Well yeah, it's just what it says it is.  This burst disc has a very short head above the threads so it doen't extend out away from the regulator. This more compact design makes for a sleeker look and a little less weight which is always a good thing.

This particular version is rated at 1800psi / 1.8k psi.  It's clearly marked on the top so you know exactly what you're working with.  The standard 3/8-24 threads make it a perfect replacement for other burst discs of the same rating.

As always, this Ninja product is Made In The USA and the 1 piece unified design conforms to all relevant safety specifications.
