FL-3 Fitting Flange

• 1 ¼” BSP thread and 5 hole equal pattern
• Converts 5 hole bolt-down pattern to 1 ¼” BSP thread
• Supplied with Nitrile Gasket
• Hole size – 5mm

Fitted to topside of tank to create 1 ¼” BSP thread.

The FL-3 can be used, if you don’t need the under-ring  FLS-U. It has larger screw holes, so larger screws can be used, if needed.

This flange is used to mount the S3 type sensor in the tank. A nitrile rubber gasket is included.

For mounting in tanks with a thin top it is recommended to use an HFL flange or FL-2 flange together with an  FLS-U inner ring to secure against leaks.  The FL-2 has a standard SAE-5-hole pattern.
