Koehler micro clamps are precision engineered to provide reliable, long-lasting performance in small diameter hose applications such as fuel lines, air & vacuum hoses and emission control. These clamps feature 5/16 inch bands constructed of 300 series stainless steel for maximum corrosion resistance to salt and most chemicals. The low profile housing and 1/4" hex head screw are both produced with plated carbon steel and are small enough to allow installation within hard to reach spaces with limited access. This pack includes 4 pieces of Size 4 hose clamps with a clamping range from 1/4 inches to 5/8 inches.
