NORMACLAMP® - Hose Clamps
Variants
NORMACLAMP® FBS R
is a space-saving clamp. It was designed with the aim of rea-
lising the technical minimum overall height to allow its use in
difficult assembly situations.
NORMACLAMP® FBS HC
is a pre-opened version secured by a plastic retaining clip. After
slipping the clamp onto the hose, this clip can be easily removed
by hand.
NORMACLAMP® FBS MC
is a pre-opened (and, if desired, pre-positioned) clamp secured
by a small metal clip. The retaining clip for this version is remov-
ed by using pliers.
NORMACLAMP® FBS C
is a pre-opened clamp which is pre-positioned on the hose. The
retaining mechanism for this version is an integral part of the
clamp band.

NORMACLAMP® - Hose Clamps
Applications
NORMACLAMP® FBS springband clips are specially suitable for
use in applications where connections are under extreme cyclic
temperature loads:
• Coolant and heating systems
• Fuel lines
• Airducts
• Drainage of water and brine
In order to determine the correct size of clamp please proceed
as follows:
1. Slide the hose onto the spigot and measure the
Dmin. and Dmax.. (see diagram below)
2. From the Dmin. value determine the nominal diameter (Dn)
of the appropriate clamp.
Dn = Dmin.
3. Compare the Dmax. value with the stated minimum diameter
of the open clamp and select the suitable clamp size.
D0 min ≥ Dmax.
Samples can be provided on request. We shall be pleased
to discuss your specific problem or application in detail. Just
contact us.
