Cord Stock

Cord Stock Profiles

Global O-Ring and Seal offers cord stock in several profiles to accommodate a range of applications. Each profile is designed to meet specific performance requirements.

• O-Ring Cord Stock: The most common and versatile profile, round cord is ideal for fabricating o-rings of non-standard sizes and is widely used in static sealing applications.
• Backup Ring Cord Stock: Shaped to replicate standard backup ring geometry, this profile enhances extrusion resistance in high-pressure environments when used with o-rings.
• X-Ring Cord Stock: Featuring a four-lobed design, x-ring cord offers multiple sealing surfaces, reducing friction compared to round profiles.
• Square Cord Stock: Square cord provides a larger sealing surface and is commonly found in static applications where added stability and extrusion resistance are beneficial.
• Rectangular Cord Stock: Rectangular cord provides a broader sealing surface where groove dimensions require a non-square share.
