AirCraft Valve Needle Kit (Parts 26, 35–39) for SG AC2000 Viper Series

AirCraft Valve Needle Kit (Parts 26, 35–39) for SG AC2000 Viper Series (SG AC2000-SK05)

Restore Smooth Fluid Control and Clean Shut-Off

The AirCraft SG AC2000-SK05 Valve Needle Kit is a replacement service kit designed for AirCraft Viper Series SG AC2000 spray guns. If your spray gun is dripping, failing to shut off cleanly, or the trigger action feels rough and inconsistent, worn needle and valve components are often the cause.

This kit replaces parts 26 and 35–39 in the SG AC2000 assembly, restoring proper needle sealing, smooth movement, and reliable fluid control for more consistent spraying performance.

Why Replace the Valve Needle Components?

Over time, paint residue, wear, and deteriorated seals can affect the needle and valve assembly, leading to:

• Paint drips and leakage

• Poor fluid shut-off

• Sticky or rough trigger action

• Inconsistent paint flow

• Reduced spray finish quality

Replacing these service components helps restore factory-level performance without replacing the entire spray gun.

Maintenance Tips

• Keep the needle and packing area clean to prevent drag and leakage caused by dried paint.

• If spray patterns remain uneven after servicing, inspect the nozzle and air cap for wear or damage.

Pro Tip

After installation, adjust the needle packing carefully. Overtightening can cause the needle to stick, while a loose adjustment may allow leaks. Aim for smooth needle movement with no seepage before locking the adjustment in place.

Safety Information

• Disconnect the spray gun from the air supply before servicing.

• Wear appropriate eye protection when handling solvents and small components.

• Use cleaning solvents and thinners in a well-ventilated area away from flames or sparks.

• After reassembly, test spray at low pressure to confirm proper shut-off and safe operation.
