Kooprimit Glad Hand Air Hose Kit 3/8 x 55 ft Yellow — 300 PSI, Dual-Head Chuck & Universal Gladhand

The Kooprimit Glad Hand Air Hose Kit is a heavy-duty 3/8" x 55 ft inflatable hose assembly with a universal gladhand, dual head chuck and storage bag built for semi truck roadside inflation and fleet use.

This kit bundles a long-reach, reinforced air hose with commercial-grade fittings so drivers and fleet technicians can connect directly to a semi truck air system for rapid tire inflation or auxiliary air tools. Designed for demanding road environments, the hose balances flexibility, abrasion resistance and bright visibility to simplify emergency repairs and routine maintenance around tractors and trailers.

How far will this hose reach around trailers and dual tires?

The 55-foot length gives generous coverage for most tractor-trailer configurations, allowing access to inboard and dual tire positions without moving the vehicle. Its 3/8" diameter maintains solid airflow for faster inflation while staying manageable on the deck or in a toolbox.

• 55 ft overall length to reach tires and service points on long trailers
• 3/8" bore for steady airflow suitable for large tire volumes
• Bright yellow color improves visibility during roadside work

Will this hold up under heavy commercial use and high pressure?

Yes — the Kooprimit hose is rated for a 300 PSI working pressure and a 1200 PSI burst rating, giving a large safety margin for truck tire service and pneumatic accessories. Multi-layer reinforcement and solid brass fittings resist abrasion and mechanical damage typical in fleet environments.

• 300 PSI working pressure for sustained commercial use
• 1200 PSI burst rating for safety under stress
• Brass fittings and rubber bend protectors to reduce wear at connections

How does the kit connect to a semi truck air system and tires?

The assembly includes a universal gladhand connector that mates with standard truck service ports, plus a 30° dual head chuck that fits a range of valve stems. Installation and switching between inflation and service is quick, letting drivers get tires pressurized or feed air tools directly from the truck supply.

• Universal gladhand for direct connection to trailer air systems
• 30° dual head chuck accommodates different valve stem positions
• Solid brass hardware reduces corrosion and improves sealing

How does the hose perform in extreme temperatures and storage?

The hose keeps flexibility from -40°F to 140°F, so it resists cracking in cold weather and won’t soften excessively in heat. Its low‑memory design reduces kinks and makes it easier to coil into the included storage bag for tidy placement in cab compartments or toolbox drawers.

• Operates reliably between -40°F and 140°F
• Multi-layer construction minimizes kinking and punctures
• Compact storage bag fits most truck toolboxes and cab spaces

Who is this for: The Kooprimit Glad Hand Air Hose Kit is aimed at professional truck drivers, fleet maintenance crews and owner-operators who need a durable, long-reach air line for roadside tire inflation and air-powered service. It’s especially useful for fleets that require a dependable, visible hose able to withstand frequent use, harsh weather and rough handling while remaining simple to connect to standard semi truck air systems.
