  • Designed to isolate the pressure measuring instrument from high temperatures, or corrosive or viscous process media
  • Can be used for remote mounting of pressure instrument(s) with capillary, see options & accessories below
  • Utilizes a replaceable diaphragm clamped between the flanged metal housings with an o-ring seal to create a leak-free union
  • Process connection sizes from 1/4" NPT through 1-1/2" NPT
  • Flushing port connection is an available option that allows the wetted areas of the seal to be cleaned, or the process vented without removing the unit from the line
  • Consider instrument size, pressure range, media composition, ambient and operating temperature, and maximum working pressure when selecting
  • Capillaries and cooling elements are available for elevated process temperatures, see options & accessories below
  • Fill fluid must be compatible with process media; i.e. Glycerin may become volatile in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or peroxide and nitric acids

Distribution Manifolds

NOSHOK's Distribution Manifolds connect multiple instruments to one diaphragm seal, eliminating multiple connections that lead to possible leak paths.

Plain & Armored Capillaries

  • 5 ft. SS Armored Flexible Capillary, 1/4" NPT (AC-02-02-5) per ft. adder (AC-02-02-#)
  • 5 ft. SS Armored Flexible Capillary, 1/2" NPT (AC-04-04-5) per ft. adder (AC-04-04-#)
  • Stainless Steel capillaries available with or without Stainless Steel armor
  • Protects the instrument from high or low process temperatures
  • Allows remote mounting of pressure instrument(s)
  • Select the shortest capillary length possible, as changes in ambient temperature conditions may significantly affect the accuracy and response time of the instrument
  • Standard length 5', others available
  • Installation on analog gauges requires a gauge support and gauge adaptor, or other surface mounting provisions
  • Any level difference between the instrument and the seal will result in a pressure indication error; make sure to compensate for the level difference during calibration of the diaphragm seal assembly if the level difference is known
  • Filling options for capillaries
    • Silicone - specify to 10 or 20 feet (SL-C)
    • Halocarbon® - specify to 10 or 20 feet (HL-C)
