Titan 103-833 Siphon Hose Assembly

Siphon Hose Assembly (103-833) for PowrLiner Series

The 103-833 siphon hose assembly is a critical component of the material delivery system on PowrLiner 6950_1, 6950, and 4950 airless sprayers. Its primary function is to draw paint, stain, or other coatings from the supply container and deliver it to the pump inlet. Unlike a simple length of hose, this assembly is specifically engineered for reliable priming and continuous operation. It typically includes a weighted pickup end that keeps the hose submerged as the fluid level drops, preventing air from being drawn into the system. The hose material is selected for flexibility, chemical resistance, and the ability to maintain its shape without collapsing under suction.

In professional painting applications, the siphon hose is subjected to continuous flexing, exposure to solvents, and potential abrasion from container edges. Over time, the hose can develop cracks or pinholes that allow air to enter the system, causing the pump to lose prime and spray patterns to become erratic. The hose may collapse internally if its structure weakens, restricting flow and starving the pump. The weighted end can become dislodged or corroded, failing to keep the hose properly positioned. Any of these conditions leads to downtime, wasted material, and frustration for the operator. The 103-833 siphon hose assembly is manufactured to exact original specifications, using materials that resist the harsh chemicals found in professional coatings and maintain flexibility across a wide temperature range.

Replacing a worn or damaged siphon hose with the 103-833 assembly restores reliable material pickup and priming performance. Installation is straightforward, typically involving attachment to the pump inlet fitting and ensuring the weighted end is free to move within the container. It is important to select the correct hose length for the application, as an excessively long hose can coil and kink, while a short hose may not reach the bottom of larger containers. The new hose should be inspected for any shipping kinks before installation, and the pickup end should be checked for secure attachment. With a properly functioning siphon hose assembly, the sprayer primes quickly and maintains consistent material flow, allowing the operator to focus on the task at hand rather than troubleshooting feed problems. For PowrLiner owners, maintaining the siphon hose in good condition is essential for efficient operation and professional results.
