Different Fit

Other reviews said this would fit existing Pentair OEM, but I had to enlarge the hole in plumbing to make it fit. I would have preferred to keep the existing hole but was able to get a leak free fit. The wires aren’t copper but insulation seems thicker and it was easy to replace existing sensor wiring into the controller box. I had to recalibrate the gauge and it seems to be taking accurate readings and working better than the old sensor. Would have rated higher if it would have fit without having to drill.

Sensor works great and the price was great!

This sensor from PGS was recommended on TFP and it is working well, replacing the faulty 3 year old Pentair sensor.

Received the thermocouple today (great

Received the thermocouple today (great shipping time) and installed it. Although it wasn't a perfect match to the original, it works great. Thanks.

My order arrived just two

My order arrived just two days after I placed my order. Can't beat that. Great service, best price. Thanks guys.

This is an after market

This is an after market product, which is probably a good thing, being as I've gone through two of the OEM temp sensors in as many years. This one was an exact fit and is working just fine. Plus, it's less expensive. I bought a few extra however, just in case.
