Frequently Asked Questions
This fitting creates a three‑way junction, allowing fluid or air to flow from one line into two outlets (or join two into one). It’s common in manifolds where routing or branching is needed.
Not all Graco sprayers use this tee. It’s specific to models and assemblies that include a three‑way fluid/air junction in their parts diagram — such as MP300, MP400 and Mustang 4800.
Thread sealant or NPT tape is recommended on threaded connections to ensure a leak‑free installation.
