CheeMuii 12FT Semi Truck Air Lines Kit — 3-in-1 Red & Blue Hoses with 7-Way Plug and Reinforced Springs

CheeMuii's 12FT 3-in-1 semi truck air lines kit combines red and blue air brake hoses, a 7-way electrical cable, gladhands and mounting hardware into a single ready-to-install assembly for trailer and tractor connections.

This complete line set is built for heavy-duty road use: double-braided red and blue hoses for service and emergency air, a zinc die-cast 7-way plug for vehicle-to-trailer power, reinforced stainless-steel spring joints at every end, aluminum gladhand handles, and a gladhand holder plus tender springs for organized storage. It meets relevant SAE and DOT specifications for fit and performance and includes replacement parts that make it compatible with many OE fittings.

What components come in this 3-in-1 CheeMuii kit?

The kit ships with everything needed to replace or upgrade a typical tractor-trailer connection. Items are pre-assembled to minimize fitting time and include both protective and functional accessories to secure lines on the road.

• One 12-foot red & blue double-braided air hose assembly (3-in-1 layout)
• One 7-way zinc die-cast electrical cable (meets SAE J560)
• Two 16" tender spring kits and one 20" tender spring kit
• One pair of gladhands plus four gladhand seals and a gladhand holder
• One pair of aluminum gladhand handles and Teflon tape for threaded fittings
• Certification notes: SAE J2394, DOT SAE J1402A, SAE J560 where applicable

How does the kit protect hoses and connectors on the road?

CheeMuii uses reinforced construction and protective joints that reduce wear at high-stress points. Every cable and air hose end is fitted with a stainless-steel spring to absorb bends and prevent kinking, extending service life under tough operating conditions.

• Stainless-steel spring joints at both ends for cushioning and anti-kink protection
• Double-braided hose body with 3-layer molding for higher burst resistance
• Aluminum gladhand handles resist cracking and aging compared with rubber grips
• Galvanized carbon steel and 304 stainless-steel components in tender spring kits

Will this kit fit my truck or trailer — what replacements does it cover?

The assembly is designed to replace common OE and aftermarket part numbers and conforms to standard connectors used across many brands. Check your existing part numbers against the compatibility list to confirm fit before purchase.

• Replaces a range of Philips, Tectran, Tremec/Sloan and Peterbilt part numbers
• Gladhands match Velvac, Tectran and Bendix replacement references
• Tender spring kits match Philips and Tectran spring part numbers
• 7-way plug meets SAE J560 for electrical compatibility

How easy is installation and maintenance for fleet or one-person shops?

The kit is packaged to cut installation time and reduce the parts you must source separately. Aluminum handles and a gladhand holder simplify routine hook-up and storage; Teflon tape is included for sealed threaded joints.

• Pre-assembled lines reduce assembly steps during replacement
• Gladhand holder secures hoses when disconnected for safe storage
• Tender springs organize and buffer lines during operation
• Included seals and tape help ensure proper leak-free joints

Who is this for: This CheeMuii 12FT 3-in-1 air lines kit is aimed at truck owners, owner-operators, repair shops and fleet maintenance teams that need a reliable, standards-compliant replacement assembly. It suits vehicles using conventional SAE-style air and 7-way electrical connections looking for reinforced hoses, longer-lasting gladhand hardware, and tidy cable management with tender springs and a gladhand holder.
