Bare Tubing


O'Brien starts with select ASTM grade tubing and enhances its physical characteristics to improve dry-down, adsorption and corrosion resistance. We do this by controlling surface roughness, cleanliness, surface chemistry and reactive contaminants.

TrueTube is available in orbital weld fittings, striaght sticks and long continuous lengths of electropolished (TrueTube EP) and electropolished tubing with a deactivated fused silica lining (TrueTube EPS).
