Extreme-Pressure Brass Threaded Pipe Fittings
Extreme pressures are no problem for these heavy-duty fittings. They are brass for good corrosion resistance.
Female x male 90° elbow adapters are also known as street elbows.
Inline tees are also known as branch tees. Right-angle tees are also known as run tees.
NPTF (Dryseal) threads are compatible with NPT threads.
