The Graco 164856 Reducing Nipple Fitting adapts a 3/8″ NPT port to a 1/4″ NPT connection for high-pressure fluid systems. Ideal for ensuring proper size transitions in industrial spray setups.
This part appears in Graco industrial sprayer packages and pump systems that step down a 3/8″ NPT port to a 1/4″ NPT connection. Always confirm against your unit’s parts manual.
Graco 164856 is a reducing nipple fitting used to adapt different NPT thread sizes in high-pressure fluid systems, commonly found on industrial sprayer packages and pump assemblies.
| Specification | Detail |
|---|---|
| Part Number | 164856 |
| Type | Fitting, Nipple, Reducing |
| Thread Size | 3/8″ NPT × 1/4″ NPT (male × male) |
| Application | Adapts a 3/8″ NPT port to a 1/4″ NPT connection in the fluid path |
| Typical Use Cases | Connecting pumps, manifolds, or hose/rigid line transitions where size reduction is specified |
| Fitment Reminder | Match the machine’s schematic/parts manual; do not substitute if different sizes are specified |
This reducing nipple provides a secure, pressure-rated transition between 3/8″ NPT and 1/4″ NPT male ends. Because it is a general adaptor used across multiple assemblies, compatibility depends on whether your specific model’s fluid circuit calls for this exact reducer at the location in question.
