Sierra 16-120-0340BS Shields Bilgeflex 3/4" x 500' Black Bilge Pump Hose

The Sierra 16-120-0340BS is a 3/4" x 500-foot bulk roll of Shields Bilgeflex corrugated bilge pump hose in black. Constructed from a single layer of corrugated polyethylene, this flexible hose is engineered for above-the-waterline bilge pump discharge, livewell, and pump intake applications aboard marine vessels.

Key Features:

• Single-layer corrugated polyethylene construction for excellent flexibility and durability
• 3/4" (19.1mm) inside diameter with a 3/4" minimum bend radius for tight routing in confined bilge spaces
• Resistant to salt water and mild chemicals, ideal for the harsh marine bilge environment
• Clamping cuff molded every foot for easy cutting, installation, and secure hose clamp placement
• Vacuum rating of 20 for reliable pump intake performance
• 500-foot bulk roll — ideal for boatbuilders, dealers, and high-volume service operations
• Meets standards set by the USCG and ABYC

Important: This hose is designed for above-the-waterline use only. Do not attach to a thru-hull fitting below the waterline. Typical applications include bilge pump discharge, pump intake, and livewell aerator plumbing.
