Rubber plugs and sockets, what kind of difference

Market EPDM rubber seals, EPDM rubber inner layer, the outer layer of the center of the ordinary natural rubber ply, so that not only did not have a great impact in the life obtained by the temperature of the rubber joints have a great impact ! Here, you how to analyze the differences are several ways of ordinary natural rubber seals rubber joints! Concept of color, carefully observe the color of the rubber ball, a lot of fakes are usually very dark, through the use of low-end, low-quality rubber, paint, to avoid the experience to see through.
Most of them in the factory grinding departure black shoe oily, it looks black light. But the real EPDM seals manufacturing, pure color, light color Shen. Not very bright or very dark. Taste, in fact, is the best method of analysis, the inside of the rubber component containing rubber alkenyl normal circumstances, irritating odor. However, to ethylene-propylene-diene rubber (EPDM) rubber is a polymer of ethylene, propylene, and the height of the filler composition, therefore, after the vulcanization of ethylene propylene diene monomer rubber (EPDM) rubber filled, but not the ordinary rubber thorn The taste of the nose, but the color of the substituted aromatic taste. As long as you pay attention, it is not difficult to uncertainty mine genuine. Touch, you look at the ball of rubber friction contact point, it will be a smooth feel authentic EPDM rubber texture delicate and expensive. Production of rubber seals, smooth surface, especially in connection to feel ordinary rubber touch much weaker, it is stroking rough skin.hydraulic adaptors
Rubber seals by two flanges and a ball than the rubber ball forged steel, carbon steel flanges, forged steel two processes: Hard Mode and air mode inflatable better choice the YATIN own actual situation, when You have to use. Note welfare want to make a lot of demand, it is recommended to use stainless steel gas mode is relatively high, it is recommended that the use of forged dinghy. A few years ago a hard cast steel fashion do not ask for much, so can be used. Through a simple synthesis, after the introduction of the use of time, you know what kind of easy to operate.hydraulic testing machine
