Dazakoot 15FT Coiled Air Brake Short Tail with 2×12in Leads — Reinforced Nylon, 1/2in Swivel

This coiled air hose combines a compact 15-foot coiled body with dual 12-inch straight leads to make connecting and disconnecting the tractor and trailer fast and dependable. Constructed from reinforced nylon, fitted with a 1/2" swivel brass fitting and spring guards, this assembly meets industry SAE and DOT standards and is sized to work as a drop-in replacement for popular part numbers. It’s intended for commercial truck and bus air brake, instrumentation and accessory systems where durability and easy routing in tight spaces matter.

How does the coiled short tail improve installation in tight spaces?

The coil design retracts when slack is needed and expands to provide full length under load, so routing around chassis components or through telescoping fifth-wheel areas is simpler. Anti-kink geometry prevents folds that can interrupt airflow, making it easier to fit in cramped or moving zones without repeated adjustments.

• 15-foot coiled main body compresses for compact routing.
• Two 12" straight lead ends for easy coupling to fittings.
• Spring guards at connection points reduce strain and chafing.

What materials and fittings ensure long-term reliability?

The hose uses high-strength nylon tubing reinforced for pressure retention and abrasion resistance, combined with a 1/2" swivel brass fitting that resists corrosion and allows smooth connection. Spring joints on the red and blue lines protect the coupling areas from bending fatigue, extending the service life under constant flex.

• Reinforced nylon tubing for durability and pressure stability.
• 1/2" swivel brass fitting for secure tractor-end connections.
• Spring guards prevent kinks and wear where hoses bend most.

Which standards and part numbers does it replace or comply with?

This assembly is manufactured to meet common industry requirements such as SAE J844 A and DOT FMVSS 106, ensuring compatibility with most commercial vehicle air brake systems. It’s also specified as a replacement for a range of existing lines, simplifying maintenance and parts sourcing for fleets and independent technicians.

• Meets or exceeds SAE J844 A hose requirements.
• Complies with DOT FMVSS 106 air brake standards.
• Cross-references: Tectran 17215, Phillips 11-315, Tremec Sloan 451036N.

How does the design make day-to-day use easier for drivers and shops?

Quick coupling and uncoupling are achieved by color-coded red and blue lines with large-diameter profiles, while the anti-kink and spring-guarded ends reduce downtime for replacements and repairs. The lightweight but economical construction balances cost-effectiveness with the needs of high-use commercial environments.

• Large red and blue lines speed identification during hook-up.
• Lightweight design eases handling without sacrificing strength.
• Durable construction lowers the frequency of field replacements.

Who is this for: technicians, fleet maintenance teams and owner-operators who need a reliable, compact air brake coiled hose that installs quickly and withstands the movement and abrasion typical on heavy trucks and buses. If you’re replacing worn OEM lines, outfitting a new trailer set, or stocking cost-effective service parts, this Dazakoot assembly offers industry-compliant fittings and a space-saving coiled profile for straightforward integration.
