Lipped seal 4150 series

O-ringelastomer

The 4150 series of O-rings has larger cross-sections for improved static sealing. Historically, O-rings designed for static applications but used in dynamic-type glands such as MIL-G-5514 or AS4716 have experienced sealing leakage challenges under certain circumstances. To help combat this issue, new static gland standards such as AS5857 feature decreased packing space. This allows standard O-rings to exhibit higher levels of squeeze and helps to reduce sealing problems. Alternatively, the larger cross-sections of our 4150 O-rings are specifically designed to impose optimal levels of high squeeze in the existing dynamic gland standards of AS4716 and MIL-G-5514.
