Dockglass Spar Emergency Breather Transit Pattern

Dockglass Spar Emergency Breather Transit Pattern is a last-air set for crossing a dead compartment or keeping a casualty conscious until the patch holds. The build combines aramid weave, titanium hardware, fluorosilicone seals, and vacuum-rated aerogel; this dockglass version adds clear inspection windows over every loaded seal. Spar parts are long, stiff, and easy to brace against a hull. Transit stowage is flat enough for a locker beside the lock. The bottle rides flat against the chest, feeding a hood or suit bypass through a keyed hose that cannot be mated backward. A mechanical gauge remains legible after the battery dies, and the purge lever is broad enough for numb gloves. Regulator ice starts as a hiss and ends with an empty cylinder. Warm it with a gloved hand—never an exposed heater.
