PSR-HT (standard wall 0.5–0.7 mm) and PSR-HTa (thickened) are the high-transparency grades of the PSR pure silicone tubing range — extruded from Japanese, US and German raw materials for fluid paths where visual flow confirmation matters: ventilator circuits, oxygen concentrators, laboratory transfer and beverage lines.
