Pharma-Clear® 65
Silicone Tubing

The SaniSure® Pharma-Clear® 65 tubing is made for bulk transfer and general peristaltic pumping applications. With a slightly higher hardness rating, this tubing has very good resilience and kink resistance. In addition, it typically has a higher pressure rating than softer alternatives.

Our Pharma-Clear® 65 also exhibits superior optical clarity.
