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.
Female x male 90° elbow adapters are also known as street elbows.

Medium-Pressure Aluminum Threaded Pipe Fittings
Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings. They are lightweight with good corrosion resistance.
Fittings with blue anodized finish have better corrosion resistance and a harder surface than plain aluminum fittings.
Female x male 90° elbow adapters are also known as street elbows.
