F lexible Hose C onnectors
MECHANICAL
SPECIFICATIONS
These hoses have been specially designed for operating conditions in
heating and air conditioning, the elastomer is not sensitive to Glycol or water
treatment products.
Each hose is made up of several quality components and the special
crimping on the ferrule under strict quality control gives this hose security against
any leakage.
The special EPDM core meets a fully dened specication: Shore
hardness, resistance to ageing, mechanical resistance (elasticity, tensile fracture,
stretching), ability to accept chemical agents in contact with the elastomer and
non-toxic. ASTM Fire rated hoses meet 25/50 ammability and smoke
development classication requirements of codes and specications when tested
by ASTM E 84 method.
HOSES ARE DESIGNED FOR HYDRONIC HEATING/COOLING, NOT FOR GAS.

1. ON INSTALLATION : Avoid absolutely any tension
due to stretching, twisting or torsion during the course of
tightening the connectors.
A. Install and tighten the xed male connector (if
applicable)
B. Install and tighten the union adaptor (if applicable)
C. Install and tighten the swivel nut
Use two spanners in order to screw in the union: One to
hold the hexagon of the adaptor. The other to tighten
the nut at the same time.
IMPORTANT - Do not re-screw the xed connector or
adaptor after tightening of the swivel nut; this will cause
tensioning of the exible with a risk of rapid deterioration
at this point. On removal, take the same precautions. If
the exible incorporates two xed connectors, at least
one must be installed on a counter-part tted with a
screw connector.

COMPLETE DETAILS. WARNING: FAILURE TO
FOLLOW THE INSTALLATION & OPERATION
INSTRUCTIONS COULD RESULT IN IMPROPER
INSTALLATION.
