The Hallite OptiSeal JBR is a spring-loaded type seal for single pressure applications, compatible with the JIS B2401 P-type groove. It features a U-shaped seal jacket with a V-shaped corrosion-resistant metal spring integrated into its structure. When there is no load or at low pressure, the spring provides the necessary load to the seal lip, creating the appropriate contact surface pressure. As the operating pressure increases, the system pressure acts on the U-shaped area, influencing the sealing performance at high pressure. The standard material is a high-performance seal jacket made from PTFE (fluoropolymer). It demonstrates low friction against almost all mating surfaces, thereby eliminating stick-slip phenomena. **Features** - Excellent chemical resistance, adaptable to various applications - Low friction eliminates stick-slip phenomena - Compatible with JIS B2401 P-type grooves - Excellent wear resistance and long service life - Suitable for a wide temperature range - Superior dynamic and static sealing characteristics of tandem lips Hallite is a group company of Michelin.

The standard material is a high-performance seal jacket made of PTFE. It exhibits low friction against almost all mating surfaces, thereby eliminating stick-slip phenomena. **Features** - Excellent chemical resistance, adaptable to various applications - Low friction eliminates stick-slip phenomena - Superior wear resistance for long service life - Suitable for a wide temperature range - Excellent dynamic and static sealing characteristics of tandem lips Hallite is a group company of Michelin.

Hallite's OptiSeal VSP is a spring-loaded single-acting piston seal. It features a U-shaped seal jacket with a V-shaped corrosion-resistant metal spring integrated into its structure. When there is no load or under low pressure, it provides the necessary spring load to the seal lip, creating appropriate contact surface pressure. As the operating pressure increases, it acts on the sealing performance at high pressure by receiving system pressure in the U-shaped area. The standard material is a high-performance seal jacket material based on PTFE. It demonstrates low friction against almost all counterpart surfaces, thereby eliminating the stick-slip phenomenon. 【Features】 ■ Excellent chemical resistance, adaptable to various applications ■ Low friction eliminates stick-slip phenomenon ■ Excellent wear resistance and long lifespan ■ Suitable for a wide temperature range ■ Outstanding dynamic and static sealing characteristics of tandem lips Hallite is a group company of Michelin.

Hallite's OptiSeal VSF rotary seal is a PTFE (fluoropolymer) seal equipped with a corrosion-resistant metal spring. The seal can be securely fixed to the housing by sandwiching the flange of the seal between the housing. This prevents the seal from rotating with the shaft and alleviates the clamping effect on the shaft caused by system pressure, resulting in reduced torque. Additionally, since the seal is fixed to the housing, it is also ideal for applications that require high-frequency strokes in reciprocating motion. 【Features】 - Excellent chemical resistance, suitable for various applications - Low friction eliminates stick-slip phenomena - Design prevents rotation with the shaft - Accommodates a wide temperature range - Tandem lip design provides excellent dynamic and static sealing characteristics Hallite is a group company of Michelin. M.O. Tech Co., Ltd., a specialized trading company for sealing systems, is the only officially authorized distributor of Hallite in Japan.

Hallite's OptiSeal VSS rotary seal is a seal that incorporates a corrosion-resistant metal spring and is made of fluoropolymer. By integrating an O-ring into the outer circumference of the seal, it generates high friction between the seal and the housing, improving both anti-rotation with the shaft and sealing performance. 【Features】 ■ Anti-rotation design with the shaft ■ Low friction for long service life ■ Excellent dynamic and static sealing performance with tandem lip design ■ Can be used as a rotary seal, static seal, or reciprocating motion seal ■ Ideal for low temperature and low pressure applications ■ Excellent chemical resistance and high-temperature resistance, suitable for various applications ■ Other O-ring materials can be used if exceeding temperature ranges ■ Stable design and reliability Hallite is a group company of Michelin. M.O. Tech Co., Ltd., a specialized trading company for sealing systems, is the only officially certified distributor of Hallite in Japan.

OptiSeal JBR has excellent chemical resistance and uses PTFE materials or high-performance resins, making it highly compatible with various chemical substances and capable of adapting to a wide range of environments. 【Usage Scenarios】 - Chemical manufacturing equipment - Lubrication-free environments - Extremely low to high temperature ranges 【Benefits of Implementation】 - Reduced risk of foreign matter contamination due to high sealing performance - Suppression of product impact due to chemical resistance - Cost reduction through extended lifespan

In the semiconductor industry, high cleanliness is required to maintain the quality of the manufacturing process. Particularly in areas that come into contact with chemicals and gases, the material of the seals is crucial, and it is necessary to prevent contamination. OptiSeal JBR uses PTFE, which has excellent chemical resistance, as the jacket material, demonstrating high sealing performance even in harsh environments. This contributes to improving the reliability of semiconductor manufacturing equipment. 【Usage Scenarios】 - Chemical supply lines - Gas supply lines - Equipment in clean rooms 【Benefits of Implementation】 - Reduced risk of contamination - Improved equipment operating rates - Stabilization of product quality

"OptiSeal" is a sealing system that withstands harsh applications such as liquid nitrogen at -196°C, featuring chemical resistance and suitability for high and low temperature uses. It uses PTFE and high-performance resins for the seal material, incorporating springs made of stainless steel or Hastelloy. The built-in spring applies surface pressure to the seal lip to maintain sealing performance during no-load or low-pressure conditions. During pressurization, the U-shaped seal housing receives pressure to ensure the necessary surface pressure. It allows for smooth operation even in a non-lubricated state. 【Features】 ■ Uses PTFE and high-performance resins for the seal material ■ Incorporates springs made of stainless steel or Hastelloy ■ Allows for smooth operation even in a non-lubricated state ■ Suitable for not only fixed applications but also reciprocating, oscillating, and rotating movements ■ Custom sizes beyond those listed in the catalog are also available *For more details, please download the PDF or feel free to contact us.
