740-741 High-Displacement Diaphragm Seals
| Previous | 20 / 30 | Next |
The Ashcroft® 740 and 741 high-displacement diaphragm seals are used with low-ranged instruments or high static pressure differential pressure gauges with low differential pressure. Used to ensure material compatibility, they are also applied when process media exhibit pulsation or the potential to clog an instrument connection. An ideal product for satisfying low pressure measurement needs.
Key Features:
- Wide selection of diaphragm and lower housing materials
- Enlarged welded diaphragm; high displacement allows high sensitivity to pressure fluctuations
- Flush port (type 741) provides easy cleaning / flushing for process media prone to clogging
