Our silicone adapters and couplers are made out of 1/8" thick,
polyester fabric reinforced silicone, which meets or exceeds SAE J20
Standards. These adapters and couplers can withstand temperatures of
-20 degrees F to 350 degrees F. Each adapter has a high-gloss black finish that will
look great under the hood.
