Volume(s): Gases
Language: English
Type: Single Standards Download (.pdf)

This Standard was technically approved by the Gases Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on May 19, 2015. Available at and in August 2015.


This Standard establishes the physical dimensions of filters, check valves, restrictors, port converters and other components for 1.125 inch type surface mount gas distribution systems.


This Standard applies to components that are installed in between a substrate and a component in a sandwich or stacked manner.


This Standard establishes standard dimensions to provide interchangeability for components of equivalent function.


This Standard applies to two and four fastener configurations.


This Standard only applies to components for systems which control flow of ≤50 slm nitrogen equivalent at 308 kPa (44.7 psia).


This Standard only applies to components with operating pressures less than 3445 kPa (500 psia) at 20°C.
