accommodate standard groove dimensions with normal manufacturing tolerances. Z-seals fit into standard deep-loaded U-cup glands. For groove dimensions please reference the loaded U-cup section.
Z-seals ring are designed with a greater tolerance to side loading and additional compensation for axial run-out. The double lip design provides greater resistance to compression set and extended life for the elastomeric seal element. Z-seals are ideally suited for dynamic rod applications as the depth of the design provides an increase in stability in higher-pressure applications.

Z-Seals standard part numbers are based on a urethane base material and a nitrile loader. Other popular materials include a Fluorotrel® base, Viton™ loader, and low-temperature loader.

Features
- Sealing performance: Z-ring seals can provide better sealing performance and can effectively prevent liquid or gas leakage.
- Elastic deformation: Due to the characteristics of its elastic material, the Z-ring seal can return to its original shape when subjected to external pressure or deformation, ensuring the sealing effect.
- Corrosion resistance: It can have good corrosion resistance and is suitable for sealing various chemical media.
- Easy installation: The installation of Z-ring seals is relatively simple, and sealing is usually achieved by placing it in the sealing groove or sealing surface. For applications exposed to severe shock loads or large clearance gaps, the modular "Delta" back-up ring provides the most economical way to close diametrical clearances with additional resistance to extrusion. Positively actuated to control friction, the split Delta design allows ease of installation and retains original seal height and groove depth.
