Product Details

The Forespar 903007 Marelon Vented Loop prevents unwanted siphoning between tanks in marine plumbing systems. This essential safety device allows air to enter the line when not in use, breaking the siphon effect, while automatically sealing when water or other fluids pass through.

Key Features:

  • Molded from lightweight, high-strength Marelon marine-grade polymer
  • 1" hose barb fittings on both ends for secure connection
  • Duckbill one-way valve design seals properly even with particulate matter present
  • Zero electrolysis and completely corrosion-resistant construction
  • UV stabilized to resist degradation in direct sunlight
  • High tensile strength and excellent abrasion resistance
  • Operating temperature range: -40°F to 176°F (-40°C to 80°C)
  • Dimensions: 7" height x 9" width
  • Exceeds ABYC and ISO marine standards

Ideal for marine toilet systems, engine cooling applications, and any marine plumbing where preventing reverse flow is critical. The Marelon construction ensures long-lasting performance without the corrosion issues associated with metal vented loops.
