O-Ring Cord

O-Ring Cord – Cut to Length & Ready to Seal

Seal With Selo O-Ring Cord is the perfect solution when you need custom-sized seals fast.

More materials — such as Viton® (FKM), EPDM, and Silicone — will be added soon. If there’s a size or material you need that isn’t listed yet, get in touch and we’ll source it for you.
