Diaphragm Seal – Welded Mini-Seals

Description

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
