Zoro Select Compression Packing Seal 100 ft

This compression packing seal provides 100 feet of flexible fiberglass material designed for industrial sealing tasks. It suits maintenance teams and engineers who need a high-temperature resistant seal that conforms to uneven surfaces. The square profile and 75 lb density offer consistent performance in demanding environments. It is not intended for applications requiring adhesive-backed tapes or liquid sealant compounds.

Square 1/2 in profile fits standard packing glands

The square 1/2 inch cross-section seats directly into compatible stuffing boxes or gland assemblies without additional machining. Its flexible fiberglass construction allows the seal to adapt to irregular surface finishes, reducing the need for precise surface preparation. The material withstands continuous exposure up to 380 degrees Fahrenheit, freeing operators from frequent replacement cycles in high-heat service. It does not suit dynamic rotating shafts that require low-friction braided packing.

Supplied as 1200 inch continuous length

The single 1200 inch coil lets technicians cut exact lengths on site, eliminating waste from pre-cut short segments. No separate cutting tools or lubricants are bundled, so installers use standard workshop knives and assembly grease. The white fiberglass color provides clear visual indication of wear or contamination during routine inspection. No installation software or digital calibration aids are included or required.

Questions about this item

How long will the 75 lb density hold under continuous compression?

The 75 lb density fiberglass construction maintains seal integrity at 3,200 N/mm tensile strength, resisting permanent deformation during sustained loading.

Does the packing generate excess heat or friction during all-day operation?

Fiberglass material operates up to 1,380 degrees F without thermal breakdown, and the flexible square profile minimizes friction against uneven surfaces.

What gland dimensions are required for this 1/2 in square packing to seat correctly?

The 1/2 in square cross-section requires a matching gland width and depth; the 100 ft coil allows cutting exact lengths for any stuffing box size.
