High-Pressure Brass Threaded Pipe Fittings
These fittings have the strength to handle high-pressure applications. They are brass for good corrosion resistance.
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through a wall or panel to create an inlet or outlet.
Female x male 90° elbow adapters are also known as street elbows.
Inline tees are also known as branch tees. NPTF (Dryseal) threads are compatible with NPT threads.
