Full Product Description

Parker's STW/STB “True-Bore” Hose differs from other smoothbore PTFE hoses because these hoses have a larger inside diameter to speed up the flow of the media through the tube. For example, an S30-6 PTFE hose has a nominal inside diameter of 5/16 whereas STW-6 “True Bore” hose has a nominal inside diameter of 3/8.  The increased I.D. speeds up the flow of the media traveling through the tube and, in some cases, allows the hose to carry up to 15% more flow.

STW/STB “True-Bore” Smooth Bore Stainless Steel Braided PTFE Hose maintains excellent chemical compatibility, resists moisture and is capable of withstanding high temperatures up to 450°F/260°C. It exhibits high performance in applications that involve fluid handling, chemical transfer, food and beverage, paint, pharmaceutical and cosmetics.
