104 In-Line Threaded Diaphragm Seals
- Certificates & Approvals
The Ashcroft® 104 in-line diaphragm seal or isolation device protects pressure measuring instruments. Mounted in-line to the process piping, it is used on applications where continuous flow prevents process clogging or accumulation, while preventing process fluid loss in the event the measuring instrument is removed or fails. An ideal choice for satisfying challenging installation requirements.
- Wide selection of diaphragm and lower housing materials
- Diaphragm threaded to top housing
- Process size: 1/4" and 1/2" NPT
- Rated up to 2500 psi
