To meet your casing insulator and end seal needs, Topaz offers a variety of materials, styles, and carrier-casing size differentials. Economy, required method and ease of installation, standard or special carrier-casing configurations, single or multiple carrier lines, and fireproof versus non-fireproof construction are but a few of the considerations which can be addressed.

Lightweight molded polyethylene insulators are supplied for 3/4" through 48" diameter and larger carrier lines. Heavy-duty steel insulators are supplied in the same sizes with insulating glass reinforced plastic runners, or non-insulating steel runners.

Casing end seals are supplied in a standard pull-on style for all popular carrier-casing combinations, a custom pull-on for unusual combinations or excessive lateral movement, standard wrap-around style for existing crossings where the carrier line is already welded, and a fireproof wrap-around style for installations in fire prone areas.
