About this item
Upchurch Scientific® Nonmetallic 1/4-28 Inline Check Valves provide excellent backflow protection for sensitive equipment along with outstanding chemical resistance guaranteed by the PEEK™ polymer and perfluoroelastomer construction
These Check Valves function well up to moderately high-pressure applications. Low internal volume allows these to be used in areas where flow path volume is important. However, higher flow rates can pass through with minimal pressure drop.
Note: Upon initial use, or following a period of exended inactivity, the cracking pressure for these check valves may be somewhat higher than the stated cracking pressure.
Additionally, the metal-free composition of these Check Valves makes them perfect for use with corrosive fluids or biological samples.
