STANDARD
European air couplings are heavy-duty claw couplings manufactured in compliance with DIN 3489.
OPERATION
The claw distance is standardised to 42 mm. The couplings are pushed together and rotated to form a seal. Due to the lateral and angular shape of the seal an instant force is set, which prevent pressure loss due to vibration. The head of a European air coupling is identical and exchangeable with other European air-versions.
APPLICATION
For air and water applications.
N.B.: European air couplings should never be used for steam applications
WORKING PRESSURE
10 bar / 145 psi |
|
TEMPERATURE
-30°C / -22°F up to 120°C / 248°F
Hose, coupling, assembly method and seal must be chosen in relation with the desired application and temperature range.
MATERIAL
Coupling: Galvanized steel
Seal : NBR
ASSEMBLY
Two-bolt saddle clamps
Worm drive clamps
THREADS
Male thread: DIN 2999, BSPT (not complying w/ DIN 3489)
Female thread: DIN ISO 228-1, BSP |

FEATURES
1. Claw distance: 42mm
2. LMC's EA couplings include a specially designed profiled NBR seal, the lateral and angular shape of which offers excellent compression properties. Pressure is applied as soon as the coupling is connected.
3. The serrated shank ensures perfect rigidity when assembled with saddle and worm drive clamps.
4. The LMC-Couplings brand name is marked on the top of the coupling. |
