Sterling Seal OR90BLKBUN113X100 113 BUNA/NBR O-Ring, Nitrile, 90 Durometer Hardness (Pack of 100): Industrial & Scientific. Sterling Seal OR90BLKBUN113X100 113 BUNA/NBR O-Ring, Nitrile, 90 Durometer Hardness (Pack of 100): Industrial & Scientific. Sterling Seal & Supply Buna nitrile O-Rings are Recommended for Use with crude oil, gasoline, propane, petroleum oils and water . Sterling Seal & Supply Buna O-Rings have high extrusion resistance making them suitable for very high pressure static applications . 90 durometer nitrile O-Rings resist wear, feature good mechanical properties in comparison to other elastomers and are built to withstand fuel, oil and other fluids . Operating temperature: -40° to +250F° . 9/16ID nominal x  3/4OD nominal x  3/32CS nominal . Sterling Seal & Supply Buna-n are the most common and the simplest types of seal with an excellent sealing property and durability Recommended for use with crude oil, gasoline, propane, petroleum oils and water Tube fittings and adapters are supplied with 0 durometer hard nitrile (Buna-N) these are well suited for most industrial hydraulic and pneumatic systems They have high extrusion resistance making them suitable for very high pressure static applications Nitrile are used as a face to face gasket Style seal or as a shaft seal, and allow both rotary and linear movement Use 0 durometer hard for applications with 500 psi or higher pressures Like their 70 durometer counterpart, 0 durometer nitrile are comprised of a Multi-Purpose rubber compound, Acrylonitrile and butadiene that performs well in most environments As with other nitrile , 0 durometer nitrile resist wear, feature good mechanical properties in Comparison to other elastomers and are built to withstand fuel, oil and other fluids Operating temperature range is -0° to +50F° the 0 durometer hardness of the in this Kit also makes them more resistant to extrusion while reducing their flexibility in low temperatures . . .

درباره ما

پیشرفت سریع فنّاوری اطلاعات، تأثیرگذاری شگرف آن در حوزه‌های یادگیری و ترکیب آن با نظریه‌های تعلیم و تربیت، حوزه‌ای جدید و میان‌رشته‌ای به نام «یادگیری الکترونیکی» را پدید آورده است. در ایران نیز از سال ۱۳۸۶ جمعی از متخصصان علوم تربیتی و فنّاوری اطلاعات با برگزاری کنفرانس‌های سالیانه‌ی «یادگیری الکترونیکی» بر آن شدند تا با ایجاد انجمنی علمی، محیطی منسجم و هم‌افزا را برای توسعه‌ی این عرصه‌ی جدید در کشور پدید آوردند. سرانجام این تلاش در سال ۱۳۹۰ به بار نشست و «انجمن یادگیری الکترونیکی ایران» با مجوّز کمیسیون انجمنهای علمی کشور تأسیس شد.
