A/C and Heater Firewall Rings Billet Aluminum

Billet aluminum firewall rings to run four hoses (two heater, two a/c) through the firewall.
The a/c rings have to be slid on the hose prior to crimping the line.   These firewall rings are a great way to avoid metal cutting into the hoses, while keeping a clean look.  

• Firewall ring diameter:
• #6 hose 15/16" mounting hole diameter / 1-3/16" outer diameter
• #10 & heater hose 1-3/16" mounting hole diameter / 1-3/8" outer diameter
