Bronze Unthreaded Pipe Fittings
Snap a brazing ring (sold separately) into these fittings and braze them to unthreaded pipe for a strong, leak-resistant connection. Fittings are also known as Silbraze fittings. They are bronze, which is compatible with brass and has good corrosion resistance.
Union connectors separate into three pieces so you can access your line.

Brass and Bronze Unthreaded Pipe Flanges
Bolt these flanges to equipment or to another same-size, flat-surface flange with a gasket (sold separately). They have good corrosion resistance.
Socket-connect flanges braze onto unthreaded pipe with a brazing ring (sold separately) for a strong, leak-resistant connection. They are also known as Silbraze flanges.
