Large-diameter joint-type O-ring

Stable finishing, appearance, and dimensional accuracy! Molding is carried out using various equipment dedicated to joint molding.

We would like to introduce our "Large Diameter Joint Type O-Ring." Traditionally, O-rings without molds were connected using adhesive to extruded rubber cords, but this method had issues with the strength, heat resistance, oil resistance, chemical resistance, and sealing performance of the adhesive parts. Our product is molded using press vulcanization, which is the original molding method for rubber. Since no adhesives are used, it has the same performance as standard molded products. 【Features】 ■ Molded by press vulcanization ■ No adhesives used ■ Has the same performance as standard molded products ■ Does not require molds for single items or small lots ■ Large diameter O-rings can be manufactured at low cost and with short lead times *For more details, please refer to the PDF document or feel free to contact us.
