Kaxite Seals supports distributors, OEM brands and EPC contractors worldwide. Below are typical cooperation cases and the inspection documents we provide for every bulk gasket order.
A German EPC contractor ordered 12,000 pcs of SS316L/graphite spiral wound gaskets to ASME B16.20. Batch MTRs and dimensional reports were provided for each shipment.
A UAE industrial distributor placed recurring monthly orders of virgin PTFE gaskets with FDA-compliant material. Neutral packaging and private labeling were used.
A US OEM brand ordered custom non-asbestos gaskets with private-label packaging. Samples were approved within 7 days and mass production started immediately after.

Q: What is the MOQ for wholesale gaskets from Kaxite Seals?
A: Our standard MOQ is 50 pieces per gasket type for wholesale orders. For custom and OEM gaskets, MOQ may vary depending on material, dimensions and packaging requirements. We also offer free samples for quality evaluation before bulk purchase.
Q: How long is the lead time for bulk gasket orders?
A: Standard lead time is 7-15 working days for most gasket products. Custom and OEM orders may require 15-25 working days depending on specifications and order quantity. Rush orders can be accommodated upon request. We ship worldwide via sea, air and express couriers.
Q: Can I get custom gaskets with my own dimensions and branding?
A: Yes. Kaxite Seals provides OEM and ODM services, including custom dimensions, materials, logos, labels and packaging. Send your drawings or samples and our engineers will confirm feasibility, MOQ and lead time.
Q: What payment terms do you accept for bulk gasket orders?
A: We accept T/T, L/C at sight, PayPal and Western Union. For long-term wholesale partners, flexible payment terms can be negotiated. Contact our sales team for details.
Q: Do you provide third-party inspection reports?
A: Yes. We can arrange third-party inspection such as SGS, TÜV or BV before shipment. Mill test reports, material certificates and dimensional reports are also available for every order.
Q: How do I determine the correct gasket thickness for my application?
A: Thinner gaskets offer better resistance to creep and high bolt stress but require very flat flanges. Thicker gaskets compensate for flange misalignment, warpage and surface irregularities. Kaxite Seals technical support can perform a flange condition analysis to recommend the optimal thickness.
Q: What is the main difference between Compressed Non-Asbestos and Expanded Graphite gaskets?
A: CNA gaskets are composite sheets of organic fibers and elastomers, offering good mechanical strength for a broad range of industrial fluids. Expanded Graphite gaskets provide exceptional thermal conductivity, natural lubricity and superior sealability at high and cryogenic temperatures.
Q: Can I reuse a gasket after disassembling a flange connection?
A: Gaskets should never be reused. Once compressed during installation, a gasket undergoes plastic and elastic deformation. Upon removal, its internal structure is permanently altered and reusing it can lead to a leak path. Always use a new certified gasket for every reassembly.
Q: What are spiral wound gaskets, and when should they be used?
A: Spiral wound gaskets are semi-metallic gaskets constructed by winding a pre-formed metal strip and a soft filler material in a V-shape around a center ring. They are the industry standard for high-pressure, high-temperature applications in oil & gas, chemical and power plants.
Q: Are PTFE gaskets suitable for all chemical applications?
A: PTFE offers near-universal chemical resistance, but molten alkali metals, certain fluorine compounds and some halogenated organics at high temperatures can affect it. PTFE is also subject to cold flow under sustained load. Kaxite Seals offers filled PTFE compounds for improved creep resistance.
