Titan 432-644 Ferrule
Hydra/PowrTex part 432-644 is a replacement ferrule used in fluid connections on compatible Hydra M, Hydra Pro Super, and PowrTex 15:1 equipment. It compresses around tubing to create a leak‑tight seal when used with a fitting nut. Replacing a worn, cracked, or damaged ferrule restores leak‑free operation and prevents fluid loss or contamination.

Ferrule (432-644) for Hydra M, Hydra Pro Super & PowrTex 15:1
The 432-644 Ferrule is a precision component used in compression‑type tube fittings on compatible Hydra M, Hydra Pro Super, and PowrTex 15:1 equipment. When the fitting nut is tightened, the ferrule compresses onto the tubing, creating a strong, leak‑proof seal that withstands high pressure and vibration.
Over time, ferrules can become worn, cracked, or lose their grip due to repeated assembly/disassembly, thermal cycling, or overtightening. A damaged ferrule may cause leaks, pressure drops, or complete fitting failure. Replacing it with a new 432-644 ferrule restores a reliable seal and ensures safe, efficient operation of your fluid system.
What it does and when to replace it
| Creates leak‑tight seal | Compresses onto tubing to prevent fluid escape |
|---|---|
| Withstands pressure | Maintains seal under high operating pressures |
| Resists vibration | Holds tubing securely even with machine movement |
| Allows disassembly | Can be reused if not over‑tightened, but replacement is recommended for reliability |
| Visible damage | Cracks, splits, or deformation of the ferrule |
|---|---|
| Leakage | Fluid seeping from the fitting |
| Loss of grip | Tubing can be pulled out of the fitting |
| Overtightened | Previous over‑tightening may have work‑hardened the ferrule, reducing sealing ability |
| Disassembly | Whenever a connection is broken, replacing the ferrule ensures a fresh seal |
