Material choice is the quickest way to make a pipe-fitting offer more useful to a buyer. Brass, stainless steel and PPR each fit a different installation logic, so a clear comparison saves time during specification.
When brass is the practical option
Brass is widely used for threaded transitions, compact valves and fixture connections. Consider a brass female threaded straight coupling when the pipe line meets threaded valves or fittings.
Where SUS304 adds value
SUS304 is suited to durable press-fit applications where corrosion resistance and a clean system finish matter. See the SUS304 stainless steel equal tee for a branching example.
Why PPR remains a common choice
PPR is economical and widely used for hot- and cold-water systems that use heat fusion. A PPR 90-degree elbow is a core fitting in that system.
Specify the whole connection, not only the material
Confirm pressure class, temperature, size, thread standard and installation method. Our pipe fittings and connectors page provides a starting point for a mixed-material programme.
