Products Details

Malleable Iron 300 Octagonal Cap. Octagonal Cap named Hexagon cap,is a kind of stopping pipe fittings commonly used in the end of the pipeline, the function is same with the plug. Plug is with external thread but cap is with internal thread, so Hexagon cap can be called internal thread plug. The minimal size of the hexagon cap is 3/8″ that’s DN10 and the maximum size of the hexagon cap is 2″ that is DN50. Working pressure is 2.5Mpa that’s PN25.

3. Convenient maintenance: The hexagon cap can be easily removed and installed, making pipe repair and replacement simple and easy.
4. Prevent pipe damage: Hexagon caps can protect pipes from external mechanical damage and increase the service life of pipes.
5. Corrosion resistance: Hexagon cap materials have excellent corrosion resistance and can adapt to the transportation requirements of various chemical media.
6. Good aesthetic effect: Hexagon caps can hide irregular pipes and improve the aesthetics of the entire system.
