Description
Product Advantages
The Double Delta  is a rubber-energized plastic sliding face seal.  
This seal is designed to extend and improve the operating parameters of O-rings while being installable in existing O-ring grooves.  
The Double Delta combines the elasticity and responsiveness of an O-ring with the friction and wear characteristics required for dynamic applications.  The dual-acting performance of the seal stems from its symmetrical cross-section, enabling it to handle pressure from both directions, as illustrated in Figure 130.  
The radial compression of the O-ring provides initial contact pressure, which converts into additional contact pressure as system pressure increases. Consequently, the seal's contact pressure automatically adjusts to ensure effective sealing under all operating conditions.
- Compact groove dimensions, easy installation  
- Low friction, no "stick-slip"  
- Wear-resistant and extrusion-resistant  
- Piston seal diameter range: 5~999.9 mm  
- Standard cross-sections comply with AS 568A specifications and key metric O-rings; other cross-sections can be customized upon request  
- Also suitable for groove dimensions per ISO 6194 and AS 4716 standards

Double Delta with oil drain grooves
The standard Double Delta seal is supplied without radial pressure relief grooves, as the seal's thin radial cross-section responds well to pressure variations.  
For grooves with diameters above 8 mm, optional pressure relief grooves on both sides are available, ensuring the seal directly applies pressure to the cylinder barrel under all operating conditions.
