The GOT‑420 corrugated metal gasket is formed by die‑pressing a metal flat ring into a concentric waveform coil. Its outer surface can be finished with expanded graphite or PTFE for chemical resistance. The metal core is offered in carbon steel 1.1003/1.0038, stainless steel grades SS304/304L and SS316/316L. Thicknesses from 0.5 mm up to 4 mm are selectable, and the corrugation pitch can be 3, 4 or 6 mm.
These dimensions allow the gasket to accommodate various flange gaps. Typical industry practice limits operating pressure to about 1.5 MPa for low‑pressure seals. Standard tolerance on thickness is ±0.05 mm, ensuring consistent compression. The product complies with ASME B16.20 design standards, a common benchmark for metal gaskets.
The gasket is suited to large‑diameter flue‑gas ducts, boiler exhausts and other high‑temperature low‑pressure applications. Its soft overlay reduces friction and helps maintain a seal under moderate bolt loads. Buyers such as power‑generation plants, petrochemical refineries and HVAC contractors typically request bulk quantities. Specific MOQ, price and lead‑time are not listed, so importers should contact the supplier to confirm trade terms.

Before placing an order, verify the exact metal grade, overlay material and thickness required for your flange configuration. Request a mill test report and any relevant certification to ensure the product meets your project specifications. Clarify the MOQ, packaging format and any special handling instructions with Ningbo Gaote Sealing.
Logistics for shipments from Zhejiang typically use the ports of Ningbo or Shanghai. Importers should confirm the preferred Incoterm - often FOB or CIF - and discuss lead‑time expectations, as the source does not provide a schedule. Payment terms are usually negotiated per transaction; ask the supplier to outline acceptable methods such as T/T or LC.
Quality assurance commonly includes hardness testing, dimensional inspection and visual checks of the overlay layer. Arrange for a third‑party inspection agency to verify compliance with ASME B16.20 and the agreed specifications before cargo release. Retain all test certificates and inspection reports as part of your import documentation.
