Lathe-cut products are a logical and economical alternative to the standard O-Ring in most static applications.

    These lathe-cut seals can be custom made to your application without the tooling costs of molded parts and are available in a wide variety of compounds.  We can also provide you with special part processing and packaging to meet your specific needs.

    A lathe-cut seal is manufactured from a cylindrical tube of rubber which is compounded to match your required specifications.  Through a curing process and stone grinding on the lathe, the inside diameter (ID) and outside diameter (OD) are determined (see Figure 1).   The desired thickness is achieved on the lathe by a knife-cutting process.  It's the knife-cutting process that defines each seal's unique cross-section which determines how they are classified.   These classifications include: Square, Rectangle, Chamfered, Angular, V-groove, Tube, Gasket Cut and Cylindrical Cut, of which we offer a wide variety.  (see Figure 2)

    For custom lathe-cut applications, a blueprint with cross-sections, tolerances, dimensions and compound specifications is required.   To serve you better, we have engineers and chemists on staff who would like to assist you in your design process.

Square and Rectangular Cut- can be used as an economical alternative to the "O-ring" in hydraulic and pneumatic sealing applications.	Angular Cut- may be used as an economical dynamic lip seal with the appropriate groove design.	Cylindrical Cut- seals function in many mechanical applications including: drive belts, covers and sleeves as well as regular seal devices.
Chamfered Cross-section Cut- are used in dynamic applications, where there is a need to reduce surface contact area and the resulting friction.	Gasket Cut- seals are used as face seals, flapper check valves and economical wiper - scraper wings.	V-Groove Cut- seals are designed for applications in which it is necessary to reduce contact area without changing the overall size of the seal.
