CPVC bulkhead fittings are corrosion-resistant connectors that seal piping through tank walls using internal and external threads. They are offered in sizes from 1/4" to 8", with both short and long shaft styles, reinforced threads, and oversized flanges. Ideal for chemical storage, process vessels, water treatment and industrial systems, these fittings provide leak integrity, chemical compatibility and robust construction for reliable, long-term operation.
