Diaphragm
Guizhou Dazhong Rubber Co.Ltd, based in Guiyang, China, manufactures diaphragms for automotive brake systems. The component transmits pressure within air chambers, helping to maintain consistent braking performance. It is engineered to meet OEM specifications for a range of vehicle models. The supplier notes that the diaphragm can withstand extreme temperatures and pressures typical of brake applications.
The diaphragms are produced from rubber compounds that offer excellent wear resistance and durability. In the industry, similar diaphragms are commonly made from nitrile (NBR) rubber with a hardness around 70 Shore A, an operating temperature range of -40 °C to 150 °C, and a pressure rating up to 2 MPa. Typical packaging for bulk orders is cardboard cartons. These typical values help buyers compare performance across manufacturers.

Sourcing Diaphragm from Guizhou Dazhong Rubber Co.Ltd - China Import Guide
Before placing an order, verify the material composition, hardness and certification documents provided by Guizhou Dazhong Rubber Co.Ltd. Request a sample or laboratory test report to confirm wear resistance and temperature performance. Confirm that the diaphragm dimensions match the OEM requirements of your vehicle or equipment, and obtain a detailed drawing if the part is custom‑made.
Discuss logistics early by agreeing on the incoterm - commonly CIF or FOB for bulk rubber components - and ask the supplier to quote the expected lead time for production and shipment from Guiyang. Payment terms are typically T/T after a pro‑forma invoice, but negotiate any advance deposit requirements. Ensure that the shipping method accommodates the bulk packaging described.
Arrange a third‑party inspection at the factory or upon arrival to verify dimensional accuracy, hardness and overall workmanship. Request the supplier’s test certificates for pressure and temperature resistance, and keep records of the inspection report for customs clearance. Proper documentation will streamline the import process and reduce the risk of non‑conforming parts.
