SummaryThe supplier manufactures industrial sealing products, including spiral wound gaskets, PTFE tape, and PTFE gaskets, from a 4,500 m² facility with three production lines. It offers extensive customization, 3D design, ODM, and OEM services, and reports new products within the past year.

The supplier has inventory capability and valid contracts with affiliated subcontractors, but no overseas warehouse, showroom, agents, branches, or overseas service locations. Export activity is reported, with 31%–40% of sales from exports and four years of export experience. Customer evidence includes a 50%–80% repeat-buyer preference, but no Fortune 500...
