Rubber Gaskets and O-Rings

Rubber gaskets and O-rings from Hebei Jingzhun serve both static and dynamic sealing duties where resistance to media is critical. NBR is used for oil and fuel contact, silicone for wide temperature excursions and food-contact or electrical insulation requirements, and EPDM for weather-exposed and outdoor service. Typical installations are flange sealing and hydraulic systems. Parts are moulded to drawing or sample, in standard as well as custom sizes, using the company's mixing, compression molding, injection and vulcanization lines. Under the ISO 9001 system each batch undergoes incoming material testing, in-process quality control, first-article and patrol inspection and final tests covering dimensions, hardness and tensile strength, with full batch traceability back to raw materials and production records, so no defective part leaves the factory.
