Perko 0541Vented Fill f/1-1/2" Hose - Straight Neck - Gas

The Perko 0541 Vented Fill for 1-1/2" Hose with straight neck design is a marine-grade fuel filler assembly built for reliable, safe fuel transfer on vessels requiring integral ventilation and flame protection. This chrome-plated bronze and black polymer filler combines essential safety features—a built-in flame arrestor and anti-surge valve—with practical deck-mounted installation, making it the choice for commercial and recreational marine operators prioritizing fuel system integrity.

The assembly accommodates 1-1/2" hose input with a dedicated 5/8" vent hose connection, eliminating the need for external vent lines and reducing deck clutter. The 3-3/8" outer diameter flange seats securely in a 2-1/8" mounting hole, while the stainless steel bead chain tether keeps the fuel cap secured during refueling operations. Construction details include a chrome-plated bronze cap that resists corrosion in saltwater environments and a black polymer body that withstands UV exposure and chemical contact. Deck plate key and O-ring are included to simplify installation and ensure watertight sealing at the deck interface.

This filler is suited for fishing vessels, patrol boats, cargo ships, and offshore support craft where fuel safety and system reliability cannot be compromised. The integral flame arrestor meets marine safety standards by preventing external ignition sources from entering the fuel tank, while the anti-surge valve protects against pressure spikes during fueling. Operators working in demanding salt-air or high-vibration environments benefit from the corrosion-resistant materials and robust deck mounting design that minimizes flexing and stress on fuel lines.
