We keep about 200 pieces in stock for the common sizes—1/2" to 4"—but the 6" and up usually require the full 30-day lead time, sometimes 35 if the galvanized finish is requested, so check before ordering if you're in a hurry.
These are forged from ASTM A865 carbon steel, which basically means they hold up better under vibration than cast alternatives, and the NPT threads are cut clean enough that you won't fight them during installation, though the BSPT option is tighter for European systems.
The 3-year manufacturing defects, but not thread damage from overtightening—most buyers go with the Sch40 for standdard water lines, while Sch80 is better for industiral steam application where pressure spikes are common.
4, we offer three surfce finishes: black for indoor dry systems, galvanized for outdoor or wet environments, and polish which is mostly for visible plumbing where aesthetics matter, though none of these are food-grade so don't use them for potable water lines.
MOQ is 100 pieces for standard sizes, but if you need half couplings with squared-off end for tank welding, that's typically a custom run and the lead time jumps to 45 days or so.
MOQ for custom thread types like BSPT is still 100 pieces, same as standard. We can do mixed thread types in one order as long as total hits 100.
Yes, we carry TUV certification for our Sch80 heavy series. That covers the full range from 1/2" to 12". Just let us know which size you need certified.
Standard rating matches Sch40 wall thickness, good for typical water lines. Extra-Strong is Sch80, thicker wall, handles higher pressure. If you're unsure, we can recommend based on your system specs.
Yes, we offer galvanized finish. Standard lead time is 30 days, same as black finish. No extra delay unless you need a huge batch — then we'll confirm.
Smaller sizes go in cartons or wooden crates. For 12-inch, we use heavy-duty plywood crates with foam inserts to prevent thread damage. All packed per export standards.
