Part number 700-211 is a syphon tube designed for Epic and PowrLiner series airless sprayers. This tube draws paint from the container into the pump and includes a sealing O‑ring to prevent air leaks. A cracked, clogged, or missing syphon tube can cause priming difficulties, pressure loss, or erratic spray. Replacing it restores proper fluid pickup and reliable performance.

The 700‑211 syphon tube is a vital component that carries paint from the container to the pump on compatible Epic and PowrLiner airless sprayers. It includes a precision O‑ring that seals the connection to the pump inlet, ensuring a continuous, air‑free flow of material.
Over time, syphon tubes can become brittle, cracked, or clogged with dried paint. The O‑ring may also compress, harden, or become damaged, allowing air to enter the system and causing loss of prime, sputtering, or reduced pressure. Replacing the complete tube with its integrated O‑ring using genuine 700‑211 restores a tight seal and reliable fluid pickup, minimizing downtime on the job.
