Kinsler Flapper Check Valve



Kinsler Flapper Check Valve

Aircraft grade, this hinged-flap “toilet seat” check valve is excellent for use as a roll-over valve, in multiple tank fuel systems or as an anti-back flow valve. Hinged-flap has captive O-ring for excellent seal when closed. Essentially, this valve stops fluid returning back down the line once flow is stopped.


  • Gasoline and methanol compatible
  • Hard anodized aluminium

Check Valves – Flapper Options:

  • 8AN Male Flare Inlet and Outlet (#3092)
  • 10AN Male Flare Inlet and Outlet (#3097)
  • 12AN Male Flare Inlet and Outlet (#3098)

When choosing your flapper check valve, select the 8AN side that correlates with your fuel line.

At Street Race Solutions, we utilise this valve as part of our fuel system, placed between the fuel tank and mechanical fuel pump to ensure fuel is kept readily available for the fuel pump. Please contact us if you have any questions regarding this part!

If you require a valve smaller than 8AN or greater than 12AN, please get in contact as well for a custom order!
