High Quality 316L Stainless Steel Three Way Male Thread Fittings with Double Ferrule Design

So you've been chasing a leak on that manifold for the last two days and the threads are all wrong—that's why we're switching to teh double ferrule design on these 316L three-way fittings, and they handle up to 20MPa easily which is roughly what your line runs at.

It's a hex head, male thread connector with an untreated surface—most buyers in the oil and gas sector actually prefer it that way since passivation or electropolishing adds cost they don't always need, and the double ferrule grip on the pipe means you're not torquing the body as much during install, which matters when you're working in tight spaces.

These work with air, water, and oil fine, up to about 230°C, but don't try them with steam or corrosive chemicals unless you've verified the fluid compatibility yourself—the 316L is good but untreated surfaces can pit under certain conditions. We stock the 01 through 06 specifcation range usually, but the smaller sizes (01 and 02) sell faster and we get lead times around 20 days or so if we're out.

And if you're ordering more than 50 units, ask about bulk pricing—we typically knock 8-12% off if you're not in a rush and our company can combine it with a standerd production run (usually 2-4 weeks for OEM orders). Some buyers ask about custom hex sizes or shorter threads, but we don't do one-offs on these; the tooling is set for GB standard.

Anyway, the double ferrule design is what you're really buying—it's way better than straight compression fittings for this presure range and it's actually what a lot of the instrument air systems I've seen use, so you'll have fewer callbacks. Just confirm pipe OD when you order, since the 01-06 range covers about 6mm to 14mm or so and ferrule grip is specific to each size.
