Product Specifications/Summary

SUNFLON® U-seal A seal combining a PTFE jacket that features a U-shaped cross-section with a U-shaped stainless steel spring.
It is not affected by an array of chemicals and organic solvent, etc. that create conditions in which rubber seals cannot be used, and is applicable throughout a wide temperature range.
SUNFLON® RL seal A rotary shaft seal using PTFE seal element. It can be used in conditions that are more severe than rubber oil seals are capable of tolerating. It has exceptional wear resistance and can be used even without lubrication.
Metal seal It exhibits high-level sealing properties even in ultra-high vacuum, extremely low temperatures, and in severe environments such as high temperature or high pressure environments.
We also have low tightening force types.
Pneumatic cylinder seals As they fit in the grooves of the pneumatic cylinder seals such as JISB2401-2, JEPS2003, and JEPS2004B, we can provide seals with excellent wear resistance, low friction, and dust resistance.
Solenoid valve seal We can provide customized products that meet customer needs, including seal spool packings, check seals, and poppets.
Fastener seal A fixed seal for bolts, etc. that combines rubber with a metal retainer. We also have high-pressure types.
Seal-ring A floating seal for rotary and reciprocating equipment such as seal-ring oil pumps and compressors. It uses PTFE or engineering plastic depending on the use environment.
We also develop custom products to meet customer requirements.
O rings We contribute to the improvement of product performance and provide solutions to customer problems using an array of materials that achieve the operating temperatures necessary for O rings and sealing fluid, etc.
