Polyisocyanurate Tees

Polyisocyanurate (“polyiso”) tees are made from polyiso thermal insulation and are designed to fit over pipe fittings to provide thermal insulation and protection. Polyiso insulation is a closed-cell, rigid insulation with a high R-value, excellent fire resistance, and low water and vapor absorption. Polyiso tee fittings can be used in both commercial and industrial applications with service temperatures ranging from -100°F to 250°F. View our selection of polyiso tee fittings below!
