Offering what it calls "the latest in hose-fitting technology," Four Seasons has introduced a system for building A/C hoses in the field. It’s said to be sufficiently flexible for use on most heavy duty trucks and off-road equipment. The system is comprised of 71 fitting kits and four different hose sizes in 25-ft lengths.

There’s no need for large, expensive crimpers and dies, the company says, and no measuring is required, adding that  all a user needs is the proprietary hand crimp tool and a hose cutter.
