Name: JGD-B-type threaded connection rubber joints JGD-B-type threaded connection rubber joints is from the inside layer, scraping gum enhanced multi-layer nylon cord, rubber outer layer composite tubes. Depending on the medium used rubber material is different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions. Threaded connection rubber joints Uses: JGD-B-type threaded connection rubber connector has a good overall performance, so it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial, refrigeration, sanitation, plumbing, fire, electricity, etc. infrastructure projects.
