Rubber Packing Seals: Custom NBR, FKM, EPDM Solutions

Xingtai Longcheng Sealing Co., Ltd. produces a niche product, rubber packing seals, without which many industries could not function. Our company philosophy pledges the best quality packing seals. Our in-house developed rubber compounds combined with our Research and Development team's attention to rubber mixing ensures our seals will meet the best the rubber sealing industry has to offer with a compromise in performance limitations, temperature resistance, chemical stability, or flexibility. Long before the rubber compounds are tested, our team members underwent meticulous training in the most current, state of the art molding techniques. Their performances are regulated and monitored against the highest of the international standards. We have over ten thousand molds developed for customization. Once our seals are molded we do not compromise during our testing. Our quality assurance team's tests apply the highest demands for every single possible application: machinery, mining, agriculture, home appliances, automobiles, and railways. If our tests show a seal is subpar, we will redesign a seal before sending it to a client. Our standards are upheld with our commitment to quality. Our customization options are a reflection of our dedication. Dimensions and rubber types are flexible to our client's needs. Their needs dictate the color as well. Our reliability has expanded our business and has strengthened our reputation. Over 300 companies, and counting, have trusted us. Close to 150 countries have manufacturered our seals. Our quality and excellence have been recognized.
