joint o ring

As usual, a joint o ring is made by o ring cord.The molding technology for joint O-rings allows us to promptly manufacture an O-ring with a size that meets the requirements.

Previously, if there is no die available, an O-ring was made by bonding extruded rubber strings with an adhesive, etc. In this way, however, bonded rubber strings had problems in strength, resistance to heat, oil, and chemicals, sealing performance, etc. Joint O-rings are molded using press vulcanization, a conventional molding method for rubber. No adhesive is used. Therefore, a joint O-ring has as good a performance as any ordinary molded product.
