Installation and care tips
For a reliable seal on FIP connections, use appropriate pipe-thread sealant or Teflon tape compatible with iron pipe threads. Ensure mating fittings are clean and properly aligned before tightening. While the ends are threaded for easy connection, verify that you’re pairing with 3/4 in. male fittings or valves to achieve a secure, leak-free connection. Periodically inspect the connector for signs of wear, particularly in high-traffic or high-use areas, and replace if any corrosion or damage appears.
