The IDEX Nonmetallic Check Valve, 1 psi, 0.020 in, 1/4-28 F-F (CV-3330; Cole-Parmer item 02015-93) is a biocompatible inline check valve designed to limit fluid flow to one direction. It features a 1 psi cracking pressure, 34 µL swept volume and female-to-female 1/4-28 flat-bottom connections with a 0.020 in through hole. Its metal-free PEEK and perfluoroelastomer construction provides chemical resistance for fluid paths involving corrosive fluids and biological samples.
Key Features
- Biocompatible, metal-free construction, suited to fluid paths involving biological samples and corrosive fluids
- PEEK and perfluoroelastomer wetted materials, providing excellent chemical resistance
- Low 1 psi cracking pressure, equivalent to 0.07 bar
- Maximum pressure rating of 2000 psi, equivalent to 138 bar
- Low 34 µL swept volume, helping minimise fluid retained within the valve
- 0.020 in through hole, defining the fluid passage for this CV-3330 configuration
- Female-to-female 1/4-28 flat-bottom ports, providing the verified connection arrangement at both ends
- Inline back-flow control, helping protect upstream components from reverse fluid movement

Benefits
- Helps protect sensitive upstream equipment and fluid paths by restricting reverse flow.
- Supports low-volume fluidic systems where minimising swept volume is important.
- Provides a metal-free option for workflows where biological samples or corrosive fluids are handled.
- Simplifies integration through matching female 1/4-28 flat-bottom connections on both ends.
- Combines low cracking pressure with a high verified maximum pressure rating for controlled directional flow.
Why Choose the IDEX Nonmetallic Check Valve, 1 psi, 0.020 in, 1/4-28 F-F (CV-3330)?
The IDEX CV-3330 combines biocompatible nonmetallic wetted materials, low swept volume and a 1 psi cracking pressure in a female-to-female 1/4-28 configuration. It is designed for directional flow control where chemical resistance and low fluid-path volume are important. As IDEX currently lists CV-3330 as obsolete, contact John Morris Group to confirm availability or discuss an appropriate replacement.
