The Haltec FE-300-7 7" Flexible Dual Wheel Valve Extension (2-Pack) is a commercial-grade inflation solution designed specifically for the inner dual wheels of RVs, motorhomes, campers, and light trucks. Built to handle heavy-duty demands, this premium extension set brings the hard-to-reach inner tire valve out to the handhole of the outer wheel, making routine air pressure maintenance quick, safe, and effortless.

Key Features & Benefits

• Effortless Tire Maintenance: Extends the inner dual tire valve by a full 7 inches, eliminating the struggle of reaching deep into dual-wheel setups for pressure checks or inflation.
• Maximum Durability: Engineered with a rugged, highly flexible casing capable of reliably handling internal air pressures up to 200 psi.
• Secure, Vibration-Free Fit: Comes complete with specialized rim stabilization clamps that securely anchor the extension to the wheel cut-out, preventing whipping, damage, or air loss from centrifugal forces during highway travel.
• Universal Compatibility: Outfitted with standard bore tire valve threads (0.305-32), ensuring a perfect, airtight fit with standard inflation chucks and pressure gauges.
