Practical Use Cases

This 45° adapter is especially useful when:

• You need to reroute fluid lines in tight spaces
• The standard straight fitting would interfere with other components
• You are installing or servicing Graco pumps where the port layout makes straight connectors impractical

Installation Tips

• Ensure mating threads (JIC and NPT) are clean and free of debris.
• Use appropriate thread sealant or tape on the NPT side for leak prevention.
• Tighten carefully — over-torquing may distort sealing surfaces or damage flared connections.
• Inspect for leaks after pressurizing; re-tighten or replace if needed.
