Infinite Possibilities
Large Seamless O-Rings (LSO) eliminates the high tooling costs of molded and the weak connections of vulcanized.
Seamless is an advanced continuous molding process using unique tooling and a secondary process that yield high quality
O-Rings.
Large Seamless O-Rings are made using a variety of high quality elastomers, broad range of cross sections, infinite diameters, superior service and eliminate the high tooling costs of molded and the weak connections of vulcanized all at a competitive price.
Why Seamless
O-Rings were invented in 1936 and the two main methods to manufacture O-Rings has remain the same since the beginning, compression molded and vulcanized.
These methods work, but for large O-Rings they do have their short comings.
Compression molding requires very expensive tooling, long lead times, quality issues and high costs.
Vulcanized (Spliced) O-Rings the connection are weak compared to the rest of the part, limited standard cross sections and materials.
LSO eliminates all of these issues and also offers you infinite possibilities.

Encapsulated O-Ring seals are almost universally used in harsh environments. These seals are the ideal solution in the face of sealing problems given their chemical resistance, elastic properties, and low friction.
Applications:
Pumps and valves, marine motors, mechanical locking, filters, pneumatic motors, heat exchangers, autoclaves, pipelines, and compressors, among others.
Common Profiles
- Solid most common
- Hollow core offers more flexibility and less clamping force.
- Round (O-Ring)
- Square and Rectangle profiles design to be a gasket.
- Rectangular profiles designed to be a universal fit, Camlock hose coupling seal.

Spliced / Vulcanized O-rings
Spliced and vulcanized O-rings are made from extruded cord stock that has been cut and bonded together, as opposed to molded O-rings; those that have been compression or injection molded as one piece.
- Good choice for static sealing applications.
- Made from a range of elastomers
O-Ring cord is cut to length, a bonding agent is applied to the ends and joined together in a mold at a high temperature.
Cut Type
- Butt Cut Standard Method
- Bevel Cut (Improves joint strength)
Cord can be made to almost any shape and the ends can be spliced together.

Square Cut Rings
Square Rings are available in a variety of rubber and plastic materials. In most static applications, a Square Ring will serve as a direct replacement for an O-ring and generally will perform a high-pressure sealing function as well as or better than an O-ring.
