Frequently Asked Questions
- Q: What is the difference between GI and Malleable Iron fittings?
- A: GI (Galvanized Iron) fittings are cast iron fittings coated with zinc for corrosion protection — suitable for water service. Malleable Iron fittings are heat-treated to improve ductility and shock resistance, making them stronger and better suited for higher-pressure and gas applications.
- Q: Are these fittings suitable for gas lines?
- A: Yes — Class 150 and 300 malleable iron threaded fittings to BS 143 are approved for gas distribution. For high-pressure gas lines, ASTM A105 carbon steel forged fittings to ASME B16.11 are recommended.
- Q: What sizes are available?
- A: GI and malleable iron fittings are stocked from ¼" to 4" NB. Larger sizes (4" to 8") and special configurations are available on order with 1–2 weeks lead time.
