Basically what we've got here is a DIN-standard hydraulic elbow made form medium carbon steel, zinc-galvanized for corrosion resisance—the kind of thing that holds up in construction machinery day after day. Most buyers go with teh female connection because it's just more secure for high-pressure lines, and the round head makes installation straightforward.
Lead time runs about 30 days from order, give or take, and our MOQ is 100 pieces. That's pretty standard for OEM supply from China. You'll get a COA with each batch, and our company can usually accomodate custom branding—just check on the lead time if you need something specific. 3. We've had some customers ask about pressrue ratings, and while we don't list a specific PSI on every fitting, these are tested for typical construction machinery loads. The zinc coating is actually thicker than what you'd find on many general-purpose fittings, which matters if your gear sees a lot of moisture or road salt.
One thing that catches people is the medium carbon steel versus stainless—it's stronger for the weight but not suited for highly acidic environments. 5. Also, the 1/2-inch size moves fastest, but we can do custom thread pitches if your gear runs metric (usually 2-4 weeks extra). The round head design means it fits standard wrenches, which saves time on assembly lines.
We don’t publish a one-size torque spec because it depends on your specific thread size and seal type. For standard DIN connections, we recommend torquing to the fitting manufacturer’s guidelines for the mating port — usually between 25-50 Nm for common sizes, but always verify with your system’s requirements.
Yes, the zinc galvanized coating gives good corrosion resistance for typical outdoor use on construction equipment. If you’re dealing with highly corrosive conditions like salt spray or constant submersion, we’d suggest upgrading to a stainless steel version — just let us know.
Absolutely, we can supply a mill test report for the medium carbon steel batch upon request. Just mention it when you place your order, and we’ll include it with your shipment at no extra charge.
The 30-day lead time applies to the total order quantity, not per size. So if you order 100 pieces across different sizes, it’s still 30 days from order confirmation. We’ll confirm exact timing once we have the size breakdown.
Yes, OEM branding is available — we can print your logo or mark the fittings per your specs. Custom packaging is also fine, just share your requirements and we’ll adjust the quote. MOQ for custom branding is still 100 PCS.
