Non-Asbestos Gland Packing
Up to 260–450°C
Main applications
non-asbestos gland packing that stops valve leakage completely
Key Features
Stops valve gland leakage completely
Packing made for valve stuffing boxes — sealing the stems of rotating and reciprocating valves
Asbestos-free
Contains no asbestos — compliant with industrial safety regulations and protecting worker health
Durable at temperature and pressure
Heat-resistant fiber based — maintaining sealing performance long term in hot, high-pressure valve service
A choice of chemically resistant materials
PTFE, graphite, carbonised fiber and others — selected for acid, alkali or solvent service
Standard sizes, direct replacement
Supplied to standard valve gland sizes — an immediate asbestos-free replacement for existing packing

Notes
- ※Existing asbestos packing can be replaced directly in the same section size — tell us the existing specification and we will match it.
- ※Choosing the material: PTFE for chemical resistance, graphite for heat and pressure, aramid for abrasion, carbonised fiber for high pressure — tell us the fluid, temperature and pressure and we will recommend.
