SLN13102110_REV2_12122024.pdf

This is a technical specification drawing detailing the design of oxygen regulators for advanced EVA spacesuits. The drawing shows multiple views (-601 and -602 reference views) of oxygen regulator components, including primary/secondary inlet ports, outlet ports, and refill ports, along with detailed cross-sections, dimensions, and technical specifications.

The drawing set (document number D21356, SLN13102110) appears to be part of NASA's Advanced EVA Regulator program for EVA O2 regulators. Multiple pages show detailed engineering specifications including precise measurements, cross-sectional views (Sections A-A, B-B, C-C), and specific details (Detail D and E) of the regulator assembly. The drawings include both isometric reference views and detailed dimensional specifications needed for manufacturing these critical life support components. Flag notes indicate requirements for weld depths and general fabrication guidance.
