Flomatic Stainless Steel 1" Extra Long Check Valve

Flomatic's 1" extra long 303 stainless steel spring check valve is made from the finest materials available to provide long life and superior performance. Poppets are of Delrin with Buna N rubber sealing discs and stainless steel springs. These check valves are suitable for use in water, oil and gasoline.

This extra long check valve has more space between the valve and the threads so the pipe or fitting used will not interfere with the check valves operation.

  • 303 Stainless steel body and spring.
  • Buna-N seal.
  • Max Temperature 180°F (80°C).
  • Max Pressure 400 PSI.
  • Thread Sealants: Teflon Tape or Paste?

    Teflon tape is a quick and clean way to seal threads in most applications. When applying Teflon tape, care must be taken to apply the tape correctly or leaking may still occur. You should wrap the thread 2-3 times around the threads in a counter-clockwise direction so that the tape doesn't bunch up when it is screwed into the pipe. Do not over tighten, as this may cause the tape to become thin or break in spots, while under tightening may allow water through.

    For professional, long-term or industrial applications, Teflon paste, although messy and more difficult to apply, will provide a more reliable seal that won't leak if the plastic pipe distorts over time. Teflon paste should be applied to both the male and female threads.
