Light Pattern Fittings Explained
Features and Material Grades
Light pattern fittings offer a cost-effective solution for systems with lower pressure requirements. You will find these fittings use thinner walls and less material than heavy pattern fittings. This design makes them lighter and easier to handle during installation. Manufacturers often use stainless steel grades like 304 and 316 for these fittings, which provide good corrosion resistance for most environments. You benefit from a simple, straightforward fitting that works well in non-critical applications.
Typical Uses
You should choose light pattern fittings for residential plumbing, irrigation, and other light-duty systems. These fittings work best in places where high pressure is not a concern. Many contractors use them in water supply lines, HVAC systems, and general plumbing projects. You can also find them in some commercial settings where the system does not require strict compliance or high-pressure resistance.
Tip: Light pattern fittings help you save on material and installation costs when your application does not demand heavy-duty performance.
Limitations and Considerations
Light pattern fittings have limitations in pressure rating and compliance. You should not use them in critical or high-pressure industrial systems. Regulated industries often require fittings that meet strict standards. Light pattern fittings may not always comply with these requirements.
Here is a table showing common compliance issues you might encounter with light pattern fittings in regulated industries:
| Compliance Issue | Description |
|---|---|
| Dark-sky ordinances | Regulations that limit upward light spill and glare to minimize environmental impact. |
