The SprayTech 0277509 Fluid Tube Fitting is a precision‑machined connector used in HVLP Maxum II spray guns to join the fluid pickup tube to the gun body. It creates a secure, leak‑tight seal that ensures consistent paint delivery from the cup to the nozzle.
This fitting is engineered to withstand the repeated connection cycles and solvent exposure common in professional finishing environments. A properly seated fluid tube fitting prevents air from entering the fluid stream, which can cause spitting, sputtering, and uneven spray patterns. Over time, fittings can become worn, cracked, or have damaged threads, leading to leaks and performance issues. Replacing a faulty fitting restores reliable fluid flow and ensures a smooth, professional finish.
