Midland SAE 45° Flare Copper Bonnet — Soft Copper Seal
The Midland SAE 45° Flare Copper Bonnet is a soft-copper sealing bonnet that seats inside a standard SAE 45° flare connection to create a tight, leak-resistant metal-to-metal seal. Machined from soft copper so it conforms under the flare nut, it's the go-to sealing element for refrigeration, HVAC, fuel, gas, and other low-pressure tube assemblies.
