Getting Started with TruBlu

Cautions/Safety

TruBlu hoses are intended for use by professionally trained HVAC technicians. TruBlu hoses are not
intended for pressure. They are designed for vacuum only the same as your vacuum pump. Pressurizing
a vacuum hose could cause displacement of the O-ring seal which leads to pressure loss, refrigerant loss,
and could cause bodily injury.
Always wear gloves and goggles and other required PPE when
working on or around refrigerants.

Product Use

TruBlu hoses use KF or Quick Flange fittings. KF fittings allow for one hose to be used in multiple applications
with a variety of end configurations. The hose can also be connected to a tee 'T' or wye 'Y' fitting to further
expand the system flexibility. KF fittings use a taper lock flange and clamp connection that is sealed with
an O-ring. Unlike typical KF fittings used in industrial vacuum service, TruBlu hoses have the centering ring
built into the flange to prevent the centering O-ring from falling on the ground when end changing fittings
in the field (patent pending).
Once an end fitting is installed on a hose there is no need to remove it unless you want to change the hose
configuration. Leaving the fittings on the hoses prevents damage to the O-rings and protects the flanges
from damage. A plastic cap is included with each end connection, and it is advised that end connections that
are not in use the flange is capped. This will prevent the sealing surface from getting scratched, nicked, or
marred. The flat surface is the sealing surface, and care should be taken that it is not damaged.
KF Fitting with Integrated O-Ring Hose-end Flange Face
There are two types of clamps provided in your kit, a stainless low-profile type (p. 6 left) and a larger
aluminum clamp (p.6 right). These are standard KF style clamps. Clamp wing nuts only need to be finger
tight. The connection is actually self-sealing under vacuum. The low-profile clamp is intended to be used on
the hose end that connects to the Schrader core removal tool and intern the equipment, the larger clamps
are intended to be used where space is not limited.
