Questions about this item

How can I confirm the HVAC control fluid is performing correctly after filling the system?

Check that system pressure remains stable and operating temperature stays between -15 and 215 degrees F during normal cycling.

What comes with the 25 lb bottle and what extra items are needed for installation?

The yellow synthetic ISO 46 fluid ships in a 25 lb bottle; you will need compatible fittings, seals and any system-specific filters separately.

Which viscosity grade should I select for a hydraulic turbine circulation system?

Choose the ISO VG 46 version — its viscosity index of 111 and 440 degree F flash point match hydraulic turbine and circulation requirements.
