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

Ive used this oil on the circulating pump for our boiler and it works great. I also use it on my bench grinder and miter and table saws with the same results.

Maintenance.

I use for me sistem very good product on cualyty

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

Great to have since I did not know that the circulator needed to be oiled. My bad completely, I have never oiled this pump in 12 years. A testament to this B & G series 100 pump that it was still running! Oil your pump and the technical manual is HS-105-SM-R4.

Used other oils and the pump stayed noisy all year. This oil immediately quieted it down.

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