Key Applications
Frequently Asked Questions
What is the difference between cast iron and bronze Y-strainers?
Cast iron Y-strainers are used for larger pipe sizes (2" and above) and lower pressure applications compared to bronze. Cast iron offers cost advantages for large diameter water and sewage lines but is not suitable for potable water with aggressive chemistry. Bronze strainers are preferred for smaller sizes where frequent handling is needed and for seawater or brine service where cast iron would corrode rapidly.
