- Light industrial and workshop piping where quick assembly and dependable sealing are priorities
- Retrofits and repairs in existing systems where new elbows must mate with existing FIP threads
Installation tips for best results
- Always clean and inspect threads before assembly; ensure threads are undamaged for a proper seal
- Use appropriate pipe-thread sealant or PTFE tape on male threads to achieve a reliable seal without overtightening
- Hand-tighten first, then snug with a wrench to the recommended torque without overt stress on the fitting
- Verify alignment after installation and pressurize slowly to check for leaks before burying or concealing the run
