10 pieces rubber cork M10 30mm x 10mm x 4mm

Description

Washers have a round hole and are also called washers, for example. These washers are preferably used together with hexagon head screws, machine screws, nuts, threaded rods, self-locking nuts, spring washers and body washers for Allen applications in steel and wood construction, as well as protective elements for surfaces.
The washers are made of high quality materials and stamped by hand.
All seals are 4mm thick.

- Material: rubber cork
- Thickness: 4 mm
- available in different sizes:
M6 outer diameter of 22.00mm and inner diameter of 7.00mm
M8 outer diameter of 25.00mm and inner diameter of 9.00mm
M10 outer diameter of 30.00mm and inner diameter of 10.00mm
M12 outer diameter of 35.00mm and inner diameter of 14.00mm
M14 outer diameter of 42.00mm and inner diameter of 15.00mm
M16 outer diameter of 46.00mm and inner diameter of 17.00mm

Large washers like these serve to better distribute the force and thus prevent damage to the work by tearing, tearing or digging into the material through the screw.

- 100% accurate and clean processed
- These seals are manufactured according to din 7715 with tolerance class P2.

Manufactured in our own workshop.


- Please note that shipping to packing stations is not possible.
The cork granulate rubber mixture is characterized by good acid and weather resistance as well as limited resistance to ozone and alkalis. Compared to other sealing sheets, rubber cork is abrasion-resistant due to its composition. The material also has a high density and mechanical strength, which makes it possible to isolate airborne and acoustic noise. For this reason, the material is used as a vibration-isolating sealing material, among other things for impact sound insulation. Another advantage includes the compressive strength and dimensional stability of the material.
The advantages and material properties at a glance
Seals and rollers made of rubber cork are characterized by the following advantages:

Good acid resistance
Good weather resistance
Conditional resistance to ozone and alkalis
Abrasion and pressure resistant
thermally insulating
Sound and heat insulating
In summary, rubber cork is resistant to various thermal and mechanical loads. As a result, the sealing material is suitable as a soundproofing and thermally insulating sealing material for a wide variety of purposes.

The mechanical characteristics of NBR include high abrasion resistance, good tensile and tear strength and low compression set. With regard to the thermal properties, the elastomer is temperature-resistant between a maximum of -30 °C and +120 °C - depending on the specific composition and the proportion of acrylonitrile.
NBR in standard material quality has a medium acrylonitrile content in order to cover the widest possible range of applications. As a standard material, the material shows good mechanical values, including good resistance to mineral oil-based lubricating oils and greases and to water up to around +80° C.
The properties of NBR as a sealing material:
swelling resistance
elasticity
cold flexibility
gas permeability
and compression set
If the acrylonitrile content is rather low, the resistance to oils and fuels is reduced. On the other hand, the material is significantly more flexible at low temperatures. A high proportion of acrylonitrile impairs mechanical behavior at low temperatures, but improves resistance to oils and fuels. In general, the temperature resistance of NBR is lower than that of EPDM.
In general, NBR is impermeable to gas and air, which is why the material is well suited for use in industry and in gas supply.

As a rule, seals and other components made of silicone are suitable for use in environments with a temperature range between -60°C and +210°C.
In addition, the sealing material is weatherproof due to its resistance to ozone and UV radiation.
Due to its high temperature resistance and good mechanical properties, silicone is an excellent material for seals and sealing profiles.
Silicone seals have excellent resistance to ozone, oxidation, ultraviolet light, cosmic and ionizing radiation, and weathering in general.

silicone is:

biocompatible and physiologically harmless
temperature and heat resistant
ozone and UV resistant
food safe
FDA compliant
Approved for drinking water (according to WRAS)
