Mini check valves are machined from high purity PTFE material. Using a No O-ring, no metal spring construction, it is the ideal solution to prevent unwanted back flow situations.

  • 1/4” to 3/8” orifice
  • Low cracking pressure less than 1 PSIG
  • Designed for liquid pressure up to 120 PSIG at room temperature
