Worm Gear (Worm Drive) Hose Clamps — Product Overview
Worm gear hose clamps — also known as worm drive hose clamps — are the most widely used type of hose clamp for securing firm plastic and rubber hoses and tubes. They are frequently employed across automotive, marine, and industrial applications due to their reliable sealing performance, ease of installation, and broad size availability.
When selecting the correct hose clamp size, always measure the outside diameter (OD) of the hose or tube to ensure a proper fit within the clamp's specified clamping range.
Material Grades & Corrosion Resistance
Worm gear hose clamps are available in several material grades, each offering a different level of corrosion protection to suit specific operating environments:
Table
Material Grade | Corrosion Protection Level | Recommended Environments |
Zinc-plated steel | Fair | Indoor, dry environments with minimal moisture exposure |
18-8 / 304 stainless steel | Very Good | General-purpose outdoor and indoor use; moderate moisture and chemical exposure |
316 stainless steel | Excellent | Marine, coastal, and highly corrosive environments; exposure to saltwater, chlorides, and aggressive chemicals |
Selecting the appropriate material grade is essential for ensuring long-term durability and reliable sealing performance in your specific application environment.
