The offering is a series of hydraulic hose fittings conforming to the SAE 21691 standard, designed with flange connections for high‑pressure fluid transfer. The fittings are manufactured from either carbon steel or stainless‑steel grade 304, providing options for corrosion‑resistant applications. Sizes covered span DN6 to DN8, with bore options of 1/4 in and 3/8 in, and feature BSP threaded ports on the flange. The part numbers follow the SAE coding, for example 21691‑04‑04 for a DN6 1/4 in fitting.
Carbon‑steel versions deliver strength suitable for most hydraulic circuits, while the stainless‑steel 304 variant is preferred where moisture or chemical exposure is a concern. Typical pressure ratings for SAE 21691 fittings reach up to 250 bar, aligning with industry expectations for medium‑duty hydraulic systems. The flange dimensions listed in the supplier data (e.g., A 30 mm, B 4.6 mm, H 40.5 mm for the DN6 model) match standard dimensions found in European and North‑American equipment. These fittings are usually supplied as bulk coils or packed in wooden crates, a common practice for large‑volume orders.
Primary users include equipment manufacturers, OEMs and maintenance service providers in construction, mining and mobile hydraulics sectors. Buyers should verify the material certification and request pressure‑test reports before committing to a purchase. Trade discussions normally address packaging size, Incoterms such as FOB Shanghai or CIF destination, and payment terms, all of which are negotiated per shipment.

Importers should first obtain the SAE 21691 conformity certificate and a material test report for the selected carbon‑steel or stainless‑steel variant. Verify the flange dimensions, bore size and pressure rating against the system design, and request a hydrostatic test record to ensure compliance with the required performance level.
Shipping is usually arranged under FOB terms at a major Chinese port such as Shanghai; buyers need to confirm the exact loading port, expected lead time - typically four to six weeks - and negotiate payment conditions that align with both parties’ risk tolerance. Packaging in wooden crates or coiled bundles allows efficient container utilisation and protects the fittings during transit.
Upon receipt, a third‑party inspection should confirm the correct material grade, dimensional tolerances and thread integrity, and include a pressure‑test at the rated working pressure. Secure the inspection report together with the original test certificates and any required import licences before releasing payment to mitigate quality and compliance risks.
