WELDED MINI-SEALS

REOTEMP Welded Mini Seals are ideal for applications where a gauge or general purpose transmitter cannot be installed directly into the process media. REOTEMP mini seals are a one-piece, all-welded construction that offer a durable, economical choice for protecting a pressure instrument from corrosion, clogging, or high process temperatures.

  • Economical Choice for Protecting a Pressure Instrument from Severe Process Media
  • All-welded Design Reduces Fugitive Emission Leaks
  • Available with PulsePlus™ Pulsation Dampening
  • Tamper Resistant
