Help identifying thing on pipe

Anyone know what that rusty metal round thing might be that is attached to the top of my pipe on the right side there (just above the black Jandy Valve)?
Wonder if something used to be mounted there.

Looks like it could be a temperature probe as it is located after your pump. Is there a place to connect a wire to it? Maybe post a close up picture of that device.
Alternatively, it could be an hose connection but difficult to see the details of it.

Looks like a pressure switch to me.

Could it be the connector for your water bonding?

Agree it does look like that pressure switch.
It does have a place to attach a wire - you can see on the right side.
No wires going to it, so I'm guessing it isn't bonding (I haven't seen any signs of bonding around my setup).

Soo... what is a pressure switch for?

I don't have a heater, so not sure why a temperature probe would be needed (its possible that previous owners had a heater at one point).

To me that is a flow switch not a pressure switch. You will see NC = Normally Closed and NO = Normally open on the body. The common terminal is corroded off. When the pump is running the C and the NO terminals will be shorted. The most common use for these is chemical dosing such as a SWG or a chlorine/acid tank. Most heaters have these internally so I doubt it was for a heater.

That is an old pressure switch. Why it is there is anyone's guess. If there was ever a slide on the pool it might have been the water supply port that just needed to be plugged and an old switch was handy. I have seen many DIY projects by owners or service people that will use a pressure switch to activate a small water feature pump, or the like, with the proper circuitry. It may have been used for a chemical dispenser instead of a flow switch. Since it is not being used and is rusting, it will eventually start to leak. Replace it with 1/4" plastic, nylon, or brass pipe plug to be safe

I think that it's a 1/8" npt thread.

It could easily be 1/8". Buy one of each and put the un-used one in a drawer. Wouldn't be worth a return to the store. Make sure to use adequate Teflon tape or thread sealer designed for plastic.
