Universal Step Coupling DN40 to DN400 PN10/16
AQUA STEP COUPLING is a range of universal straight couplings, step couplings
and flange adaptors for cast iron, ductile iron, steel, uPVC and asbestos cement
pipes. Step couplings are easy to mount due to the anti-friction coated bolts and nuts
and the possibility of up to ±4° angular deflection. The stainless steel bolts and nuts
and the high quality coating offer a durable corrosion protection.
Standards:
· Designed according to EN 14525
Features:
· ±4° angular deflection
· Approved EPDM gasket
· The bolts and nuts are anti-friction coated to offer easy tightening and to
prevent galling
· The bolt ends are protected with plastic caps
· The moulded ribs in the gasket absorb minor imperfections in the pipe
· Versatile design tolerances typical 26 mm to cover all pipe materials
· Fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN
14901, GSK approved.
