103-612 Siphon Tube is a genuine OEM replacement siphon tube for Titan airless sprayers. The siphon tube draws coating material from the container up into the pump inlet, ensuring a steady supply of fluid during operation. A cracked, clogged, or damaged siphon tube can cause loss of prime, air ingestion, and intermittent spraying. Replacing the siphon tube restores proper fluid pickup and reliable spray performance.

The Titan 103-612 Siphon Tube is the rigid or semi‑rigid tube that extends from the pump inlet down into the coating container. Its purpose is to draw material upward into the pump foot valve, ensuring a continuous supply of coating during spraying. The siphon tube is typically made of chemical‑resistant metal or plastic and includes a fitting for secure attachment to the pump housing.
Over time, siphon tubes can become cracked (allowing air ingestion), clogged with dried coating or debris, or bent from mishandling. A damaged siphon tube causes difficulty priming, loss of prime during operation, spitting, or reduced flow. Replacing the siphon tube with an OEM component restores proper material pickup and eliminates air leaks.

|---|---|
| Air sealing | Prevents air from being sucked into the fluid system |
| Flow path | Provides a clear channel for material to reach the foot valve |
| Loss of prime / difficulty priming | Sprayer struggles to draw material or loses prime quickly |
|---|---|
| Visible cracks or holes | Cracks in tube allow air to enter, causing spitting |
| Clogged tube | Dried coating or debris blocks the tube |
| Bent / kinked tube | Tube deformed, restricting flow |
