All-stainless worm-drive hose clamp from Ideal Clamp Products. The 300 series uses 300-grade stainless on the band, housing, and screw for stronger corrosion resistance than standard band-only stainless clamps, well-suited for outdoor, marine-adjacent, and washdown environments.

• 300 Series stainless steel band, housing, and screw throughout for full corrosion resistance
• Worm-drive slotted band distributes clamping force evenly around the hose
• Hex/slotted screw drives with a hex socket or a flat-blade screwdriver
• Clamping range: 1-9/16" to 2-1/2"
• Common uses: outdoor plumbing, irrigation, marine-adjacent applications, coolant connections in harsh environments

Tip: Position the clamp about 1/4" back from the cut end of the hose and tighten only until the hose surface deforms slightly under the band. Over-tightening can cut soft hose.
