Der zweischneidige Ring TD88 und die DIN-Verschraubungen garantieren einfache Montage und Demontage, absolute Abdichtung ohne Schweißen.
Beim Anziehen verformt sich der Ring durch den 24°-Konus der Verschraubung und erzeugt zwei Einschnitte, die perfekte Dichtigkeit gewährleisten.

UNSER SORTIMENT UMFASST

KLEMMRING AR3/C FÜR VERSCHRAUBUNGEN  DIN 2353

.

Der Ring AR3/C  wurde mit dem Ziel entwickelt, ein spezifisches und  vereinfachtes Produkt auf den Markt zu bringen.

:

Der Ring AR3/C hat an seinem axialen, dem Kopf entsprechenden Ende eine vulkanisierte Scheibe und hinten, im ringförmigen Gehäuse, einen O-Ring. Dank seiner Konstruktionsmerkmale und seiner Funktionalität gewährleistet dieser Ring eine totale Abdichtung.

RR-FORM®
TUBE FORMING SYSTEM/C 

.

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

 

BANJOS TN 111 K

Rastelli Raccordi constant research and technological innovation allowed the realization of a new version of banjos TN111: the seal system has been renewed in version TN111K-GG by displacing the seal in the inner of ring in order to avoid extrusion problems in assembly, disassembly and orientation phase and to reduce considerably the support surface necessary for a perfect seal.

.

We innovated also the seal system in the version TN111K by the introduction of the opposite engraving ring.

 

TD 88 DOUBLE-CUTTING RING

.

TD 88 ring gives the maximum reliability and security in heavy load hydraulic installations.

.

TD 88 ring’s double–edged increases the resistance to vibrations and to impulses.

.

The incision of the new edges on the tube also permits to enhance slipping resistance
