- Are brass accessories manufactured by rmmcia suitable for potable water?
Materials used for manufacturing RM brass fittings fulfil rule UNE –EN149101 – Annex A of composition of metal materials in contact with water for human consumption, for which lead content is limited at a maximum of 3,5%. Moreover, for forged brass fittings lead content is below 2,2% according to DIN 50930-6 and according to D.M.174 of 06/04/2004.
- What pressure can support your products in working conditions?
In general, normal maximum working pressures considering temperature for brass threaded fittings are summarized in the following table:
Maximum Pressures Temperatures Sizes 30ºC 60ºC 110ºC up to 1" 25 bar 25 bar 16 bar from 1.1/4" to 2" 25 bar 16 bar 10 bar from 2.1/4" to 4" 16 bar 16 bar 10 bar
More or less severe conditions are acceptable or recommended depending on each item, the characteristics of the union, the sealing means and the tube considered. Feel free to contact us for any further clarification required (by describing the application, the fluid and the conditions of pressure and temperature).
- Is the same brass than bronze?
No, although both are alloys mainly based on copper, bronze is an alloy of copper and tin as a second main component while brass is an alloy of copper and zinc as the second main component.
- What’s the weight and dimensions of your products?
Each product has a range of dimensions named with a given reference. The information is displayed on the website and in the catalogue you can find more specifically the weight of each reference. Downloadable from the website there’s also a technical sheet for all the threaded fittings, containing a drawing with all levels. For any further data please contact us.
- What’s the difference between PEX and multilayer fittings?
PEX and multilayer fittings are of same composition and manufacturing, both for polyethylene plastic pipes, but the ones for multilayer include a PTFE joint (also a nickel plated nut). This is because flexible pipe for which is used contains an internal layer made of aluminium and joints avoid effect of electrolyse, by impeding contact of aluminium with brass from the accessory. To know more about PEX and multilayer pipes, please visit the article on our blog: PEX and multilayer.
- How do I install the fittings?
In the catalogue there is interesting information at each family of products about the installation. Also in our Youtube channel there are tutorials which explain within a few minutes how to install correctly our fittings with very practical advices.
