DOUBLE COATED TYPE

Use in clean rooms of semiconductor factories such as PDP, TFT, LCD that is available with a regular sprinklers

  • Stainless Steel 304
  • Zinc-plated Steel (Nut & Nipple)
  • EPDM Sealing Gasket
  • Nylon Isolating Ring
  • KFI Approved

  • Product Introduction

  • Passed strict standards and inspection by KS standard (KSD 3625) and Korea Gas Safety Corporation (KGS)
  • Insulation ring is inserted to prevent gas explosion accident due to micro current, so it is safe from the danger of gas leakage
  • Excellent gas proof and no permeability, It is possible even after abolition of a long time cock.

Easy to install.

  • Flexible and easy to bend compared to other products.
  • It is easy to install in a small space due to the freedom of banding.
  • Even if bent, the bore size does not decrease and there is no change in the gas flow rate.

The product is safe.

  • KGS AA535 Technical standards and quality control.
  • The protective coating is coated with epoxy to exhibit superior quality to other PE coatings, such as adhesion performance, liquid content, flame retardancy, and weather resistance.
  • 360 degree rotation nuts prevent hose kinks

Product management is easy.

  • The product is packed in a sturdy packing box of 30 to 500mm ~ 1200mm, making it convenient for customers to purchase the appropriate quantity.
  • Since the product is divided into foam pads between products, product damage is less when moving the product, and it is easy to load and ship the warehouse.
