Why this coupler
- Flat face, no-spill design — which means virtually no fluid loss on disconnect and minimal air inclusion on connect, keeping systems clean.
- Flat faces wipe clean — which means you can wipe both halves before connecting, critical in dirty field environments.
- Bidirectional flow — which means oil can flow either direction through the coupling.
- Safety locking sleeve — which means protection against accidental disconnection under load.
- 1,200-hour salt-spray tested — which means proven corrosion resistance with no white or red rust.
- Zinc-nickel plated carbon steel — which means a tough, corrosion-resistant body at a working-tool price point.
Frequently asked questions
What does this connect to?
It meets ISO 16028 flat face and connects with matching 3/4" FF Plus plugs.
What pressure is it rated for?
Rated to 5075 PSI maximum working pressure.
Why a flat/flush face?
Flat-face couplers spill almost no oil on disconnect and include almost no air on connect, and the faces wipe clean — ideal for keeping hydraulic systems contamination-free.
Pair this coupler with a matching 3/4" FF Plus plug for a complete connection. Ideal for portable hydraulic tools, construction and utility equipment, and field maintenance.
Why FF Plus vs standard flush face: The FF Plus line is the upgraded option — offered in both nickel-plated steel and 316 stainless, with bidirectional flow, a Connect-Under-Pressure option, and 1,200-hour salt-spray corrosion testing. It exceeds the basic flush-face spec while remaining ISO 16028 intermateable.
