Starts to really matter when you’re swapping out cheaper zinc-plated fittings that corrode inside six months—our galvanized treatment on carbon steel holds up noticeably longer in humid or wash-down environments, tested to above 72 hours in salt spray.

The round head and female connection style make installation straightforward with standard wrenches, no special adapters needed, and we’ve found the #12 and #16 sizes are the most commonly reordered for heavy equipement lines.

Most buyers go with the DIN standard for European machinery or ANSI for domestic—either way, we keep roughly 500 units on hand for each size form #6 through #16, so typical lead time is 10-14 working days or so.


Presure rating isn’t just a number on a label—it’s high enough for 4,000-psi systems without weeping at the threads, but we don’t recommend these for food-grade lines unless you add a stainless option (we don’t stock that variant).

Also, OEM custom is pretty much standdard here; we produce with your marking or thread length within 2-3 weeks, and the COA shows actual batch purity and torque specs—no copy-pasted blanks.

Basically, you get consistent galvanized finish that doesn’t flake off, better than usual black-oxide stuff, and the #10 and #8 sizes ship fastest since we generate those weekly.
We offer sizes #6, #8, #10, #12, and #16 in this series, all with a female connection type and galvanized finish for corrosion resistance.
Yes, OEM is available. Just send us your specs or drawings, and we can tailor the fittings to match your system requirements.

Sure, we can supply material certificates and test reports for the carbon steel and galvanized surface treatment upon request.
Standard export packaging includes individual poly bags, then sturdy cartons with palletizing and stretch wrap to prevent damage during shipping.
