AI-Powered supplier vetting

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. Quality-related evidence includes CE certification, ISO 9001:2015 certification, quality assurance, and documented corrective and preventive action procedures. However, complaint handling lacks written records, supplier approval documentation is incomplete, and the factory does not continuously reconcile production quantities or maintain standard outsourcing procedures. 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...

Product Q&A

Q:What is the function of the inner ring in this gasket?

The inner ring prevents gasket implosion during installation, safeguards the sealing element, fills the void between flanges to prevent erosion, and minimizes failure risks.

Q:What materials are available for the inner and outer rings?

Inner rings are crafted from the same alloy as the winding (e.g., 304, 316L, Monel400, Inconel625). Outer rings are typically carbon steel (painted or zinc-plated) or alloys for higher temperatures.

Q:What standards does this spiral wound gasket comply with?

The gasket complies with DIN 2699 (German) and ASME B16.20 standards, which mandate inner rings for specific filler types and general safety.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 2 units.

Q:Does the supplier offer OEM or ODM services?

Yes, the supplier offers both OEM and ODM services, including full, minor, and flexible customization from samples or designs.
