So you're looking at the SAE 100 R2a ferrule fitting for high-pressure lines, and the first thing most buyers ask is about the steel quality—we use medium carbon steel, 20# specifically, which gives you good balance of toughness and machinability, and the galvanized surfce treatment handles corrosion better than plain black oxide in my experience, especially if your shop sees moisture or salt air.
We've been shipping these for years to machine shops and heavy equipement rebuilders, and one thing nobody tells you upfront is that the welding connection on these ferrules needs a clean prep to seat right—it's not a push-on fitting, so your crew should be comfortable with a torch or a proper welding jig, and for that reason it's better suited for permanent installations than quick-swap field repairs, just so you know.
The working pressure is high-pressure systems, and the temperture range covers -20°C to +120°C, which covers most hydraulic circuits in industrial presses and excavators, but I'd caution against using this in steam lines or anything above that range—the galvanizing can degrade faster than you'd expect around 130°C or so, and that's not something we'd warranty past the spec.
Lead time is about 60 days on a standard order, but we usually have stock on the common sizes like 10mm and 12mm thread options—just confirm the metric or imperial thread standard you need when you send the PO because the die sets are different between DIN and JIS variants, and we can't swap them mid-production without a delay.
For documentation, our company provide a full COA with every batch, and the ISO 9001 certifcation covers the whole manufacturing process from CNC machining to the multiple inspection stages, so you'll get a traceable lot number and the galvanized coating thickness in microns on request—most procurement teams find that's enough for their compliance files, but our company can also add your logo printing to the packaging if that helps with inventory tracking.
We don't have a fixed MOQ listed here, but typically for standard sizes we can do small trial orders. For custom logo printing or special thread specs, we'd need at least 500 pieces to make it cost-effective.
Yes, we're ISO 9001 certified and every batch comes with a material test report and dimensional inspection records. Just let us know what specific documents you need, and we'll include them with the shipment.
The galvanized coating gives excellent corrosion resistance for most industrial and outdoor hydraulic systems. For direct saltwater exposure, we'd recommend a heavier zinc coating or a different finish — just talk to us about your specific conditions.
Standard metric or imperial threads ship within 60 days. For custom threads like BSP or NPT, add about 10–15 more days for tooling and setup. We'll confirm the exact timeline when you place the order.
We use standard export packaging — usually bulk in strong cartons or pallets, with each layer separated to prevent scratching. If you need individual polybagging or custom labeling, we can do that at no extra charge for larger orders.
