FAQs

1. What type of marine strainer do I need for my system?

Choose based on application: bronze intake strainers for engine cooling, inline clear‑bowl strainers for pumps, and universal mesh strainers for general plumbing protection.

2. What mesh size is best for raw‑water filtration?

Most marine systems use 40–50 mesh for pump protection, while 20 mesh is suitable for higher‑flow applications where larger debris is the primary concern.

3. How often should marine strainer baskets be cleaned or replaced?

Inspect baskets every trip in debris‑heavy waters and clean as needed. Replace screens or baskets when damaged, corroded, or showing reduced flow.
