We don't just ship fittings. We test them first. 🛠️✅
Here's a look at our seal test bench at Ruihua Hardware Factory — where compression fittings get pressure-tested before they ever go into a box.
Why does this matter?
Because the only leak you want is a conversation leak in your supply chain, not hydraulic fluid on your shop floor. 😄
What we test:
🔧 Compression / ferrule-type hydraulic fittings
🔧 Carbon steel & stainless steel options
🔧 M14 to M42 sizes, custom specs welcome
🔧 OEM/ODM projects with engineering support
Every batch gets tested. Every shipment gets checked. That's the RH way.
