You're looking at the DIN/SAE round head hydraulic fittings with M12X1.5 threads, and we've been shipping these for years to industrial buyers who need relaible pipe line connections. They're medium carbon steel, galvanized—white or yellow finish—so rust isn't a concern in most shop environments. Basically, galvanizing holds up well even with exposure to moisture or mild chemicals.

These are male connection type fittings, and the thread is M12X1.5—pretty standard for European-style hydraulic systems. The round head shape is what it is; it's not designed for wrench-heavy torque application, so don't use them where you'd need a hex head for extra. We usually have stock on the 1C9 and 1D9 models, but confirm lead time if you need over 50,000 pieces or so.

With a production capacity of 5 million pieces per month, our company can handle large runs without breaking a sweat. But also, small batches aren't an issue—our MOQ for custom orders is typically around 1,000 pieces. Customization is available (OEM services), though we'll need a drawing or sample to match your spec exactly. Turnaround is usually 20 days or so for custom stuff.
Compliance is handled—we've got ROHS and SGS certifications on file, and our company provide a COA with each shipment. The galvanized surfce treatment isn't just cosmetic; it actually extends the working life in demanding environments (think hydraulic presses or assembly lines). We don't recommend these for food-grade or high-purity fluid systems, though—that's a different ballgame.

Anyway, for ordering, we ship FOB from our warhouse. Freight depends on quantity, but for a standard pallet of yellow or white fittings, it's roughly $50-80 to most US ports. We usually have stock on the M12X1.5 threads, but double-check the color and quantity when you send the PO.
We can handle small orders, but typically MOQ starts around 1,000 pieces for standard sizes like these M12X1.5 fittings. For custom specs, we'll negotiate based on the complexity.
For standard white or yellow galvanized fittings, lead time is about 15-20 days after order confirmation, given our production capacity of 5 million pieces per month. Custom orders may take a bit longer.
Yes, we include ROHS and SGS test reports for every batch of these medium carbon steel fittings. Just request it when placing the order, and we'll send the docs along.
We offer OEM customization, so we can adjust the thread size to your specs. Keep in mind that changes may affect the price and lead time, since it's not a standard option.
We pack them in sturdy cartons or pallets, usually with plastic bags inside to prevent moisture damage during shipping. For long-term storage, keep them in a dry place to avoid corrosion.
