* All data are 1.5mm thickness typical value.
Innovative technology, LEAKBLOK® , absolutely distinguished from the traditional way of calendar roll production.
It specially invented with environmentally friendly solvent free process.
Compare with previous product, it shows strong durability and superior at low seating stress.
Suitable for use steam and clean line, excellent protection of fluid contamination.
Warning
- Not available with max. temperature & pressure at the same time.
- Guide line only, if outside this range contact us.
- Do not re-use gaskets unless this is specifically indicated.
- Do not use gasket compounds with gasket as this will adversely affect performance.
- Please consult with Khong Lieng for application of steam & explosive gas line especially.
