You’ll see these most often in fire suppression lines or hydraulic valve assemblies where a leak would shut down an entire operation—they’ve got to hold pressure reliably under vibration and temperature swings, and the nickel plating means they won’t pit or corrode after a few years in a damp mechanical room.
Thread standdard cover DIN, ANSI, GB, JIS, and BSW across 1/2-inch to 2-inch sizes in BSP, NPT, and PT, so you can pretty much match whatever legacy system or international spec you’re dealing with; we usually have stock on the common sizes but confirm lead time for oddballs like 1-1/4 BSP.
Surfce treatment is nickel plated over a hexagon brass body, which gives a harder finish than raw brass and makes wrenching easier without galling—most buyers go with the male-female connection style because it simplifies ordering for both ends of a joint.
3.2 grams or so for a 1/2-inch fitting, give or take depending on the thread type, and the hex head lets you torque it without rounding off (check the torque spec for NPT threads in particualr, they’re tighter than BSP).
It’s not great for potable water lines—the nickel layer can flake after repeated thermal cycling, and we’ve seen it fail faster than stainless in hot recirculation loops, so stick to brass or stainles for drinking water appliction.
Samples are free, but we charge actual freight; origin is Taizhou, and the HS code is 8481804090 if you need it for customs.
We do offer free samples so you can test the quality first. As for MOQ, that typically depends on the size and thread type, but we're pretty flexible—just let us know what you need.
For an order of 500 pieces, lead time is usually about 15-20 working days, depending on the thread standard and size mix. We can speed it up if it's urgent—just check with us.
Yes, we can provide a material test report and a certificate of conformity upon request. Just let us know what specific docs you need when placing the order.
Absolutely—the 1/2" size is available in BSP, NPT, and PT. You just need to specify the thread standard when ordering, and we'll make sure it's exactly what you need.
They come in cartons with inner plastic bags, and we can add bubble wrap for extra protection. Store them in a dry, cool place away from moisture, and the nickel plating should stay shiny for a long time.
