1. A bulkhead igniter assembly comprising:
a bulkhead igniter having a first end and a second end, wherein the first end of the bulkhead igniter is formed with at least one ridge or groove on an annular protrusion;
a pressure block having a first end and a second end, wherein the bulkhead igniter is disposed within a cavity of the pressure block;
a setting tool having a first end and a second end, wherein the pressure block is at least partially disposed within a cavity of the setting tool located proximate to the first end of the setting tool; and
a snap-on insulator, wherein the snap-on insulator comprises:
an annular body having a tubular channel through a center portion,
wherein, the snap-on insulator has a first end and a second end,
wherein, an interior of the tubular channel is formed with a ridge or a groove that is sized and configured to be a complimentary member to the ridge or groove on the first end of the bulkhead igniter, whereby the snap-on insulator is held in place on the bulkhead igniter by interaction of the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter,
wherein, the snap-on insulator is formed from a material that allows for enough flexibility for a ridge-and-groove coupling to occur so that the snap-on insulator may be installed onto the bulkhead igniter by pressing the snap-on insulator onto the bulkhead igniter to engage the ridge or groove of the snap-on insulator with the ridge or groove of the first end of the bulkhead igniter; and
wherein, the snap-on insulator is formed from a material that will not conduct electricity.
