Frequently Asked Questions

Not necessarily. Graco lists several 1/4 NPT nipples with different lengths or materials. Use 100124 when that exact part number appears in your model’s parts diagram (e.g., King™ Sprayers or the 10:1 Standard Pump assemblies).

Check your equipment’s parts manual. If the bill of materials calls out 100124 for a 1/4 NPT nipple (2.5"), it’s the correct drop-in. If a different length/part is listed, match that number instead.

Yes—follow Graco guidance for NPT thread sealant on metal-to-metal pipe threads. Apply sparingly, avoid excess, and do not contaminate fluid paths.

Avoid length substitutions unless your assembly provides clearance and alignment. Many Graco systems rely on the specified 2.5" length for proper spacing and support.

It’s commonly found between regulators, valves, filters, or manifolds in Graco pump assemblies such as King™ Sprayers and the 10:1 Ratio Standard Pump systems.
