Caustic Media–Shielding Seals

Types 510 and 511 diaphragm seals are the newest addition to Ashcroft’s line of instrument media isolators. These economical, all-welded seals protect pressure gauges, transmitters, switches, and other instruments against the potentially harmful effects of caustic media. The seals are available for use with ranges from vacuum through 5,000 psi, and they can be threaded onto any ½ NPT fitting or welded directly to eliminate the possibility of leakage. Other features include a choice of diaphragm materials, fill fluids, and a lower housing flush port (Type 511). (http://www.ashcroft.com)
