WELDED MINI-SEALS
Welded Mini Seals are ideal for applications where a gauge or general purpose transmitter cannot be installed directly into the process media. 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
