Notes:
[1] Models have zinc-plated steel spring exposed to media.
[2] Models have 300-series stainless steel spring exposed to media.
[3] Not recommended for rapid or high cycling pressure changes.
[4] Not recommended for gas service, since drying of the O-ring can allow bleeding of the medium into the atmosphere.
