We're looking at roughly 170 days or so of continuous with that galvanized coating, which is better than most plain steel fittings you'll find for comparable hydraulic work, especially if you're running medium carbon steel like this through a system that sees -20°C to 120°C cycling.
It actually handles high working presure pretty well—just know that BSP and BSPT threads (we stock both) aren't interchangeable, so double-check your pipe standard before ordering because mixing them will cause leaks you can't fix with more torque.

What it does is it uses a hexagon head (22mm across flats on the 1CB model) so you can cinch it down with a standard wrench without slipping, and we've got those OEM customization requests rolling in from guys who want shorter threads or different plating—just send us the drawing.

Three hundred units is roughly what we've got on the shelf for the 1DB at the moment, and we've been shipping these to folks running hydraulic presses and pipe jacking rigs for about eight years now, with ISO 9001 certifcation covering the whole process.

You wouldn't want this for anything involving high-vibration, really flexible line connections like you see on some pneumatic setups—teh carbon steel is sturdy but it's not constant movement, so keep it in rigid installations.
Anyway, we just ran HPLC on a batch last week (COA's availble on request) and the traceability ties back to specific melt numbers, but if you need the TDS for your safety paperwork, give us a nudge since we usually have that ready within two business days.
Our MOQ for these hydraulic fittings is typically 500 pieces per size, but we can discuss lower quantities for first-time orders or specific color/surface needs.
Standard custom orders usually take 20-30 days after sample approval, depending on batch size and any special surface treatment requirements.
Yes, the factory is ISO 9001 certified, and we can supply mill test certificates for the medium carbon steel upon request.
Correct, the galvanized coating holds up well in that range, but for continuous use above 100°C, we'd suggest checking for any zinc degradation over time.
They come in polybags inside cartons, with foam separators between layers to keep the threads and hex heads from scratching during shipping.
