Bell & Gossett Oil Tube L25201 Lubricant for Pumps and Motors, 2.5 Ounce

This is the circulation pump oil recommended by Bell and Gossett and I would not consider any other.

Have used this oil for many, many years for the pump on my hot water heating system. Not able to find locally so was pleased to order it from Amazon.

Easy to add and gives peace of mind using their own brand

3 stars only because there is such a lack of instruction. The manufacturers site and certainly the bottle, gives no real clear answer on how much of this to use. I ended up using way more than I needed to before speaking with an HVAC guy. (yes, thats on me, but in the do-it-yourself age we live in they need to get with the times. YOU JUST NEED A COUPLE DROPS!!!!!

great stuf

I have an old hydronic boiler (for radiators) that had not been oiled for quite some time. This worked perfectly to keep the pump running smoothly. I only wish that it came in a larger bottle because I used most of it up in a single application.

Best oil on the planet

Excellent oil good price and fast shipping

Works great

Needed a second tube for maintenance, used the whole tube the pump came with on installation
