China Professional Supplier NBR O-Ring Wholesale to Provence
China Professional Supplier NBR O-Ring Wholesale to Provence Detail:
Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging – often a key advantage over natural rubber.
Technical Data Sheet
| Color | Black or Color |
| Material | Nitrile(NBR) |
| Hardness(Shore A) | 65~75 |
| Temperature(℃） | -30~+120 |
| Tensile Strength(Mpa) | 14 |
| Elongation at Break(%) | 384 |
| Density(g/cm3) | 1.2 |
Application Area
Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.

I built a physical deposition chamber, for now it’s just evaporative deposition but I plan on adding a few other variants. The thin films created can be used in many ways.
The chamber still has a ton of space leftover and I have some more equipment coming so hopefully I can do more interesting things.
Sorry there’s no footage of lathing the feedthroughs, they worked nice with a cut o-ring and some heat shrink. Make sure you cut a slot down the holding screw threads to vent behind em. The 2 copper feedthroughs allow (with a center tap) 2 tungsten boats with different metals so I can avoid opening the chamber in a multi layer coating.
The pump down takes about 45 min. to get to 10e-5. I can use a small steel hemisphere with a kf40 hose on the top for use with a secondary high vacuum chamber. The shutter was aluminum flashing with some steel stuck on one side so a neodymium magnet on the outside of the bell jar could move it around without a feedthrough.
This build was really fun
I got everything from mcmaster, K.j lesker, ebay and what I already had
This did cost a bit to make:
diffusion pump- $160
mechanical pump-$140
plate- $270 (ouch!)
valves- $90
gauges- $200
misc vacuum stuff -$120
bell jar – $140 (stupid)
other stuff – maybe $100?
