FOR PRECISION PLANTING

WHO FEED
THE WORLD FOR THOSE
Kanaflex has always built for the people who grow, move, and feed the nation. The flexFLO™ U 190 is the culmination of years of engineering and field testing.

Designed for consistent flow, flexibility in any condition, and abrasion resistance against the toughest seeds and fertilizers.

AIR SEEDER HOSE YET!
WHERE PERFORMANCE BEGINS

SEED STARTS HERE
The primary hose is the heart of the system. It is the main transport line that carries the bulk mixture of seed and fertilizer to the distribution manifold. The primary hose experiences extreme abrasions and if damaged impacts the entire machine, making it the most important hose within any air seeder system.
flexFLO™ U 190 is engineered for extreme abrasion resistance, shape retention, laminar flow and bend stability. After years of field testing, U 190 has proven to be the best primary and secondary air seeder hose in the market.
PVC BEYOND
A NEW STANDARD FOR AIRFLOW
Air Seeding is high-velocity fertilizer and seed acting like a continuous sandblaster inside the hose. PVC fights that environment and eventually wears out. Polyurethane has superior abrasion resistance compared to PVC and rubber, remaining flexible in cold spring conditions.
flexFLO™ U 190 features a full polyurethane tube made with proprietary hydrostabilizer formulation. Combined with its advanced polymer helix design, the U 190 result is longer service life, and less downtime in the middle of planting. It is built for the job, not just priced for it.

PROVEN WHERE IT MATTERS
IN THE FIELD
Field testing over 9,000 acres proved the difference a purpose-built hose makes. The smooth inner wall delivered 10% higher airflow, allowing urea fertilizer and seed rates to match agronomist variable-rate maps with greater accuracy.
At the same time, the hydro-stabilized polyurethane maintained wear life better than competitive hoses, even in damp conditions and high variable rates up to 450 lbs per acre. The result is a balanced hose: precise delivery, simple handling, and durability built for real planting conditions.

UREA A DESTROYER OF AIR SEEDER HOSES
BUILT TO BE THE BEST
Built from premium virgin raw materials and shaped by real grower feedback, the U 190 was designed so the hose no longer dictates performance. Its elastic polyurethane tube absorbs fertilizer abrasion instead of wearing through, while the reinforced helix maintains shape and airflow without adding weight. The result is consistent delivery, fewer failures, and dependable operation during the most critical weeks of the season.

MATERIAL SCIENCE
Performance starts before the hose is ever built.
Kanaflex uses only high-grade, virgin raw materials, not regrind or filler-loaded compounds. Our quality ensures that every run delivers consistent strength, elasticity, and wear resistance from end to end.
That purity allows the polyurethane to maintain its physical properties season after season, resisting hardening, cracking, and premature thinning. The result is predictable performance in the field and a hose that growers can trust to behave the same on acre one as it does on acre ten thousand.

MATERIAL MATTERS
SETTING A NEW BENCH MARK
Every planting season exposes weak points: tight folds, damp mornings, high fertilizer rates, and miles of vibration across the field.
The U 190 is built so the hose stops being the issue. It installs cleanly, stays round in operation, and keeps seed and fertilizer moving exactly as intended so farmers spend less time correcting problems and more time planting. Instead of compensating for hose behavior, the machine performs as designed.
flexFLO™ U 190 vs Competitor’s Hoses
PERFORMANCE
COMPARISON SUMMARY
Moisture Resistance Flow Rate
10% higher flow than competitors ; smoother interior surface reduces flow restriction.
Performs better in humid or wet conditions; improved hydro-stabilizing properties.
Abrasion Resistance
Equal or better wear life over 9,000 acres; superior to PVC and competitive urethane hoses.
Flexibility
Easier to install, significantly more flexible, less prone to kinking, and fits complex folding mechanisms.
Accuracy
Supports more precise variable-rate fertilizer application across different soil types.
User Experience
Fewer failures when routed correctly; simpler assembly and reduced handling issues.
FLOW & PRECISION
Smooth interior walls minimize turbulence so airflow stays uniform from manifold to opener. That stability lets variable-rate prescriptions deliver the intended amount of seed and fertilizer to each zone, preventing skips and over-application.
The polymer helix design recovers without risk of exposed wire in the seed path, making it superior to all wire reinforced urethane hoses with interior corrugations.

THE DIFFERENCE
We don’t just make hoses. We engineer performance. Since 1952, Kanaflex has built its name on innovation, reliability, and integrity. The flexFLO™ U 190 continues that legacy.
