Hose Clamp Size Comparison
- ABA #8 — 5/8" to 1" — Small-bore: fuel vent, livewell, bilge intake (SKU ABA-13624)

Always measure your hose outside diameter before selecting a clamp. The clamp range must fully encompass the hose OD with room to tighten.
Installation Notes
Double-clamp all below-waterline and fuel hose connections per ABYC H-27 and A-21 standards. Position clamps so the band fully covers the hose bead or fitting barb. Tighten to the fitting manufacturer's torque specification — do not overtighten, which can cut or collapse the hose. Inspect annually for corrosion, loosening, or hose deterioration and replace as needed. Never substitute zinc-plated (non-marine) clamps in marine applications.
The IDE-HAS28 delivers reliable, corrosion-resistant clamping for the medium-to-large bore hose connections found throughout marine engine and plumbing systems.
