Zsi Cush‑A‑Therm 3/8″ Hole Seal, 3/4″ Insulation, Pack of 10

The Zsi Cush‑A‑Therm seal provides a crush‑resistant, airtight barrier for chilled refrigeration lines and mechanical pipelines that demand continuous insulation. Engineered with a 3/8″ pre‑drilled hole, each unit fits snugly around pipe fittings while the 3/4″ layer of insulation maintains temperature stability and prevents condensation.

Designed for easy installation, the seals lock in place without the need for additional fasteners, delivering a reliable, long‑lasting seal that protects against thermal loss and moisture ingress. Ideal for commercial HVAC, food‑service refrigeration, and industrial process piping, this pack of ten ensures you have enough units for multiple connections or future maintenance.
