Diaphragm Seal & Gauge Protector

Diaphragm seals (chemical seals) and gauge protection devices mounted between the process connection and a pressure gauge or transmitter: they separate the measuring element from aggressive, hot, viscous or crystallising media, and limit overpressure. Created 10.10.2026 because 75 such items were spread across three unrelated types.
