702-703 Flanged High Displacement Diaphragm Seals

The Ashcroft^® 702 and 703 high-displacement diaphragm seals are used with low differential pressure gauges rated for elevated static pressures up to 750 psi. 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
• Flushing port (type 703) provides easy cleaning / flushing due to process media prone to clogging
