CheeMuii 3-in-1 Truck Air Lines Kit 12FT — Red/Blue Hoses, 7‑Way Plug & Spring Guards

CheeMuii 12FT 3-in-1 semi truck air lines kit is a complete trailer connection set that combines red/blue air hoses, a 7-way electrical cable, gladhands, springs, and mounting hardware for reliable truck-to-trailer hookups.

This 3-in-1 assembly brings together DOT- and SAE-certified air and power lines with rugged fittings and storage hardware engineered for heavy-duty commercial use. Built with double-braided air hose construction, stainless-steel spring protection, and an aluminum gladhand handle, the kit is designed to resist twisting, abrasion, and environmental wear while providing secure, industry-standard connections between tractor and trailer.

How does this kit protect lines and connectors during daily use?

The kit uses stainless-steel tender springs at both ends of the air and ABS cables to prevent kinking and abrasion where the hoses meet fittings. Those springs act as a cushion during coupling and while the vehicle is in motion, reducing strain on the hose ends and extending service life.

• Stainless-steel spring guards on both air and ABS cable ends for kink resistance
• Double-braided 3-layer air hose molding increases burst resistance
• Galvanized and 304 stainless components in tender spring kits for durability

What fittings and certifications does the CheeMuii kit include?

The package includes SAE- and DOT-compliant components suitable for heavy-truck applications: a red/blue 12-foot 3-in-1 hose, certified ABS green cable, and a zinc die-cast 7-way plug meeting SAE J560 requirements. Also included are glad hands, gladhand seals, gladhand handles, and Teflon tape to ensure correct installation and sealing.

• SAE J2394 / DOT SAE J1402A rated hose and ABS cable temperature ratings
• SAE J560 zinc die-cast 7-way electrical plug for reliable power transfer
• Gladhand seals and aluminum handle included for secure air connections

How do the tender springs, gladhand holder, and handles improve organization and serviceability?

This kit supplies three tender spring kits and a corrosion-resistant gladhand holder so your lines remain neatly stowed and protected when not in use. The aluminum gladhand handles are more resistant to cracking and UV degradation than rubber grips, making coupling and uncoupling faster and safer over time.

• Three tender spring kits to manage slack and protect cables on the dolly or frame
• Durable gladhand holder mounts securely to the trailer or truck frame
• Aluminum gladhand handles resist wear and improve grip during hookup

Will this kit fit my truck and replace common OEM parts?

It follows standard industry dimensions and connector types so it integrates with widely used tractor and trailer setups.
