We’ve been running these 27811 connectors through high-presure cycles for a while now, and they hold up pretty well even under constant vibration—the chrome plating on low carbon steel gives it a solid lifespan in most hydraulic setups.
Sizes range form 7/16" to 1-1/16", and you can get either metric or inch threads depending on your system—most buyers go with the 1-1/16" for heavy lines, but it’s not a bad idea to check lead time since MOQ is negotiable.
It’s not really suited for low-pressure or non-industrial application, but for high-pressure hydraulic lines—say 3000 psi or so—the DIN standard threading (usually a tight tolerance) means less risk of leaks compared to generic fittings.
The tempearture window is roughly -20°C to 120°C, which covers most shop floor conditions, and the round head design helps with hand-tightening in tight spots (we’ve had a few customers mention that).
Ordering is straightforward: just specify size and thread type, and we’ll provide a COA with SGS or ISO9001 certs if needed—no need to overthink packaging, it’s standard export stuff.
About 50 units or so is typical for a first run, but we can adjust—just confirm the lead time before you commit.
Our MOQ is negotiable, so you can start with a small trial order to test the fit and performance in your hydraulic system.
Yes, we include ISO9001 and SGS certification copies with every order, so you have the quality docs for your records or audits.
Absolutely, the 27811 series supports both metric and inch threads—just specify which you need when ordering.
We use standard export packaging—each connector is individually wrapped and boxed with cushioning to avoid scratches or thread damage during transit.
They're rated for -20°C to 120°C, so they work fine in most industrial hydraulic setups without losing seal integrity.
