The max. permissible pressure levels for shipbuilding and industrial applications are stated on the pipe coupling’s label.
For sprinkler and water-based extinguisher systems „VdS“: Ø
33.7-88.9 mm 16 bar,
Ø 114.3 mm 12.5 bar, Ø 139.7 mm 10 bar
EPDM NBR
For water, air and solids. For gases, oils and fuels.
If there is a risk of corrosion, use
bolts and bars made from stainless
steel (CrNi). To protect couplings in
the long-term, use shrink sleeves or
protection tapes.
Note: When used in sprinkler and
water-based extinguisher systems, special flame protection
is needed. In such cases, the coupling is marked as „VdS“.

AXIAL MISALIGNMENT
≤ 1 % OD, but max. 3 mm
(Rectify greater misalignment by means of angular deflection.)
ANGULAR DEFLECTION

(Distance between pipe ends C

must be observed.)
PIPE OVALITY
≤ 2 % OD, but max. 5 mm
(Applies to two pipes of similar ovality only.)
OUTER DIAMETER DIFFERENCES
≤ 2 % OD, but max. 5 mm
The specified tolerances must not be exceeded or combined. They refer to static loads and radially rigid pipes.
A safety factor has to be included for dynamic loads such as pressure surges, external forces, etc.
(Contact manufacturer for further information.)
THE FOLLOWING INFORMATION (11-15) MUST BE OBSERVED! 
Remove burrs and clean pipe ends. Damage such as scratches, cracks, etc., or coatings such as paint, rust, etc., must be
removed from the sealing lip area.
