How to Identify and Measure Fittings

Low-Pressure Aluminum
Threaded Pipe Fittings
In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.
Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.
NPTF (Dryseal) threads and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

- For Use With: Air, Oil, Water
- Class: 150
- Pipe Nipples and Pipe: Use Schedule 40 aluminum
- Flanges: Use Class 125 aluminum
