Dalian Chengyi Mechanical Co., Ltd supplies hydraulic fittings made from stainless steel 304/316 and carbon steel grades. The fittings comply with DIN 2353 and EN ISO 8434‑1, covering a broad range of fluid power connections. Working pressure is specified between 10 MPa and 63 MPa, suitable for high‑pressure hydraulic circuits. Available connection sizes cover nominal diameters from 6 mm to 42 mm.
Typical thread standards are ISO 228 for metric fittings and BSP for British‑style connections. Common fitting types include WALFORM cutting‑ring, weldable straight stud, and forged tube couplings. Standard torque values for stainless steel connections are around 30 Nm, while carbon steel fittings often require 25 Nm. Surface finish is usually Ra ≤ 1.6 µm to ensure sealing integrity.
These components are used in oil‑and‑gas extraction equipment, chemical processing plants, and heavy‑machinery hydraulic systems. Buyers frequently request custom kits or specific sealing kits, and the supplier notes flexibility in order size. Shipping can be arranged under FOB or CIF terms, with packaging in sturdy wooden crates to protect the fittings.

Before confirming an order, verify the material grade, standard compliance, working pressure, and thread type required for your hydraulic system. Request the relevant test reports or certificates to confirm that the fittings meet DIN 2353 and EN ISO 8434‑1 specifications. Ensure that the nominal diameter and connection type match the design of your equipment.
Discuss logistics early, including the expected lead time based on the order quantity and any required customisation. Agree on Incoterms such as FOB or CIF, and clarify preferred payment methods, whether by letter of credit, telegraphic transfer, or other terms. Confirm packaging details, such as crate dimensions and protective padding, to prevent damage during transit.
Arrange for a third‑party inspection if you need independent verification of dimensions, material composition, and pressure rating. The supplier can supply Type Test Reports and, upon request, certificates of conformity for each batch. Maintaining thorough documentation will smooth customs clearance and ensure the fittings perform reliably in service.
