PlugSaf 12FT 3-in-1 Trailer Air Line Hose Kit — 7-Way ABS Power with Dual 3/8in Air Lines and Spiral Wrap

PlugSaf 12FT 3-in-1 Trailer Air Line Hose Kit assembly combines two 3/8" air lines and a 7-way ABS power cord in a single 12-foot spiral-wrapped cable for neat, weatherproof connections between tractors and trailers.

This integrated 3-in-1 assembly bundles the electrical power lead and both red/blue service and emergency air hoses into a single protected run. Built to SAE/DOT specifications with a zinc die-cast 7-pin plug, stainless-steel springs on hose ends, spoon-cut spiral wrap, and weather-resistant materials, it’s engineered to keep lights, brakes, and signals functioning across a wide range of conditions. The kit reduces tangling and abrasion while simplifying hookup at the rear of semi trucks, trailers, and tractors.

How does the 3-in-1 design make hookups faster and safer?

The combined cable keeps all three lines organized in one run so technicians and drivers can connect power and air with fewer entanglements or loose hoses. Color-coded handles and a tapered rubber grip speed identification and secure connections.

• Two 3/8" black air hoses for service and emergency brake circuits.
• One green ABS 7-way power line meeting SAE J2394 and SAE J560 standards.
• Spoon-cut spiral wrap prevents twisting and abrasion during turns.
• Wide red and blue handles plus tapered rubber ends for easy grip.

Will this assembly withstand harsh outdoor and cold conditions?

Yes — the materials were selected for weather resistance and low-temperature flexibility so the assembly stays functional in extreme environments. The ABS jacket, rubber hoses, and brass swivel fittings resist UV, diesel, corrosion, and cold embrittlement.

• Rated for use down to approximately -85°F (-65°C) without losing flexibility.
• Waterproof and corrosion-resistant outer jacket and fittings.
• Zinc die-cast 7-pin plug and brass swivel fittings resist rust and deformation.
• Stainless-steel springs protect hose ends from kinking and contact damage.

How durable and service-friendly is the PlugSaf trailer cable?

The assembly uses heavy-duty components designed for repeated hookups, abrasion resistance, and secure electrical contact. If you encounter issues, PlugSaf provides customer support to help with troubleshooting or replacements.

• Stainless-steel clip and spiral wrap for organized routing and impact protection.
• Zinc die-cast plug housing resists cracking and deformation under strain.
• SAE and DOT-compliant cable materials for reliable conductivity and thermal performance.
• Replaceable ends and protected connections extend service life and reduce downtime.

Who is this for: The PlugSaf 12FT 3-in-1 trailer air line hose kit is ideal for fleet managers, owner-operators, truck mechanics, and anyone who frequently couples semi trailers and tractors.
