The S.I.R.I.A. S.p.A. companywas founded in 1932. It wasspecialized in theconstruction of waterpipelines and aqueducts ingeneral. In 1980 theFERRERO family bought thecompany and changed itsname into NOVA (new) SIRIAS.r.l. and specialized in theproduction of fittings. In2012 the Companycelebrated 80 years ofhistory.

Wide Range Mechanical Couplings
Centre Sleeve
Compression Rings
Sealing Gaskets
Bolts
As the bolts are tightened, the two end rings are drawn together.This compresses the gaskets against the pipe surface thus providingan effective leak-proof sealing.
Tolerance Range
Range of different outside diameters that a single fitting can connect.

Excellent adhesion
Resistance against the “peeling” off the surface
Absence of particle migration into the water
Excellent resistance to corrosion, to mineral salts, to alkalinesubstances and to most solvents and organic acids
Highly resistant against scraping and bumping
Good electrical insulation
Self-Lubricated
Fire Resistant
Abrasion Resistance = 13 mg, Impact resistance >2 J
Our products are coated withRILSAN®NYLON 11, a polymer producedfrom a renewable raw material of plantorigin, the Ricinus Communis (Castor Oil),which grows primarily in tropical countries.
Rilsan® Fine Powders is hence athermoplastic which is not directly impactedby the variation in crude oil prices.
Rilsan is compliant with the most importantinternational norms regarding contact withpotable water (e.g. WRAS, DWGW, etc.).

Straight couplings provide a flexible mechanical connection between two spigot ends
having the same nominal bore and the same or different outside diameter.

Reducing Couplings
When the difference between the O.D. of the pipes is bigger than the gasket’s tolerancerange (30mm or 50 mm) the solution is our stepped couplings.
