Secure Keyed Locking Cap | Straight Neck Design | 316 Stainless Steel | Fits 1.5" (38mm) Diesel Hose
Product Overview
Protect your marine fuel supply and upgrade your deck aesthetics with the RiaYer 1.5" Straight Diesel Deck Fill. Designed for direct vertical hose drops in harsh saltwater environments, this "Straight" neck filler is cast from solid marine-grade 316 stainless steel with a high mirror-polished finish. Unlike standard caps, this model features a Keyed Locking Mechanism to prevent fuel theft and unauthorized access. Complete with a retaining chain and dual-seal gaskets, it ensures your boat's diesel tank remains secure and perfectly watertight in rough seas.
Key Features
- 🔒 Anti-Theft Keyed Cap: Equipped with a built-in heavy-duty locking cylinder and two keys. Provides absolute peace of mind by securing your diesel tank against tampering at the marina.
- ⚓ Premium 316 Stainless Steel: Crafted from superior 316 marine-grade steel for maximum rust and corrosion resistance. The hand-polished surface adds a luxury touch to your boat deck.
- 📏 Straight Neck Design: Ideal for installations where the fuel hose runs straight down into the hull directly below the mounting point, offering the most direct and fastest fuel flow.
- 💧 Dual-Seal Watertight System: Features a high-grade O-ring inside the cap and a rubber mounting gasket for the flange, effectively sealing out rain, sea spray, and keeping fuel odors locked in.
- 🔗 Loss-Prevention Chain: A durable stainless steel retaining chain connects the locking cap to the fill body, ensuring you never drop or lose the cap overboard during refueling.

Frequently Asked Questions (FAQ)
Q: When should I choose this "Straight" model over an "Angled" one?
A: A Straight neck is perfect when you have plenty of vertical space directly below the mounting surface, allowing the fuel hose to drop straight down into the tank. This provides the fastest and most direct refueling path.
Q: Can I use this for Gasoline or Water tanks?
A: We strictly recommend using this for DIESEL systems only. The cap is permanently engraved with "DIESEL" to prevent dangerous cross-contamination at the fuel dock.
Q: What size hose does this fit?
A: This unit fits standard marine fuel hoses with a 1.5-inch (38mm) Inner Diameter (I.D.). The barbed neck is slightly oversized (1.52") to ensure a tight, leak-proof seal when clamped.
Q: Are the keys universal or unique?
A: The keys are standard for marine deck fills, providing an excellent deterrent against casual theft and tampering at busy marinas, giving you peace of mind when leaving your boat unattended.
