Mityvac's Locking Hose Clamp, No. MVA7607, secures flexible hoses during automotive diagnostics and repairs. It comes 8" (200 mm) in length with angled jaws to access hard-to-reach vehicle hoses. The jaws extend to securely clamp hoses up to 1-1/4" (30 mm) in diameter and can apply up 50 lbs (23 kg) of force. The lightweight hose clamp comes composed of durable, non-marring, glass-filled nylon that resists oil and other common automotive fluids and chemicals. Its jaws have rounded edges that won’t cut hoses, and the large, comfortable grips have non-slip ribs and finger guards.
