18 Years Factory offer NBR O-Ring for El Salvador Manufacturer 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 |

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.

Here are my first impressions of the New PowerSpec 3D Pro 3D Printer from Micro Center. PowerSpec is Micro Center’s house brand computer. As of recently, they’ve begun offering a couple of economically priced 3D printers based on the open source MakerBot Replicator 1 dual plans. This is their second generation model that comes with an acrylic enclosure to help trap heat in the build box and mitigate warping. The frame seems to be steel with some sort of expanded PVC paneling to enclose the back, bottom, and sides. The model I picked up today is loaded with PowerSpec’s own firmware, version 1.2. There are a number of tools in the utilities panel I have not seen before, including a dangerous-looking eeprom menu, apparently for some on-board firmware tweaks. The firmware is based on MakerBot’s Rep 1 firmware so instead of .GCODE, you feed it .X3G files. That means you can use MakerWare for preparing your files instead of ReplicatorG if you prefer, as I do.
There are color-changing LED’s among the bells and whistles too, which shift hue as the build plate and extruders heat. I asked at Micro Center about buying parts for repairs and was informed that I can order everything I might need from MakerBot. I’m more than a little skeptical of that since I spotted a couple of tiny PTFE tubes in the spare parts bag. These are not part of the typical MakerBot extruder, but are what you find inside the cheap Chinese extruders on other Replicator 1 knock-offs like the Flash Forge or Wanhao. The heated build plate looks like 1/4″ glass and comes covered with a sheet of kapton tape. 10 minutes into working with it, this printer seems like a worthwhile piece of equipment for $1000.
