Product Description

Glass-Trac Welding Pad Gauges are used when standard tank connections cannot be used or when the liquid has solids in suspe
nsion. The gauge becomes an integral part of the vessel because it is welded right onto the outer wall. Reflex or Transparent glass is used in any of nine standard lengths. Standard covers are 3⅛” wide.

Notes: Welding pad gauges to be used on vessels less than 36” in diameter must be special ordered. The welding pad body must be machined to allow proper fit up. When ordering, add WP to gauge size number.
