I usually try to keep pace
with industry news, and when encountering something out of the ordinary,
it's usually a product that I have read about months in advance. Today’s
discovery would be different.
While servicing an a/c system on a local transit bus, I stumbled across a
new type of refrigerant hose fitting, which was unique because it lacked
the standard Beadlock style crimp collar. The collar looked more like the
thin band clamp that you would expect to find on the boot of a CV shaft.
The installed a/c system was manufactured by Trans/Air (www.transairmfg.com), and the hose was
made by Aeroquip®, but that’s about all I knew at that point. So, I
grabbed my digital camera, got a couple of shots, and began working the
phone. As someone who specializes in HD a/c service, I knew that I would
end up seeing this fitting again, and wanted the information and tools to
service it. I wondered, could this be the solution to all of those leaky
discharge fittings that we have seen in recent years?
Above: New A/C refrigerant hose,
fitting, clamp and pliers system from Aeroquip is targeted to high end
applications. It’s advantage is that no external power, other than a
human hand,
is needed to make seal connection.
Trans/Air
confirmed that, in fact, the fitting, hose and clamps are all part of a
new Aeroquip system called E-Z Clip™. For Trans/Air, this premium
product is a customer-specified option.

for a #12 system. Assembly is accomplished in 7 steps: 1. Cut the hose; 2.
Slip on two clips; 3. Oil the fitting’s nipple (this must be done); 4.
Insert nipple into hose; 5. Snap on the cage; 6. Slide the clips; and 7.
Close the clips (with the FT 1357 Pliers).
A phone call was made to
Aeroquip, and they sent me out a copy of their E-Z Clip System brochure,
#JA869. As part of the overall system, there are at least 34 fittings by
my count, covering both R-12 and R-134a. It has been designed to work only
with Aeroquip GH 134 (4 layer) hose. The hose, fittings, cages and slide
clips cover sizes 6 through 12. A special pair of pliers, part number
FT-1357, is all that’s needed for assembly/ disassembly. Mystery solved!
Remember, you saw it first in Cool Profit$! $$$
