100 Series Threaded Capsule Diaphragm Seal
Brand: Ashcroft Inc.The Ashcroft 100 threaded diaphragm seals or isolation devices protect pressure measuring instruments.
Used when process compatibility is required, these are also applied when media exhibits high temperature or the potential to clog an instrument connection.
Ideal for satisfying many challenging applications.
Features- The top housing and diaphragm capsule are interchangeable with all Ashcroft bottom housing
- A fill/bleed connection is standard, which permits filling the seal and instrument simultaneously after evacuation and allows the fill to flow into the completed unit
- A viton o-ring, compatible with all standard fill fluids, and a Teflon back-up ring provide a seal between the diaphragm capsule and the top housing
- A thin Teflon PTFE gasket between the diaphragm and bottom housing ensures a leak-tight corrosion resistant seal even at high pressure
- Top housing and pressure instrument are removable
- Continuous-duty design will prevent loss of process fluid if pressure instrument is removed or fails
