3/4" BSP Stainless Steel 304 Sight Flow Indicator With Rotating Impeller – DN20

Need to see if your liquid is actually moving through the pipe?

This is the gadget for you.

It's a 3/4-inch BSP sight flow indicator made from solid stainless steel 304, so it's built to last.

Inside, there's a little plastic impeller that spins when fluid flows, giving you a clear visual confirmation that things are moving.

Perfect for water, oils, or other non-corrosive liquids.

It's a brand-new, unbranded unit, but the build quality is solid.

Whether you're setting up a cooling system, a pump rig, or just need to monitor flow, this little guy does the job.

Just screw it in with the BSP threads and you're good to go.
