Installation & Fit‑Up Tips
- Confirm your machine’s **parts list** to ensure 112538 is correct for your model and serial number.
- Check that the male/female threading matches what the elbow will connect to (e.g., 1/8 NPT(f) to 1/4 NPT(m) in some cases).
- Ensure threads and sealing surfaces are clean, undamaged and properly sealed (use correct sealant or tape if required).
- Install when system is depressurized to avoid risk of fluid/air release.
- After installation, check for leaks and ensure the elbow orientation allows proper routing (avoid undue stress or sharp bends).
Frequently Asked Questions
A “street” elbow means the fitting has one **male thread** and one **female thread**, allowing it to connect directly to a female‑ and male‑threaded counterpart without an additional adapter.
Not necessarily. While the 112538 is used in certain Graco assemblies, you must verify your **specific model and serial number** parts list to ensure compatibility. Thread sizes, material and pressure ratings may differ between machines.
Before installation you should:
• Confirm the existing fitting is identical in thread type and size.
• Ensure system is depressurized.
• Remove any old sealant and clean threads.
• Use the correct thread sealant or tape suitable for your fluid or air application.
• Install the elbow with correct orientation and inspect for leaks after startup.
For further assistance or to confirm compatibility, refer to your machine’s service manual or contact your local Graco authorised distributor.
