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.

Hallite's OptiSeal VSC is a spring-loaded internal pressure seal. It features a U-shaped seal jacket that incorporates a V-shaped corrosion-resistant metal spring. When there is no load or at low pressure, it provides the necessary spring load to the seal lip, creating the appropriate contact surface pressure. As the operating pressure increases, it acts on the sealing performance at high pressure by receiving the system pressure in the U-shaped area. The standard material is a high-performance seal jacket material based on PTFE. It exhibits low friction against almost all mating surfaces, thereby eliminating stick-slip phenomena. **Features** - Easy assembly with a simple groove design - Ideal for all flange applications - Excellent chemical resistance and a wide range of temperature and pressure resistance - Low friction at low rotational speeds Hallite is a subsidiary of the Michelin Group.

Hallite's OptiSeal VSE is a spring-loaded external pressure seal. It features a U-shaped seal jacket that incorporates a V-shaped corrosion-resistant metal spring. 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. It exhibits low friction against almost all mating surfaces, thereby eliminating stick-slip phenomena. **Features** - Easy assembly with a simple groove design - Ideal for all flange applications - Excellent chemical resistance and a wide range of temperature and pressure resistance - Low friction at low rotational speeds Hallite is a group company of Michelin.

Hallite's OptiSeal VSR is a spring-loaded single-acting rod seal. It features a U-shaped seal jacket that incorporates a V-shaped corrosion-resistant metal spring. 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 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.
