COST-EFFECTIVE SOLUTIONS O-rings are one of the oldest and most widely used styles of seal geometries in the Aerospace industry today. This uncomplicated design provides a suitable, cost-effective solution to a variety of sealing applications. O-rings can be used either as a seal itself or as the energizing element in a variety of PTFE, cap-type seals. Greene Tweed's extensive seal experience and superior quality is reflected in our ability to manufacture O-rings made from high- performance, elastomeric materials. A variety of expressly formulated compounds are available to meet our customer's specific application FEATURES & BENEFITS Simplistic, cost-effective geometry Wide range of sizes available for AS4716 and MIL-G-5514 gland configurations • Fuel systems • Control valves • Utility actuators • Energizers for PTFE cap seals This series of O-rings is designed to meet the dimensional requirements for several of the industry's O-ring standards such 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.
