The Hexagon Cap Fig.300 is a threaded pipe fitting used to seal the end of a pipe in gas and water supply systems. Made from malleable iron and finished with a galvanized coating, this cap provides long-term corrosion resistance and secure sealing — either permanent or temporary — across industrial and residential systems.

Why Choose Jianzhi Hexagon Cap?
Using cast iron threaded fittings helps protect the entire pipeline from leaks, pressure loss, or breakage — not just at the joints, but across the full system. Jianzhi produces hex caps that meet international standards and certifications.
