AIGI 21SC Silicone-Core Carbon-Fibre Packing
AIGI 21SC is a low-modulus, continuous-filament carbon-fibre gland packing built around a single resilient silicone-rubber core. The elastic core gives the packing good memory, letting it absorb shaft runout and vibration while holding a tight seal.
Product Benefits
- Springs back against runout: On equipment whose shaft runs slightly out of true, ordinary packing loses its grip and starts to leak, demanding frequent gland adjustment. The silicone core in 21SC keeps the packing springing back against the shaft.
- Low-attention leakage control: It maintains excellent leakage control with minimal attention.
- Stem protection built in: A unique inorganic blocking agent and corrosion inhibitor prevent stem pitting and stop gas and liquid from penetrating the packing.
- Cool-running and shaft-friendly: With the low-modulus high-carbon fibre and double PTFE impregnation, it runs cool, seals well and protects the shaft surface.
Where It's Used
- General plant duty: 21SC serves pumps, valves, mixers and agitators across general plant duty.
- Versatile media range: It seals steam, water, oil, solvents, acids and alkalies.
- Handy stock item: That makes it a versatile stock item for maintenance teams handling mixed services.
Good to Know
- Single-core carbon build: The packing is black, combining high-carbon fibre with a single silicone rubber core and a double impregnation of PTFE lubricant.
- Demanding ratings covered: It handles hot services, substantial pump and valve pressures, brisk shaft speeds and a wide pH range.
- Multi-core upgrade: Where radial shaft motion and vibration are truly extreme, step up to the multi-core AIGI 21MSC, which carries several resilient cores for even greater recovery.
- Economical everyday choice: For typical runout and vibration, the single-core 21SC is the economical fit.
