So far welding nipples often have been employed in metallurgical industry and in construction of cranes and elevators, off-shore facilities and heavy-duty farming machines, but now RR-FORM® system replaces welding with a faster and more reliable method. RR-FORM® SYSTEM AND AR3-FORM® GUARANTEES • EASY ASSEMBLING: the new sealing ring AR3-FORM® eliminates time-consuming operations to make sure that the ring cuts into the tube • ABSOLUTE SEALING: new sealing ring AR3-FORM® assures perfect tightness by the elastometric gasket that fills the space between tube and 24°-taper during the clamping procedure • AUTOMATIC TIGHTENING LIMIT: contact between AR3-FORM® ring and fitting body because of the nut tightening effect compels the operator to stop tightening • CUTTING RING FITTINGS INTERCHANGEABILITY: new AR3-FORM® rings perfectly interchange like all the other sealing rings with one cutting edge or two cutting edges used on 24° tapered fittings DIN 2353 /ISO 8434-1
