"O-Seal" is an O-ring type sealing material that boasts excellent chemical and solvent resistance, as well as heat and cold resistance. It features a core material made of silicone rubber or fluororubber, coated with elastic fluororesins such as FEP or PFA, which also prevents leaching. Available in a wide range of sizes from 1.5 to 25.4 mm in diameter, it can be customized for both wire diameter and inner diameter. 【Features】 ■ Difficult to stick ■ Compliant with FDA standards ■ Compatible with standard O-ring sizes ■ Large sizes, such as 5 m inner diameter, can also be produced ■ A hollow core type with reduced clamping force is available *For more details, please refer to the materials available for download in PDF format. Feel free to contact us with any inquiries.

Stainless steel springs with ultra-low temperature high-performance fluoropolymer (PTFE) coated O-rings are available in a wide range of sizes, from a wire diameter of 1.6mm to 25.4mm, including products equivalent to JIS and AN standards, as well as special sizes. O-seals are made by bonding and fusing materials, allowing for the production of large diameter seals, such as those with a diameter of 5m. The manufacturer, Chrysler Encapsulated Seals in the United States, has a proven track record with these seals, and their performance and quality are well-regarded. 【Features】 ■ Excellent chemical and solvent resistance, preventing contamination of fluids (products) ■ Excellent heat and cold resistance 　　(FEP: -250℃ to +260℃, PFA: -250℃ to +260℃) ■ Compatible with conventional O-ring sizes, allowing for easy modifications For more details, please contact us or download the catalog. *This catalog is in English.

The multi-purpose sealing material, Dynalip Seal, is a lip seal made entirely of PTFE, developed based on a new design philosophy specifically for rotation. Conventional oil seals with rubber or PTFE lip seals are housed in metal casings, making them unsuitable for small-batch, varied production. However, the Dynalip Seal is made through machining from PTFE material, allowing for any shape or dimension, making it suitable for small-batch, varied sealing needs. Additionally, it is easy to attach and detach from the housing, has good handling properties, and does not deform or damage the housing. 【Features】 ■ Suitable for high-speed rotation → Can achieve peripheral speeds of up to 30 m/s when lubricated ■ Can withstand pressures up to 0.9 MPa ■ Low friction ■ Usable from -54℃ to +180℃ ■ Resistant to various fluids → The corrosion-resistant PTFE is not affected by most chemicals and can also seal in dry running (gas seals), abrasive fluids, and powders. ■ Does not damage the sealing bore → The fixing material of the Dynalip Seal (bore side) is in contact with an O-ring, ensuring that repeated replacements do not damage the bore. *For more details, please download the catalog.
