Name: JGD-WH Korean Standard double ball-type high-pressure rubber joints
Features:
Korean Standard double ball joints, also known as high-pressure rubber shock absorber, shock absorber pipes, shock absorbers throat, soft joints. The product is a flexible metal pipe couplings, from the inside layer, nylon cord enhanced rubber compound outer layer loose ball and set composed of metal flange. Korean standard high-pressure rubber double ball joints with high pressure, good elasticity, displacement volume, balance pipe deviation, absorb vibration and reduce noise effect, easy installation and so on. Korean Standard double ball high pressure rubber joints can be widely used for water supply drainage, recycled water, HVAC, fire, paper, pharmaceutical, petrochemical, shipping, pumps, compressors, fans and other piping systems. Common type used to transport -15 ℃ ~ 120 ℃ in air, compressed air, water, sea water, oil, acid and alkali. Special type used to transport -30 ℃ ~ 250 ℃ over the medium or oil, concentrated acid concentrated alkali, solid-state materials.
