Alligator V2B Inflate-Through Valve Stem Caps 50-Pack — All-Metal, Self-Sealing O-ring for Trucks & RVs

The Alligator V2B "Gator" is a screw-on, inflate-through valve stem cap that lets you check, add, or release air without removing the cap.

Designed for heavy-duty rigs, commercial trucks, RVs and any vehicle with Schrader valves, the Alligator V2B saves time and reduces hassle by letting gauges and air lines connect through the cap. Built with an all-metal body and a self-sealing O-ring, this German-made valve cap replaces standard plastic covers and remains in place while you gauge or inflate tires in cold, dirty, or hard-to-reach conditions. Sold here as a 50-pack, these caps are meant to outfit entire fleets or large rigs so every wheel can be serviced quickly and efficiently.

How does the Alligator V2B speed up tire pressure checks?

Because the V2B stays installed, you don’t need to unscrew and reseal individual caps before and after each check. A gauge or compressor attaches directly through the cap, which reduces the number of touch steps and lowers the time per wheel dramatically.

• Attach gauge or air hose without removing the cap
• Self-sealing O-ring prevents air loss during connections
• All-metal housing withstands road grime and impacts
• One cap per valve means less fumbling in cold or tight spaces

Will these caps fit my vehicle’s valve stems?

The V2B is engineered for standard Schrader-type valve stems found on cars, light trucks, RVs, trailers and most commercial rigs. It screws on in place of the factory plastic cap and functions as a permanent, serviceable interface for inflating and gauging.

• Compatible with standard automotive and heavy-duty Schrader valves
• Universal screw-on design replaces existing caps
• Works for cars, RVs, semis, boats and trailers
• Durable threading resists cross-threading and corrosion

What are the build and durability features of the V2B?

The V2B combines a metal outer shell with an internal elastomer sealing ring to create a rugged cap that seals under pressure yet allows tools to pass through. Its construction is optimized for repeated service use and long-term exposure to the elements.

• Metal housing provides impact and wear resistance
• Self-sealing O-ring keeps valves dry and airtight when idle
• Designed and produced in Germany to proven long-term standards
• Pack quantity supports fleet maintenance and full rig coverage

How much time and effort can a fleet expect to save?

Replacing removable caps with inflate-through caps removes steps in every pressure check. For multi-wheel rigs, the cumulative savings are significant: reduced downtime, quicker inspections, and less exposure to cold or dirty conditions for technicians.

• Reduces per-rig inspection time by a large margin
• Lowers technician labor time and handling complexity
• Minimizes the need to fight seized or frozen caps
• One full set typically offsets its cost at the first or next service

Who is this for? The Alligator V2B 50-pack is intended for fleet managers, owner-operators, commercial maintenance shops, and RV owners who perform frequent tire servicing or want a faster, more reliable way to gauge and inflate tires. If you maintain multi-axle vehicles, operate in harsh climates, or aim to speed up routine checks and reduce downtime, this pack furnishes enough caps to outfit large rigs or multiple vehicles for consistent, efficient tire maintenance.
