- Aseptic
- Aseptic seal for fluids, creamy substances or other foods and beverages for nourishment, characterised for being expressly studied so to prevent the possibility of infiltration or stagnation of the product inside or along the circumference of the seal, in order to avoid the risk of possible formations of undesired bacterial flora that can dangerously grow in the grooves of the seals.

- Unsuitable for animal oil and peanut oil.
- Nitrile (NBR)
-
Nitrile rubber is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Also known as NBR (Nitrile Butadiene Rubber) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene).
Temperature Range:-30ºC to 108ºC
Properties:
- Outstanding resistant to petroleum oils and aromatic hydrocarbons.
- Excellent resistant to mineral oils, vegetable oils and many acids.
- Good elongation properties, resilience, tensile, abrasion and compression set.
- Poor resistance to attack by: UV, nitro hydrocarbons, ketones, esters and aldehydes.
Detailed usage:
- Suitable for animal oil, ammonical liquor, argon, beer, butter, cane sugar, citric acid, heluim, lard, mercury, milk, nitrogen, olive oil, peanut oil, seawater, soap solution, sodium chloride, sodium sulfate, water, wine and whisky.
- Can also be used for citric acid, iodine, oxigen, salicyclic acid, sulphurous acid and vinegar.
- May not be used for bleach, citric acid, chloroform, ozone, steam, sulphur and sulphur dioxide.
- Unsuitable for formic acid and oleic acid.
- PED
- The Pressure Equipment Directive (97/23/EC) was adopted by the European Parliament and the European Council in May 1997. It has initially come into force on 29 November 1999. From 29 May 2002 the pressure equipment directive is obligatory throughout the EU. The directive provides, together with the directives related to simple pressure vessels (2009/105/EC), transportable pressure equipment (99/36/EC) and Aerosol Dispensers (75/324/EEC), for an adequate legislative framework on European level for equipment subject to a pressure hazard. Pressure Equipment Directive overview
- Rubber
-
Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis.
Temperature Range:-35ºC to 90°C
Properties:
- Excellent compression set and bonding capabilities to metal substrate.
- High tensile strength.
- Good resilience, abrasion and tear resistance.
- Good friction and vibration dampening characteristics.
- Poor resistance to attack by: petroleum oils, UV, aromatic hydrocarbons, ketones, esters and aldehydes.
Detailed usage:
- Suitable for argon, beer, citric acid, formic acid, iodine, mercury, nitrogen, salicyclic acid, seawater, sodium chloride, sulphurous acid, vinegar and water
- Can also be used for heluim, lard, milk, soap solution and sodium sulfate
- May not be used for bleach, butter, chloroform, oleic acid, olive oil, ozone and peanut oil
- Unsuitable for animal oil, ammonical liquor, cane sugar, oxigen, steam, sulphur, sulphur dioxide, wine and whisky
- Rust
-
Some of the most common reasons that will make stainless steel to bleed a stain (rust) are:
- Use of ferrous tools.
- Traces of iron smeared on the surface from machining equipment.
- Fittings left in installer's toolbox.
- Exposure to chemical substances like bleach or other chlorides.
Passivation or electropolishing is know to be very helpful in preventing no-catalyst corrosion and also preventing metals from going dull.
Stainless steel 316L is an extra low carbon grade of 316 and because it also contains molybdenum is widely used due high resistance to corrosion.
- Silicone (VQM)
-
Silicone is a semi-organic elastomer that utilizes a flexible siloxane backbone rather than a carbon backbone like many other elastomers and has very low glass transition temperatures.
Temperature Range:-59ºC to 232°C
Properties:
- Outstanding resistance to compression set, retention of flexibility and exposure to extremes of temperature.
- Excellent resistance to UV and moisture.
- Very clean, low odor and taste.
- Typically not good for dynamic seals due to friction properties and poor abrasion resistance.
Detailed usage:
- Suitable for argon, beer, cane sugar, citric acid, heluim, milk, nitrogen, olive oil, oxigen, ozone, peanut oil, seawater, soap solution, sodium chloride, sodium sulfate, vinegar, water, wine and whisky.
- Can also be used for animal oil, ammonical liquor, butter, formic acid, lard and sulphur dioxide.
- May not be used for bleach, chloroform, oleic acid and sulphurous acid.
- Unsuitable for iodine, mercury, salicyclic acid, steam and sulphur.
- Teflon (PTFE)
-
Polytetrafluoroethylene is hydrophobic, so neither water and water-containing substances are wet by PTFE.
It has one of the lowest coefficients of friction against any solid
- Viton (FKM)
- Fluoroelastomer, special purpose fluorocarbon-based synthetic rubber.
Temperature Range:-15ºC to 199°C
Properties:
- Excellent UV, petroleum oils, chemical and heat resistance.
- Good mechanical properties and compression set resistance.
- Low gas permeability and self-extinguishing properties.
- Poor resistance to hot water, steam, polar solvents, low molecular weight esters and ethers, hot hydrofluoric or chlorosulfonic acids. Poor low temperature flexibility.
Detailed usage:
- Suitable for animal oil, argon, beer, butter, cane sugar, chloroform, citric acid, heluim, iodine, lard, mercury, milk, nitrogen, olive oil, oxigen, ozone, peanut oil, salicyclic acid, soap solution, sodium chloride, sodium sulfate, sulphurous acid, vinegar, wine and whisky
- Can also be used for bleach, oleic acid, steam and water
- May not be used for ammonical liquor, sulphur and sulphur dioxide.
