Standard Methods for Retaining Metal Seals
Many customers wish to retain metal seals for particular use cases, like vertical or horizontal axis installations. To help you decide which is best, we have some traditional standard methods. The first method is clips and screws, which are used with either the very large (200+ inch diameter) O-FLEX™ or HELICOFLEX® RPV seals.
This method works best with large applications because there is more space to place the clips and screws. With the affordability of these parts, this is one of the lower-cost methods. For our second method, the HN208 and HN203 seals are similar in customization capabilities and most functionalities.
However, the HN203 is not traditionally used in a compression manner, while the HN208 is used for metal-to-metal contact. Finally, the HND290 method has extended leg liners to add centering features and retention holds to affix the design to your hardware. This allows for even more customizability, but also, because of this feature, there is more demand for tooling costs, which makes this method the most expensive of the three. So, what’s the biggest takeaway? If retention is important, we will need more space to make it easy for your operators installing the seals into your system.
