A leaking air hose is easy to miss until it leaves you stuck. A hiss at the gladhands, air pressure that drops after you shut down, or a line that has rubbed through against the frame can leave you short on air, fail a roadside inspection, or keep your trailer brakes from releasing. Tire Installation LLC provides mobile Air Hose Repair in Memphis TN for tractors and trailers, right where they are parked.
Our techs come to your yard, dock, or roadside location with the hoses, fittings, and tools to find the leak and fix it on the spot. That includes tractor-to-trailer air lines and coils, gladhands and seals, brake hoses at the axles, and fittings and push-to-connect joints. With more than 30 years in business, we explain what we find in plain words, give you upfront pricing before we start, and send photo proof when the job is done.

Air Hose Repair in Memphis TN: What We Fix On-Site
Most calls for Air Hose Repair in Memphis TN can be handled at the truck without a tow. Here is what our mobile techs work on most often.
Tractor-to-Trailer Air Lines
The service (blue) and emergency (red) air lines carry air from the tractor to the trailer brakes. Coiled lines get stretched, pinched between the cab and trailer, and worn where they rub on the deck plate. A cracked or chafed line can leak enough air to slow pressure buildup or set the trailer brakes. We replace damaged lines and coils and make sure they are routed and supported so they do not wear through again.
Gladhands and Seals
Gladhands connect the tractor’s air lines to the trailer. A torn or flattened rubber seal, a cracked gladhand, or a bent coupler can cause a steady hiss and a loss of pressure every time you hook up. We replace gladhand seals, gladhands, and gladhand mounts on-site, then check that the connection locks and seals properly.
Brake Hoses and Fittings
Short rubber brake hoses at the axles flex every time the suspension moves, so they crack and chafe over time. Fittings and push-to-connect joints can loosen or start leaking from constant vibration. We replace worn hoses, fittings, and connectors with the correct heavy-duty parts. If we spot worn brake parts while we are under the truck, see our brake replacement services.
Finding and Fixing Air Leaks
An air leak makes your compressor work harder, slows pressure buildup, and can eventually leave you without enough air to release the parking brakes. Leaks also show up during roadside checks, which can mean delays you did not plan for.
Where Leaks Usually Hide
- Gladhand seals and connections between tractor and trailer
- Air lines that have rubbed, cracked, or kinked
- Fittings and push-to-connect joints
- Brake hoses at the axles
- Hose clamps and line supports that have worn loose
We run a pressure check with the brakes released and applied, listen for leaks, and use leak detection solution on hoses, fittings, and lines to pin down the source. Then we replace the damaged seal, fitting, hose, or line. We tell you if a problem is beyond a roadside fix, such as internal valve or compressor work that belongs in a shop, so you can plan the next step with real information.
A slow leak is also a common reason a truck sits overnight and will not build pressure in the morning. If that is your situation, our emergency roadside assistance team can help get you moving.
DOT-Focused Air Line Checks Before Inspection
Air leaks are one of the most common reasons trucks get placed out of service during roadside inspections. Audible leaks, chafed or damaged hoses, and bad gladhand connections are all things an inspector will look for.
We offer DOT-focused air line checks that look at the same items so you can fix problems before an inspector finds them. To be clear, we do not perform official DOT inspections or issue certifications. What we do is give you an honest look at your air lines and hoses and fix what needs fixing.
What an Air Line Check Covers
- Tractor-to-trailer air lines and coils
- Gladhands and gladhand seals
- Brake hoses at each axle
- Fittings and push-to-connect joints
- Line routing, clamps, and supports
- Air pressure buildup and leak-down
You get photo notes of what we found, a clear list of what needs attention, and upfront pricing on the repair. Fleets can pair air line checks with scheduled yard visits through our fleet tire management program, and owner-operators can book a check before a long run.

Upfront Pricing
You get a free estimate before we start any work, based on what we find and the parts needed. No surprise add-ons. If our tech uncovers another problem once we are under the truck, we stop, show you photos, and explain the options before anything else is added to the job or the final bill.
Photo Proof of Work
Air hose work happens under the truck and between the cab and trailer, where you cannot easily see it. We photograph the damaged hoses and fittings, the replaced parts, and the finished job. That gives you a record for your maintenance file, proof for your fleet manager, and peace of mind that the work was done the right way.
Same-Day Bookings
Book online or call, and same-day appointments are available when the schedule allows. You get text appointment alerts so you know when the tech is on the way, and rescheduling is easy if your load plan changes. We come to your yard, dock, or roadside spot so the truck does not need a tow.
Frequently Asked Questions
Common signs include a hiss you can hear when the truck is parked, air pressure that drops after you shut down, slow pressure buildup, or trailer brakes that will not release. The most reliable way to know is a pressure check with the brakes released and applied. We test the system, trace the leak to the exact hose or fitting, and replace the failed part.
In most cases, yes, as long as the location is safe to work in. We carry common air lines, coils, gladhands, seals, brake hoses, and fittings. If the location is unsafe, such as a narrow shoulder with heavy traffic, we may recommend moving the truck to a safer spot nearby first, when that is possible.
No. We do not perform official DOT inspections or issue certifications. We offer DOT-focused air line checks that cover the items inspectors commonly look at, like audible air leaks, chafed hoses, and gladhand connections. That lets you find and fix problems ahead of time, so your inspection goes more smoothly and you are less likely to be delayed.
Audible leaks usually come from gladhand seals, cracked air lines, loose fittings, or a leaking brake chamber diaphragm. A leak that shows only with the brakes applied often points to a chamber or valve. We pressure test the system, trace the leak, and replace the failed part. Some valve or compressor issues may need shop work.
Yes. We repair air lines, brake hoses, gladhands, and fittings on both tractors and trailers. If you are already having trailer tires changed, ask us to check the air hoses at the same time, since we are already working under the trailer.
