for 3.5" ID Black Rubber Hoses & 3.63 ID Silicone Hoses

This T-bolt hose clamp fits on 3-1/2" ID black-rubber intake hoses, and 3-5/8" ID silicone intake hoses.

NOTE: To make clamp installation easier, remove the locknut, align the clamp while holding in place, and screw on the locknut to capture the first few threads.
