Standard Elbow Vents Leak, Corrode & Sit Proud of the Deck — This Flanged Bowl Design Seals Flush and Lasts for Years

A bare 90° elbow vent without a proper deck flange is an invitation for water ingress, fuel vapor leaks, and an ugly installation that never sits flush. This 90° elbow marine fuel tank vent with integrated flange bowl solves all three problems in one fitting. The wide stainless steel flange bowl seats flush against the deck surface, creating a clean, professional finish while the rubber O-ring underneath seals out water completely. The mirror-polished finish resists corrosion and surface oxidation in saltwater environments, and the smooth rounded edges won’t snag lines or injure crew. Available in three sizes — A (46mm bowl), B (51.6mm bowl, 177g), and C (77.35mm bowl, 4-screw mount) — to fit any deck thickness and tank configuration.

Product details

Key Features

Integrated Flange Bowl – Wide stainless flange seats flush on deck; eliminates the gap and water ingress point of bare elbow vents
Mirror-Polished Stainless Steel – Electropolished surface resists corrosion, staining, and oxidation in saltwater and UV environments
Smooth Rounded Edges – No sharp edges to snag lines, injure crew, or scratch gelcoat during installation
90° Elbow Configuration – Horizontal hose exit ideal for side-of-hull or tight-space installations; prevents direct water entry into vent opening
Rubber O-Ring Seal – Deck-mount O-ring creates a watertight seal between flange and deck surface
3 Sizes Available – Style A (compact, 46mm bowl), Style B (mid-size, 51.6mm bowl, 177g), Style C (large, 77.35mm bowl, 4-screw flange)
Wide Application – Boats, yachts, pontoons, aluminum hulls, fiberglass decks, RVs with fuel tanks

Solves These Common Problems

Water ingress through bare elbow vents without a proper deck flange seal
Corroded or pitted vent fittings from inferior stainless or chrome-plated zinc
Vents that sit proud of the deck and snag lines or create trip hazards
Fuel vapor leaks from poorly sealed deck penetrations
Ugly, non-flush installations that look unprofessional on a premium vesse
