I'd like to replace this old toilet copper supply line with a more flexible braided supply line.
The problem is that I can't find one with the right connection to the water supply valve.
Current (copper) connection:
The two closest replacements I have found are:
1)
BrassCraft Model# "B3-12DL F"
Description:
"1/2 in. Compression x 7/8 in. Ballcock Nut x 12 in. Braided Polymer Toilet Connector"
2)
BrassCraft Model# "B8-12DL F"
Description:
"1/2 in. FIP x 7/8 in. Ballcock Nut x 12 in. Braided Polymer Toilet Connector"
Images of BrassCraft models:
By my measurements, the interior diameters are:
– Current connection: 11/16 inch
– BrassCraft model B3-12DL F: 10/16 inch (1/16 inch too small)
– BrassCraft model B8-12DL F: 12/16 inch (1/16 inch too large)
The connection types of the two models is different (one is 1/2 in. Compression and the other is 1/2 in. FIP). I don't know what type is necessary to replace the old line (maybe neither of those), but the FIP (Model B8-12DL F) looks more similar to the existing connection.
If anybody has any insight regarding how I can connect a new flexible braided supply line (without replacing the water supply valve itself), I'd greatly appreciate it!

That shutoff looks super old. I would turn off the main shut off, cut off the old shutoff and get a push-fit shutoff and toilet supply line. The new shutoff will be about $10 and the supply line will be about $5. You will also need a copper cutter or hack saw and possibly a meter key and pliers.
