Import Din-4sp — Buy in Bulk from Supplier in China

The DIN-4SP hose is a high-pressure hydraulic hose constructed to DIN 4551 standards, featuring a synthetic rubber inner tube and four layers of high-tensile steel wire braid reinforcement. It is rated for a working pressure of 31.5 MPa and a burst pressure exceeding 125 MPa. The nominal bore sizes range from 6.4 mm to 25.4 mm, making it suitable for demanding hydraulic systems where durability and resistance to pulsation are critical.

The hose’s four-layer steel braid provides superior burst resistance and kink protection compared to lower-class hoses like DIN-4SH. The outer cover is formulated for abrasion and ozone resistance, suitable for outdoor or heavy machinery use. While the listing confirms oil resistance, it does not specify whether the inner tube is compatible with synthetic esters or phosphate esters. Temperature performance is not stated but typically aligns with standard DIN-4SP limits of -40°C to +100°C.

This hose is commonly specified in construction, mining, and heavy machinery applications where hydraulic systems operate above 20 MPa. Industries such as crane manufacturing, hydraulic presses, and mobile equipment rely on DIN-4SP for reliability under cyclic pressure. The listing mentions flexible packaging and shipping options, but exact MOQ, lead time, and incoterms are not provided and must be confirmed with the supplier before procurement.

Hengshui Baili Hose Co., Ltd. is a manufacturer based in Hengshui, Hebei Province, China, with a physical address on North of Ning An Road. The company is listed as a harbor-tier supplier, indicating a basic level of platform verification. There is no public information on years in operation, workforce size, or export history. The supplier has not provided response rate or average response time, suggesting limited buyer communication activity on the platform.

The company specializes in industrial hydraulic hoses and related fittings. The listing does not confirm certifications such as ISO or SGS, nor does it list client names or production capacity. Any claims about certifications or volume output must be verified directly with the supplier. The absence of response metrics and detailed profile data means buyers should treat this as a manufacturer with limited digital transparency.
