Overview

CheeMuii 12FT 3-in-1 Air Lines Kit is designed to support semi trucks and trailers with a versatile, ready-to-install package. It combines air lines, protective springs, and a durable gladhands system, built to withstand daily highway use while remaining straightforward to set up. The goal is to help fleets and drivers connect reliably without complicating maintenance routines.

What’s included

  • 12 ft 3-in-1 air lines kit
  • Two 16 in tender spring kits
  • One 16 in single tender spring kit
  • Pair of glad hands
  • Pair of gladhand handles
  • Gladhand holder
  • Four gladhand seals
  • Teflon tape

Key benefits

  • Both ends feature stainless steel springs that cushion and protect wiring and hoses during routing and installation.
  • Aluminum gladhand handles replace aging rubber grips, providing a durable, long-lasting touch under tough working conditions.
  • Red and blue air lines use a double-braided design with a three-layer molding process for higher burst resistance and twist protection.
  • The 7-way electrical cable uses a zinc die-cast plug to efficiently transfer power, meeting SAE J560 testing.
  • A dedicated gladhand holder and spring-equipped clamps help keep lines organized and protected in mobile environments.

Real-world use scenarios include routine trailer hookups, on-site inspections, and road-ready maintenance where quick, secure connections matter. The tender springs act as buffers during movement, while the protective springs reduce wear on hoses and ABS lines, contributing to a longer service life.

Specifications and certifications

Certification references include SAE J2394, SAE J560, and DOT SAE J1402A, underscoring compliance with common heavy-duty standards. The kit’s integrated design aims for straightforward installation and dependable operation in fluctuating temperatures and demanding duties.
