The U-SEAL™ Casing Seal allows maximum flexibility for carrier pipe movement and concentric installations. The Z-SEAL™ Casing Seal is a thick, heavy-duty casing seal for installations where an extra rugged seal is desired.

Standard Centering Cradles are used to center the pipe in the end of the casing, making it easy to install TDW Z-SEAL™ Casing Seal. The cradles also carry the weight of backfill dirt and insulate the pipe from the casing. They are recommended for use with TDW Concentric Support Insulators. Nonconcentric 3-Way Cradles restrain pipe in all directions. They are used with U SEAL™ Casing Seals.

The M-2 Plastic THINSULATOR® pipe insulator is a high-density, polyethylene product, injection molded to provide low cost insulators of highest quality. This high-density polyethylene gives the M-2 such strength that it is made more compact than other insulators.
