KLINGERSIL® C-4430
Characteristic & main applications
Premium quality, high-pressure gasket material with outstanding stress relaxation and outstanding resistance to hot water and steam as well as to oils and hydrocarbons. Has AS4020 potable water certification. Is fire safe and AGA approved
Material
Optimum combination of synthetic and glass fibres bonded with NBR.
- In area one, the gasket material is normally suitable subject to chemical compatibility.
- In area two, the gasket materials may be suitable but a technical evaluation is recommended.
- In area three, do not install the gasket without a technical evaluation.
