Uharbour 4-Tire Inflation Deflation System — 155" Wheelbase, 1/4" Coupler, Fast Simultaneous Air Up/Down

The Uharbour 4 Tire Inflation Deflation System lets you inflate or deflate all four tires at once, saving time and delivering consistent pressure across vehicles with up to a 155" wheelbase.

Designed for drivers, off-roaders, fleet operators and weekend mechanics, this compact multi-hose kit connects to your air compressor and balances tire pressure quickly and reliably. The system works with standard 1/4" industrial male and female couplers, includes 360° swivel tees to prevent hose kinks, and its flexible hose layout reaches across trucks, vans and SUVs with long wheelbases.

How does this system speed up tire pressure work?

Instead of treating each tire separately, the Uharbour 4-tire system links all four valves to one compressor source so air can be added or released simultaneously. That cuts the time spent at each wheel and reduces repetitive checking.

• Connects to a single compressor via 1/4" IM male or female coupler.
• Four hoses run to each valve for simultaneous inflation/deflation.
• Balanced pressurization helps achieve matching pressure across tires faster.

Can I use it for both inflating and deflating tires?

Yes — the system is built to handle both adding air and letting air out. Using the same set of hoses and fittings, you can quickly tune pressures for highway driving or reduce pressure for off-road traction.

• Quick-switch operation lets you alternate between air-up and air-down tasks.
• Durable connectors maintain airtight seals during pressurization and venting.
• Same hoses and couplers work across both functions with no extra parts needed.

Will this reach my vehicle’s tires if I have a long wheelbase?

The kit is configured for vehicles with wheelbases up to 155 inches, so it covers most trucks, vans and extended SUVs. Hoses and swivel tees are arranged to give ample reach and freedom of movement around each wheel.

• Flexible hose length designed to span up to a 155" wheelbase.
• 360° swivel tee connectors prevent kinking when moving around wheels.
• Layout works well for staggered wheel positions on light trucks and SUVs.

What compressors and fittings are compatible?

Uharbour includes a 1/4" industrial male and female coupler arrangement so the system mates with most shop and portable compressors. That avoids the need for special adapters in many setups.

• Includes 1/4" IM male and female coupler compatibility.
• Works with typical workshop and portable compressors that use 1/4" fittings.
• Swivel tee design reduces stress on compressor hose connections.

Who is this for: The Uharbour 4 Tire Inflation Deflation System is ideal for anyone who services multiple tires regularly — utility fleet managers, off-road enthusiasts who change tire pressures often, drivers of full-size trucks and vans, and home mechanics who want a faster, neater solution than repeating single-valve inflation. If you value time savings, consistent pressure across all four tires, and compatibility with standard 1/4" compressor fittings, this kit is a practical addition to your air tool collection.
