Seal packing
Interlocking-braid gland packing made with PTFE fiber that combines high-purity graphite and chemical-resistant lubricant. Durable enough for use in chemical pumps.
This packing features excellent chemical resistance derived from characteristics of the gland packing materials.
PTFE is used as a base resin, and a proprietary chemical resistant fiber that has been combined with lubricant is used as the braid yarn.
With the interlocking-braid structure, this packing is extremely flexible, and enables uniform contact with the shaft, thus providing excellent sealability and long-term stability.
