Typical faults in the spray gun: leakage through paint needle seals
Why is my spray gun leaking at the paint needle seal?
A leak at the paint needle seal can be caused by loose or worn sealing elements. Proper maintenance and replacement of worn parts are crucial to ensure the function of the spray gun.
What can be done if there are leaks at the paint needle seal?
- Hand-tighten the needle packing: Use the SATA tool set supplied to tighten the needle packing correctly.
- Regular maintenance of sealing elements: Replace the sealing elements regularly using the SATA seal set to avoid wear.
- Replace nozzle set as needed: Worn nozzles affect performance and can cause leaks. It therefore makes sense to check them regularly.
What causes leaks at the paint needle seal?
- Inadequate tightening of the paint needle seal screw: An inadequate tightening of the screw will cause the seal to loosen and result in leaks.
- Wear of the paint needle seal: Worn seals can impair the material flow and cause leaks.
- Paint needle with dried paint residue: Paint residue on the paint needle creates friction between the paint needle and the seal, which can cause damage.
