Virtually Eliminates Spallation
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.

Smooth Bore Reduces Contamination
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.
