* Other diameters on request.
PN - operating pressure for marine couplings (4 times safety factor).
PS - operating pressure for general industrial couplings (1.5 times the safety factor).
Use the gasket with a large gap between pipes, vacuum, external overpressure. The gasket must be ordered separately. Ordering example: Gasket for coupling RM2 219,1.
Grounding jumpers must be ordered separately.
When ordering the coupling, specify the seal material. Ordering example: Coupling RM2 219,1 N.
Install couplings in accordance with the instruction manual.
