JIANZHI Black Iron Pipe Cap

Jianzhi brand 300 black hex cap is for closing the end of female threaded pipe fittings. 

Pipe caps connect with female pipes or fittings and connects with threads, which create a tighter seal than straight threads. The hexagon allows for increased leverage and uses a wrench during installation and disassembly.

We can make different kinds of threads according to different standards, such as NPT, ISO228, ISO7-1, BSPT, BSPP.

Hex caps usually are expensive than rough caps, but it is much easier to assemble.

The smallest size of Jianzhi Hex caps is 3/8'', the largest size is 2'', with better resistance to corrosion.
