A high-pressure passthrough having a penetrator body is connected to a protective suit, wherein a first half of the penetrator body is positioned exterior of the protective suit and a second half of the penetrator body is positioned interior of the suit. A high-pressure passthrough valve is positioned on the second half of the penetrator body, wherein high-pressured air is supplied to an interior space of the protective suit. Releasing the quantity of high-pressure air to the interior of the protective suit with the high-pressure passthrough valve may act to cool the interior of the protective suit. ## Claims ### Claim 1 A high-pressure passthrough apparatus comprising: a penetrator body connectable to a chemical suit, wherein the penetrator body comprises a first half positionable on an exterior side of the chemical suit and a second half positionable on an interior side of the chemical suit when the penetrator body is connected to the chemical suit; a high-pressure inlet positioned on the first half of the penetrator body receiving high pressure gas from a high pressure source; a high-pressure self-contained breathing apparatus (SCBA) outlet positioned on the second half of the penetrator body receiving air from the high-pressure inlet and supplying air to a head portion of the chemical suit; and a high-pressure passthrough valve positioned on the second half of the penetrator body within an interior space of the suit and receiving high pressure gas from the high-pressure inlet, wherein high pressure gas is supplied to the interior space of the chemical suit through the high-pressure passthrough valve, and wherein the high-pressure passthrough valve further comprises a service pressure range of between 900 PSI and 6,500 PSI. ### Claim 2 (depends on 1) The high-pressure passthrough apparatus of claim 1, further comprising a hermetically sealed engagement between the first and second halves, wherein the hermetically sealed engagement comprises a raised boss on at least one of the first and second halves. ### Claim 3 (depends on 1) The high-pressure passthrough apparatus of claim 1, further comprising at least one O-ring positioned between the first and second halves. ### Claim 4 (depends on 1) The high-pressure passthrough apparatus of claim 1, further comprising at least one threaded connector removably engaged between the first and second halves. ### Claim 5 (depends on 1) The high-pressure passthrough apparatus of claim 1, wherein the penetrator body further comprises a surface treatment, the surface treatment being at least one of: a hard coat anodizing and polytetrafluoroethylene flash-coating. ### Claim 6 (depends on 1) The high-pressure passthrough apparatus of claim 1, wherein the high-pressure passthrough valve releases a quantity of high-pressure air into the interior space of the chemical suit when the penetrator body is connected to the chemical suit. ### Claim 7 A protective suit having a high-pressure passthrough comprising: a protective suit; a high-pressure passthrough having a penetrator body connected to the protective suit, wherein a first half of the penetrator body is positioned exterior of the protective suit and receives high pressure gas from a high pressure source, and a second half of the penetrator body is positioned interior of the protective suit; a high-pressure self-contained breathing apparatus (SCBA) outlet positioned on the second half of the penetrator body and receiving air from the first half of the penetrator body and supplying air to a head portion of the protective suit; and a high-pressure passthrough valve positioned on the second half of the penetrator body within an interior space of the protective suit, wherein high-pressured air is supplied to the interior space of the protective suit through the high-pressure passthrough valve, and wherein the high-pressure passthrough valve further comprises a service pressure range of between 900 PSI and 6,500 PSI. ### Claim 8 (depends on 7) The protective suit of claim 7, wherein the protective suit further comprises a chemical protective suit. ### Claim 9 (depends on 7) The protective suit of claim 7, further comprising a hermetically sealed engagement between the first and second halves, wherein the hermetically sealed engagement comprises a raised boss on at least one of the first and second halves. ### Claim 10 (depends on 9) The protective suit of claim 9, further comprising at least one O-ring positioned between the first and second halves. ### Claim 11 (depends on 7) The protective suit of claim 7, further comprising at least one threaded connector removably engaged between the first and second halves. ### Claim 12 A method of supplying a quantity of high-pressure air to an interior of a chemical protective suit, the method comprising: supplying a quantity of high-pressure air from a high pressure source to a first half of a high-pressure passthrough positioned on an exterior of a chemical protective suit; receiving said quantity of high-pressure air from said first side of said high-pressure passthrough at a second half of said high-pressure passthrough positioned on an interior of said chemical protective suit; releasing at least a first portion of the quantity of high-pressure air to a self-contained breathing apparatus (SCBA) outlet positioned on said second half of said high-pressure passthrough and supplying said first portion to a head portion of the chemical protective suit; and releasing at least a second portion of the quantity of high-pressure air to an interior space of the chemical protective suit with a high-pressure passthrough valve, wherein the high-pressure passthrough valve further comprises a service pressure range of between 900 PSI and 6,500 PSI. ### Claim 13 (depends on 12) The method of claim 12, wherein releasing the portion of the quantity of high-pres sure air to the interior of the chemical protective suit with the high-pressure passthrough valve cools the interior of the chemical protective suit. ### Claim 14 (depends on 12) The method of claim 12, wherein the quantity of high-pressure air released to the interior of the chemical protective suit with the high-pressure passthrough valve further comprises a quantity of air compressed above atmospheric air pressure.
