Billet Proof Designs OE-style black plastic gas cap is a vented, right-hand-thread replacement for 1992–2026 Harley Touring models with tank fuel doors, featuring nylon threads, a rubber seal and ratchet overrun protection.

This gas cap replaces Harley part number 61274-92 and is built to match original equipment fit and function for Road King, Road Glide, Street Glide and Electra Glide motorcycles made from 1992 through 2026.

How does the venting and sealing work on this cap?

The cap incorporates a vented design that allows controlled pressure equalization while the rubber seal minimizes fuel vapor escape when closed. Vented caps reduce pressure build-up in the tank, which helps fuel delivery and prevents vacuum-related issues without compromising the seal. The rubber gasket provides a tight barrier against leaks when the cap is fully seated and latched.

• Vented design for pressure equalization
• Rubber seal to limit fuel vapors and leaks
• Secure seating to maintain a reliable closure
• Maintains OEM tank ventilation behavior

What materials and features make this cap durable?

Constructed as an OE-style black plastic cap, it uses nylon for the threaded portion to resist wear and galling, and a resilient rubber seal that withstands fuel exposure. The ratchet overrun protection prevents overtightening by letting the cap click once properly seated, which reduces thread stress and extends service life. Together these features give long-term, maintenance-free performance in typical riding conditions.

• Nylon threads for corrosion and galling resistance
• Rubber seal formulated for fuel exposure
• Ratchet overrun protection to prevent over-tightening
• Black OE-style finish for a factory look

How hard is it to install and maintain this cap?

Installation is straightforward — thread the cap in by hand until the ratchet clicks to indicate a proper seal; no tools or adapters are necessary. Maintenance is minimal: periodically inspect the rubber gasket for cracks and clean debris from the cap and filler neck to ensure an airtight seal. If the gasket shows wear, replacement prevents vapor leaks and maintains venting performance.

• Hand-tighten until ratchet clicks — no tools needed
• Inspect gasket periodically for wear and replace if needed
• Keep filler neck and cap clean from dirt and grit
• Simple swap-in for existing OEM cap (HD# 61274-92)
