Cooling Elements
  • 1/4" NPT x 1/4" NPT Cooling Element (1/4" NPT x 1/4" NPT-CE)
  • 1/2" NPT x 1/2" NPT Cooling Element (1/2" NPT x 1/2" NPT-CE)
  • Works in combination with diaphragm seal to isolate instrument from high media temperatures
  • Recommended for process temperatures above 212 ºF
  • Requires direct mounted system
  • Effective temperature reductions of 200 ºF depending upon ambient conditions
  • High >212 °F process temperature, low < -40 ºF process temperature
  • All Stainless Steel construction
Diaphragm Seal Fill Options
  • Glycerin (GY) Not recommended for use in vacuum applications.)
  • Silicone (SL)
  • Halocarbon® (HL)
  • Neobee M20 (NB)
  • Mineral Oil (MO)
  • Propylene Glycol (PG)
Distribution Manifolds
NOSHOK's Distribution Manifolds connect multiple instruments to one diaphragm seal, eliminating multiple connections that lead to possible leak paths.
Plain and 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)
