Running at 60,000 psi is pretty much the upper limit for most of these, and we've got that covered for the 1/4", 3/8", and 9/16" sizes, though the 1" drops to 43,000 (2964.7 bar or so), which is still plenty for most buyers working with high-pressure loops.
Basically, it uses a coned-and-threaded connection with anti-vibration components built into the hex head design, so you're not chasing leaks when the system cycles — (we usually have that polished finish as standdard, it's easier to clean after testing).

Materail is either 316 stainles or Alloy 826 depending on your corrosion needs, and it handles from -423°F straight up to 1200°F, but don't push those extremes simultaneously for long runs; it's just a fact of metallurgy.

What it does is give you compliance with ANSI, GB, and JIS in one fitting, which actually saves headaches if you're spec'ing for multiple plants, and the MOQ is one piece (OEM customiaztion is pretty straightforward, usually 2-3 weeks lead time).

We'd need to know your thread configuration and exact material preference (316 is better for general use, but Alloy 826 holds up better if you're cycling near those cryo temps), and also whether you need a TDS or COA with order — in most cases we include the HPLC report.
Anyway, for that RFQ, just confirm head size (1/4, 3/8, 9/16, or 1 inch) and quantity, and we'll send a quote within a day or so — no minimum past that single piece.
MOQ is just 1 piece, so you can order exactly what you need for testing or small runs—no bulk requirements.
Yes, we supply mill test reports with every batch. Just let us know if you need specific certifications like EN 10204 3.1.
Standard lead time is around 2-4 weeks after design approval, depending on quantity and complexity. We can expedite if needed.
Yes, they follow ANSI/GB/JIS standards for coned-and-threaded connections, so they work with common high-pressure tubing systems.
We pack them in individual plastic bags or boxes to prevent scratches. For bulk orders, we can use export-grade cartons or crates.
