Rubber Metal Gaskets

Rubber bellows manufacturer in Germany, Europe, UK – Horiaki

We manufacture Black Rubber Metal Gaskets for the purposes where natural media like Water, Closed Loop Water Arrangements, SolutedLyes at max 50% conc. and mx 80% have to be sealed.

All our products including Rubber Gaskets are in compliance to world standrads like KTW , W270,DGVW, WRAS ETC are standardized and are only manufactured with SYNTHETIC Rubber SUCH AS EPDM, NBR, SILICON,FKM,FFKM having hardness of DIN 53505, Shore A to make them resistant to water, seawater, pond water, closed loop water up to 90°C and also against alkalines up to some extend like 50% NaOH at 50o.
For effective functioning at even high temperature range of approx. +80°C and for short-term up to +90°C, HoriakiIndia Pvt. Ltd.  Rubber Metal Gaskets Water Lines, Rubber Metal Gasket DGVW etc. have the density DIN 53479, g/cm3 1.384.Based on our own test facilities Horiaki India Pvt. Ltd. manufactured rubber metal gaskets are certified resistant even against natural lighting, weather and ozone. Limited only by the natural properties of vulcanized rubber our rubber metal Gaskets are not resistant against fuel, mineral oils, acids and gases.

Materials: NR=Natural Rubber(SMR)
Application Field: Water, Closed Loop Water Arrangements, Soluted Lyes at max 50% conc. and mx 80%
Color: Black
Hardness: DIN 53505, Shore A 60-80 +/-5
Density: DIN 53479, g/cm3 1.384
Temperature: approx. +80°C, short-term up to +90°C
Certificates: Approval of own test facility.

Chemical resistance :

• Vulcanisates of natural rubber (NR) are resistant against: water, seawater, pond water, closed loop water up to 90°C
• Partly against alkalines, 50% NaOH at 50°C
• Sufficient resistant against natural lighting, weather and ozone
• Vulcanisates of natural rubber (NR) are not resistant against:fuel, mineral oils, acids and gases

Application field : The application of NR-vulcanisates is possible where natural media have to be sealed. Temperatures higher than 90°C have to be avoided.

Function and durability : The performance and life of Horiaki gaskets depend in large measure on proper storage and fitting, factors beyond the manufactor’s control.We can, however, vouch for the excellent quality of our products.With this in mind, please also observe our installation instructions.

• Rubber-Metal-Gaskets – Safe sealing of gases and liquids
• Safe sealing of water, gas, air, acids, alkalis and hydrocarbons with low sealing forces at temperatures up to 200°C, depending on the elastomer type.
• Rubber-metal-gaskets are used where safe sealing of conventional up to special industrial media such as gases and liquids are required under usual installation conditions like temperatures, pressures and forces
• Suitable for all flange materials
• A flange connection has to be always treated as a coherent system, because the sealing functions is determined by the interaction of individual elements including flanges, gaskets and screws
