Fluid & Air Line Solution
Mobile Custom Hose & Line Repair
Mobile Diesel Repair LLC offers on-site custom hose and line services for trucks and heavy equipment. We build and replace hydraulic, air, fuel, oil, coolant, and power steering hoses on the spot — fast, reliable, and Parker certified.
Hose, Fittings and Equipment
Mobile Diesel Repair LLC provides on-site custom hose replacement and fabrication using professional Parker crimping equipment. Whether it’s hydraulic, air, fuel, coolant, oil, or power steering lines — we build and install hoses that meet OEM standards right where you need them. Parker fittings and components ensure precision, durability, and leak-free performance you can trust to keep your equipment running strong.
Reasons to Replace Your Hoses
• Leaks and Pressure Loss
Leaking hose means downtime. Loss of hydraulic pressure or air flow can stop your truck or equipment instantly. On-site replacement gets you back to work without waiting for a shop.
• Burst or Blown Hoses
A hose failure under pressure can be dangerous and costly. Replacing damaged hoses immediately prevents fluid loss, contamination, and potential safety hazards.
• Wear, Abrasion & Heat Damage
Constant vibration, friction, and high heat wear down hose covers and fittings. New Parker hoses resist abrasion and are built to handle extreme temperatures and heavy-duty use.
• Aging or Swollen Hoses
Over time, hoses break down from oil, fuel, coolant, or environmental exposure. Replacing old or swollen lines prevents breakdowns and keeps systems operating efficiently.
• Damaged or Corroded Fittings
Rusted or bent fittings cause leaks and poor sealing. Parker fittings provide precise crimps and leak-free connections that meet or exceed OEM standards.
• System Upgrades or Modifications
When adding new equipment or reconfiguring lines, new hoses ensure proper length, flow, and pressure rating. On-site fabrication saves time and guarantees a perfect fit.
• Air Leaks in Brake or Suspension Lines
Air leaks reduce braking efficiency and can cause loss of air pressure in the system — a major safety risk. Replacing cracked or dry-rotted air hoses keeps brakes, suspension bags, and valves working properly.
• Worn or Loose Air Fittings
Old or damaged air line fittings leak under vibration and pressure. New Parker air fittings provide a tight seal that prevents constant air loss and keeps your compressor from overworking.
Transportation Hoses
Parker transportation hoses are designed for on-vehicle use — ideal for trucks, trailers, and heavy equipment. They handle air-brake, power-steering, fuel, coolant, and hydraulic return lines with rugged reliability in demanding environments.
Pressure & Performance
Depending on the series, Parker transportation hoses handle roughly 200 to 3,000 PSI, covering most mobile-equipment needs. They’re flexible, abrasion-resistant, and built to perform in tight routing spaces and harsh vehicle conditions.
How They Differ from Hydraulic Hoses
Transportation hoses meet SAE and DOT standards for on-road service, focusing on vibration resistance, fuel and coolant compatibility, and flexibility. Hydraulic hoses, by contrast, are built mainly for stationary or high-pressure fluid-power systems.
Pros
• Designed for mobile and road applications
Excellent flexibility and abrasion resistance
Compatible with multiple fluids (fuel, oil, coolant, air)
Certified for DOT and SAE use
Cons
• Not ideal for extreme high-pressure
systems over (3000) PSI
May have a shorter lifespan under constant high-heat or UV exposure
Slightly higher cost than basic hydraulic hose
Why It Matters
For trucks and heavy equipment, Parker transportation hoses strike the right balance between strength, flexibility, and safety. They’re purpose-built for mobile systems — and at Mobile Diesel Repair LLC, we build and replace them on-site with Parker-certified precision.
Temporary Reusable Hose Repair Fittings
When you’re stuck with a damaged hydraulic or air hose, these Parker reusable fittings are the perfect solution to get you back on the road fast. Designed for emergency or temporary repairs, they quickly stop leaks in hydraulic and air lines — even on larger or longer hoses. Available in 1/4”, 3/8”, and 1/2” sizes, these fittings are DOT-approved and built tough to hold pressure until you can make a permanent replacement.
