I have ~23' 3/8" od soft copper left over from my new CFC build. Was a 50' coil. Made my new CFC 25' long. Used about 2' ft more copper extending out of the hose so have about 23' left....did not measure it.
Should fit in a large flat rate box so... $20.00 for the copper and $5 shipping con US only. Paypal, CC, money order...or possible trades? Don't need much but you never know. (have cash to add if needed).
