Ceramic Fiber Core Stainless Steel Wire Packing
Code prefix SCBR
Stainless wire overbraided ceramic packing uses a core of glass reinforced or stainless reinforced ceramic yarn, with an outer braid of stainless steel wire. The core carries the temperature and the sealing, the braid carries the mechanical load and protects the fiber from abrasion and extrusion. Thermal and chemical stability are good, and tensile strength is far above a plain ceramic packing. The range includes square braid and round braid constructions.

Application scope
Suitable for high-temperature sealing protection scenarios in heating furnaces, boilers, industrial furnaces, and high-temperature pipelines.
Working condition suitability and restrictions
This product is suitable for dry static high-temperature sealing conditions. 1260°C is the short-term tolerance temperature and cannot be operated continuously at this temperature condition for long periods.
The product is not suitable for conditions involving strong acid or alkali corrosion, long-term liquid immersion, high-speed medium erosion, high-frequency severe friction, or high-pressure strong impact. Such conditions can cause product wear, aging, and sealing failure.
Usage precautions
- The product contains ceramic fiber material. Cutting, processing, and installation operations generate fiber dust. During operation, maintain ventilation, wear dust-proof protective equipment, and dispose of waste in accordance with local environmental regulations.
- Use should be matched according to actual on-site working conditions, temperature, and medium. Over-temperature and over-working-condition long-term use are prohibited.
- During use, regularly inspect product condition. In case of wear, hardening, damage, or sealing failure, replace promptly.
- All technical data are for reference only. Actual performance depends on usage conditions. Users should conduct their own suitability testing and comply with relevant safety regulations and standards.
02 — Characteristics
Core and jacket do different jobs
The ceramic core seals at temperature; the stainless braid takes the load and shields the fiber from wear.
Two braid forms
Square braid for gland packing sections, round braid for rope duty and curved runs.
Higher tensile strength
The wire braid lifts the working load well above a plain ceramic packing, which suits valves with heavy stems.
Chemical and thermal stability
The combination holds up in hot gas and steam service where a bare textile would abrade or extrude.

05 — Where it is used
- Valve stem packing
- Expansion joint packing
- Furnace and kiln door seals
- Hot gas ducting joints
- Abrasion-exposed sealing
Service limits
- Wire braid conducts; do not use it where the seal must remain dielectric.
- Check chloride exposure: stainless braid is not immune to stress corrosion cracking.
- The core must match the shaft or stem clearance; an oversized section will not compress evenly.
