Industrial O-Ring Cord & Gasketing for Custom Sealing Applic
Gasketing
Industrial O-ring cord, also known as gasketing cord or O-ring cord stock, is one of the most versatile sealing solutions available today. While commonly used in filter presses, this material is widely applied across vacuum systems, tank sealing, industrial equipment, and maintenance operations where standard molded O-rings are not practical.
At FilterPressGasket.com, we supply high-quality O-ring cord in multiple materials and diameters, ready to be cut to length for your exact application.
🔧 What Is O-Ring Cord?
O-ring cord is a continuous length of elastomeric sealing material with a round cross-section. It can be cut and joined to form custom O-rings of virtually any diameter.
This makes it ideal for:
- Large diameter seals
- Custom equipment
- Emergency repairs
- Hard-to-source gasket sizes
Common Applications for O-Ring Cord
O-ring cord is widely used as gasket material in filter press plates, sealing each chamber to prevent leaks and maintain pressure during operation.
👉 Used in:
- JWI filter presses
- Evoqua / Siemens J-Press
- US Filter presses
- Met-Chem filter presses
Vacuum Chamber Seals
O-ring cord is an excellent solution for large diameter vacuum seals, especially when standard molded O-rings are unavailable.
Applications include:
- Vacuum chambers
- Lab vacuum systems
- Composite curing systems
- Degassing tanks
Tank Lid & Manway Seals
Used in:
- Wastewater treatment tanks
