A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Common uses for diaphragm seals are to protect pressure sensors from fluid whose pressure is being measured.

Molded elastomeric diaphragms are tough, versatile dynamic seals that eliminate virtually all of the limitations associated with other sealing methods like U-cups, o-rings, metal bellows and flat die-cut diaphragms. They can withstand pressure to 6,000 Psi (4.137 bar) over a temperature range from -80°F to +500°F.
