Used Sin Marca Flanges

Choose a flange that matches the equipment’s pressure rating and connection style (weld‑neck, slip‑on, or threaded). Weld‑neck or bolted flange assemblies with the correct gasket are common for high‑pressure hydraulic lines.

Measure flange OD, bolt circle diameter, bolt count and hole size, plus face type. Cross‑check OEM part numbers or technical drawings to ensure exact fit.

Carbon or alloy steel with protective coatings is typical for strength. Use stainless or duplex steels where corrosion resistance is critical (salty or chemical environments).

Ship flanges on pallets or in crates with face protectors, rust inhibitor, and secure strapping. Include gaskets and fasteners separately or boxed and insure against transit damage.

Inspect for leaks, corrosion, and cracked welds; check and retorque bolts to spec after initial service; replace degraded gaskets, studs or seals as needed.

Provide the supplier with the loader’s serial number, OEM flange part number or detailed measurements and pressure/temperature specs. Ask for material and rating certificates when in doubt.
