Unmatched Purity & Security
GORE™ STA-PURE® Tubing helps critical fluid handling processes run more cost-effectively. It delivers superior protection against bursting and product contamination – over a much longer time compared to conventional tubes. It maintains stable flow rates over time, handles high pressures, and virtually eliminates spallation. Using GORE™ STA-PURE® tubing means fewer changeouts and higher-purity fluid handling, so you can transfer media with utmost security and confidence.
Flexible and highly durable GORE™ STA-PURE® tubing performs exceedingly well in the most sensitive and sanitary production environments. USP Class VI compliant, its unmatched purity significantly increases process consistency and product integrity, making it an excellent choice for pharmaceutical and biopharmaceutical applications.
Burst pressures of GORE™ STA-PURE® tubing at various bore sizes
The unique composite construction of GORE™ STA-PURE® tubing provides superior burst resistance compared to non-reinforced silicone rubber and thermoplastic elastomer tubing. With burst strength approaching 360psi (24 atm), the tubing can operate at elevated pressures for filtration, transfer, and in-line sterilization operations.
The exceptional toughness of the composite structure of GORE™ STA-PURE® tubing provides superior resistance to cracking and abrasion, virtually eliminating spallation. This means the risk of filter plugging is significantly reduced without sacrificing tube life. Moreover, process streams stay cleaner, thereby reducing downstream filtration requirements. The end result: increased efficiency and throughput, along with reduced downtime.

The interior of GORE™ STA-PURE® tubing is three times smoother than thermoplastic elastomer tubing. During pumping, thermoplastic elastomer tubing develops grooves where the tube creases, causing rubber particles to be expelled into the process stream. The surface roughness increases from 1.6 microns to 3.6 microns in RMS roughness, whereas GORE™ STA-PURE® tubing shows only a slight change in surface characteristics.
