For over 15 years JUAN RONCAGLIA SAIC Molded rubber is present with its rubber seals -gaskets epdm Peroxid cured- developed especially for use in the chlorine producing equipment. Chlorine, and more its gases, are highly aggressive with the compounds of rubber. Therefore, in our laboratory has developed a compound that turns out to be more resistant to attack. Our gaskets are used by equipment manufacturers as a replacement for chlorine and chlorine producers. We have spare parts for equipment Ionics, Uhdenora, Alfa Laval and Eltech. We supply the Argentine market and export to the U.S., countries in Central America, South America and Oceania Molded rubbers. The joints are carefully packed, to enable so, the immediate placement of equipment.

Shorter set-up time. Very fast change of inner coil diameter. The sleeves can be mounted with working installation. Change the I.D. coil en minutes.

Safer operation. Safer operation comparing to steel heavies reel jaws.

Mandrel protection. Addicional advantage, RONCAGLIA (R) rubber sleeves protects mandrel mechanisms.

Check valves are used in the installation of hydraulic systems to let liquids flow in one direction but prevent them from flowing in the opposite direction. In many applications these valves - made of steel or cast iron - which are heavy as well as costly and need constant maintenance, are replaced by the so-called Duck Bill Check Valves.

RONCAGLIA(R) Duck Bill Check Valves are manufactured entirely in rubber, using compounds which are highly resistant to different environments.

They weigh 10% or less than regular valves, thus making them more economical, easy to transport, easy to mount and maintenance free.

Due to their convenient design, they are not likely to get stuck should strange elements be swept by the fuids.

They are manufactures from 2 inches up 55 inches diameter.

They do not need external energy to operate. They are easily mounted at the end line of sewers or storm sewers. RONCAGLIA exports Check valves all over the world.Rubber products manufacturers

The most important steel manufacture argentine company has employed the RONCAGLIA® SLEEVE for steel sheets coils winder and de-winder mandrels, since more than 30 years in his five plants.
The use of this rubber sleeve, allows:

1-to protect the steel sheet, the defects caused by the metallic mandrel, on the first loops. When a metallic mandrel is opened against the thin metallic sheets, usually a typical mark has been place, on the first loops, these loops have been rejected.

2-to replace metallic supplements for different I.D. coils.    When it is necessary to produce coils with different internal diameters, the use of Roncaglia® rubber sleeve, instead of such heavy’s metallic supplements, assures faster and safer installation.

3-to protect mechanical mandrel systems. When you use Roncaglia® rubber sleeve, you have an additional advantage; you are protecting the mandrel mechanisms from dust, which can affect the normal operation.
