Diaphragm Seals / Capillaries, Gauges

Description - AMETEK’s XR-Series All-welded Gauge and Seal offers customers a lower cost alternative to an individual gauge and diaphragm seal with the added benefit of a reduction in potential leaks and double containment.

The high quality, rugged SOLFRUNT 1981 (SST internals) or the SOLFRUNT 1986 (Monel internals) gauge is mounted and welded onto the M&G XR diaphragm seal. XR-Series all-welded systems are compliant to NACE MR-01-03 and MR-01-75 requirements. The designed operating pressure is 3000 psi at 100°F and has a maximum static pressure rating of 5000 psi.

The standard XR diaphragm seal has a 4:1 safety ratio and is available with either 316L SST or Monel wetted parts, and has an 1/2” NPT male, 1/4” male, 1/2” female, or 1/4” female bottom for the process connection. Other connections and materials are available, such as Hastelloy® C body and diaphragm or Tantalum diaphragm.
