RV anti-freeze -- more than you wanted to know ?

I asked some at D&T what the difference was in ANT 15-334 and 15-384  and got a muffled reply ...so shot Record Chemical a note
---- Greg, 15-384 has corrosion inhibitors for metal protection( copper), 15-334 does not, good for poly pipe only

Images - 15-334 is pink and 15-384 is purple ... prices range from Acklands $9( better sku )  to Home Depot $5 for the cheap ...

Here are some links if you want more info ....
