Flexible Hose
Application
The flex hose has been specially designed for operating conditions in heating
and air conditioning application coils.
Each hose is made up of several components and the special 12 point double
crimping on the ferrule under strict quality control gives this hose double
security against any leakage. The special EPDM core meets a fully defined
specification. Shore hardness, resistance to aging, mechanical resistance (elasticity, tensile fracture, stretching), ability to accept chemical agents in contact
with the elastomer and non-toxic. The elastomer is not sensitive to Glycol or
water treatment products.
Hoses meet 25/50 flammability and smoke development classification
requirements of codes and specifications when tested by ASTM E 84 method.

On Installation: Avoid absolutely any tension due to stretching during the
course of tightening the connectors.
1. Install and tighten the fixed male connector (if applicable).
2. Install and tighten the union adaptor (if applicable).
3. Install and tighten the swivel nut. Use two spanners in order to screw in
the union: one to hold the hexagon of the adaptor and the other to tighten
the nut at the same time.

Temperature Rating
5°F to 230°F (-15°C to 110°C)
Important: Do not re-screw the fixed connector or adaptor after tightening the
swivel nut; this will cause tensioning of the flexible hose with a risk of rapid
deterioration at this point. On removal, take the same precautions. If the
flexible hose incorporates two fixed connectors, at least one must be installed
on a counter-part fitted with a screw connector.
Temperature rating must adhere to the control valve and pipe package valve specs when
assembled to hoses.
