Graco 111928 Fitting Tee Male Branch

Product Overview – FITTING, TEE, MALE BRANCH (Part # 111928)

The Graco part number 111928 is a precision‑engineered fluid‑fitting: a tee with a male‑threaded branch suitable for splitting or diverting fluid or air flow within Graco equipment systems. It is designed for use where a male‑branch connection is required to feed two downstream lines (or one upstream line splitting into two). According to the manufacturer listing it weighs approximately 0.31 lbs and its dimensions are ~0.9″ × 1.7″ × 2.05″. :contentReference[oaicite:1]{index=1}

This fitting is a genuine OEM Graco replacement part, ensuring reliable thread engagement, chemical compatibility, and pressure handling when used in approved machines.

Compatible Machines

This part is broadly listed as a standard Graco fitting used across many of their high‑pressure spray, proportioning and fluid delivery systems. While the manufacturer does *not* publish a complete machine‑by‑machine compatibility list for 111928, you can safely assume compatibility when your machine uses Graco fluid fittings with male‑threaded tee branches and the same thread size/specification. Below are examples of machines within the Graco ecosystem in which such fittings are commonly used:

• Graco GMAX II 3900 ProContractor Series (Part # 17E828) :contentReference[oaicite:2]{index=2}
• Graco GH 200 Convertible ProContractor Series (Part # 24W928) :contentReference[oaicite:3]{index=3}
• Graco GH 230 Convertible ProContractor Series (Part # 24W933) :contentReference[oaicite:4]{index=4}

If your machine is one of these, or another model from Graco’s high‑pressure airless/proportioning range, and uses tee fittings with male branches, part #111928 is likely to be compatible. Always verify by checking your machine’s parts manual or the fitting’s dimensions and thread type.

Key Features & Benefits

Installation & Usage Tips

• Verify thread type and size on your machine’s fluid manifold before installation. Just because the tee is male‑threaded doesn’t guarantee it’s the correct diameter or pitch for your machine.
• Use appropriate thread sealant compatible with your coating materials and Graco’s wetted‑parts guidelines (check chemical compatibility). :contentReference[oaicite:7]{index=7}
• Ensure operating pressure of your machine does not exceed the rated pressure of the fitting – while Graco parts are rugged, misuse at extreme pressures or with incompatible fluids may lead to failure.
• Clean and inspect the fitting when conducting maintenance intervals — ensure no debris, corrosion or thread damage before reinstalling.
