Graco 117594 Fitting Straight 3/8″ NPT × 1/2″ T Overview
The Graco 117594 Straight Fitting (3/8″ NPT × 1/2″ T) is a compact, high‑quality connector designed for threaded fluid‑system integration in Graco sprayers.
- Connection Sizes: 3/8″ NPT male × 1/2″ T female.
- Style: Straight adapter/fitting for fluid system use.
- Typical Use: Inline or threaded connection in spray machines’ fluid delivery subsystems.
Design & Materials
This fitting uses standard NPT threading for secure, leak‑resistant connections. Built compact for minimal spatial footprint and optimized for industrial coating equipment.
Performance & Specifications
With a length of approximately 0.9 in and width of ~1.6 in, it supports precise installation in confined spray‑system assemblies.
Installation & Maintenance
Ensure threads are clean and properly sealed (e.g., PTFE tape recommended), avoid over‑torqueing. Inspect periodically for leaks or thread damage, especially when used with high‑pressure coatings systems.
System Integration Notes
Because the fitting uses a 3/8″ NPT inlet, confirm compatibility with the machine’s existing port. Thread adapters should match or be rated for the same working pressure and fluid media.
Frequently Asked Questions
The “3/8″ NPT” refers to the male National Pipe Thread inlet size; the “1/2″ T” indicates a female‑threaded port sized at 1/2″. Together they define how this adapter connects within the fluid system.
Yes — it is designed for use in industrial spray machines from Graco, which operate at elevated pressures. Always verify that the system pressure rating of the machine does not exceed the fitting’s specification.
Yes, provided it is in good condition (no thread damage, no corrosion) and the new machine port matches the size and threading. Ensure clean threads and correct sealing for best performance.
