A frangible plug for use in a valve mechanism, the frangible plug comprising:
- a first section having a first end and an opposing second section having a second end and a cylindrical sidewall extending between the first and second ends;
- means for applying a force on the cylindrical sidewall of the frangible plug such that the first section fractures from the opposing second section, and wherein the means for applying a force on said cylindrical sidewall extends circumferentially around the outer circumference of the sidewall.
A valve mechanism comprising:
- a valve body having an inlet port and an outlet port and a passageway extending therebetween;
- and
- a frangible plug as claimed in any preceding claim, wherein the plug is held within the valve body such that the plug blocks the passageway when intact and wherein, when the frangible plug is fractured, fluid flows from the inlet port to the outlet port.
