Import A Series Hydraulic Quick Couplings — Buy in Bulk from Supplier in China

The A Series Hydraulic Quick Couplings from Hebei Sinopulse Tech Group Co., Ltd. comply with ISO 7241-1 part A, offering interchangeability with standard A-series couplings used in global hydraulic systems. Connection is achieved by pulling back the sleeve, while disconnection requires pulling back the female sleeve, with both actions requiring a no-pressure state as the poppet valve shuts off flow automatically. The couplings are constructed from high-grade carbon steel with heat-treated wear parts, ensuring durability in demanding hydraulic applications.

Backup rings are made from PTFE, while seals utilise polyurethane and NBR compounds, providing reliable performance across a temperature range of -25°C to +100°C. These materials are standard for hydraulic couplings in moderate-pressure systems, where resistance to wear, chemicals, and temperature fluctuations is critical. The design adheres to industry norms for quick-connect fittings, allowing for rapid assembly and disassembly without tools.

These couplings are typically used in construction machinery, agricultural equipment, and industrial hydraulic circuits where frequent connection and disconnection of lines is required. Buyers in these sectors prioritise compatibility with existing ISO 7241-1 A-series systems, as well as the ability to handle standard working pressures without leakage. Suppliers like Hebei Sinopulse Tech Group Co., Ltd. cater to importers seeking bulk shipments with consistent interchangeability and material specifications.

Hebei Sinopulse Tech Group Co., Ltd. is based in Handan, Hebei Province, China, with its facility located in the Feixiang Industrial Zone. The company operates in the hydraulic fittings sector, specialising in ISO-compliant quick couplings for industrial and mobile applications. Its profile indicates a focus on manufacturing components that meet international standards, as evidenced by the A Series couplings’ adherence to ISO 7241-1.

The supplier holds a harbor trust tier, which reflects a baseline verification level for export-oriented businesses in China. While the listed response rate is currently at 0.00, this may indicate a new or temporarily inactive account rather than a lack of operational capacity. Buyers are advised to contact the supplier directly to confirm current responsiveness, production lead times, and technical support availability for hydraulic coupling inquiries.
