ISO16028 FF Series Flat Face Hydraulic Quick Couplings 1 Inch Steel High Pressure Connectors

Basically, you're looking at a 1-inch flat face coupling built for high-flow hydraulic systems, rated between 3000 and 5000 PSI depending on the size you pick — most buyers go with the 1-inch for heavy equipement like excavators or oil rigs. flat face design keeps spillage down to about 0.006 to 0.1 ML per disconnect, which is pretty much standard for anyone tired of cleaning up messy drips.

It's not ideal for low-pressure or low-flow application, say under 3 GPM, because the poppet valves are designed to open automatically under pressure and won't seal properly without it. We see these used mostly on construction machinery and hydraulic tool setups where you're coupling and uncoupling hoses multiple times a day.

Zinc-chromate plated steel with NBR seals handles temps from -20°C to +120°C, and teh hexagon head makes tightening with a standard wrench straightforward — no special tools needed. 0.006 to 0.1 ML spillage is the range we usually see on our COAs, but confirm lead time if you need tighter tolerances (check batch specs).

Trust comes down to interchangeability: this one fits Parker 6600, Faster ANV, Aeroquip 5600, and Hansen HA 15000 series, so it'll swap right into existing systems without re-plumbing. We've been shiping these for years, and the galvanized surface treatment holds up better than plain steel in wet environments or salty air (think offshore rigs).

MOQ is typically 50 units or so on the 1-inch size, but smaller orders might take 20 days or so depending on stock — we usually have stock, but confirm lead time. One thing to ask for is the seal matrial spec on your lot, as NBR can harden faster if you're running hydraulic oil above 100°C for extended periods.
