When you're building out a coolant line on a heavy truck or securing an air intake in a shop environment, what you need is a clamp that won't let go under vibration—these black round heads handle that pretty well, they're basically the workhorse for mechanics who deal with constant thermal cycling.
They're made from 301SS or 316SS depending on your corrosion needs, with a band width that runs form 12.7mm all the way up to 178mm and a thickness of just 0.64mm—that's thin enough to flex into tight spots but still holds firm—and the clamping range goes from 0.44" to 7" give or take, so you'll cover most common hose sizes without swapping parts.
The black finish isn't just for looks, it actually helps with identification on dark assemblies, though one thing to keep in mind is that without surfce treatment corrosion resistance sits at about 720 to 1000 hours—it's fine for dry or mild environments but don't expect it to survive submerged salt spray indefinitely, that's not what it's for.
These follow DIN and GB standards so they'll thread into existing female connections without fuss, and we usually ship 500 pieces per carton—confirm lead time if you need a full pallet because stock fluctuates.
Anyway, the 12.7mm band width is the most common pick for automotive work, most buyers go with that unless they're clamping larger indutrial ducts where the 178mm version makes more sense.
MOQ is typically one carton, but we can split for smaller runs if you ask.
Our standard MOQ is one carton, which holds 500 pieces. If you need less, we can sometimes split a carton, but the pricing might be a bit higher.
Yes, we can share a third-party salt spray test report upon request. The 720h to 1000h range depends on the stainless steel grade you pick—316SS hits the higher end.
Absolutely, we can make them in 316SS with the same 0.64mm thickness and round head. Just note that 316SS will cost more than 201 or 304 options.
For stock sizes, lead time is usually 7 to 15 days. If you need custom clamping ranges or band widths outside the 0.44" to 7" range, expect 20 to 30 days.
They come loose in a carton, 500 pieces per box, with no individual wrapping. If you need them bagged or tagged separately, we can do that, but it adds a small packaging fee.
