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
- 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.
