White fiberglass compression packing seal in round coil form

Zoro Select

Zoro Select Compression Packing Seal 1200" L

SKU CH-680G-B90Y6

Compression packing seal in a 100 ft roll of fiberglass material rated to 1,380 °F with chemical resistance and flexible conformability

  • Handles extreme heat up to 1,380 °F
  • Flexible fibre-glass conforms to uneven surfaces
  • Chemical-resistant material protects against corrosive fluids
  • 100 ft roll provides ample length for large jobs
  • High 3,200 N/mm tensile strength resists blow-out

100 ft Fiberglass Compression Seal

The Zoro Select compression packing seal provides 100 feet of continuous fiberglass material for industrial sealing tasks. Its round profile and 1/2 inch thickness suit flange and valve packing applications. The white seal resists chemicals and handles temperatures up to 1380 degrees F. Maintenance teams and plant engineers use it to create reliable gaskets on uneven surfaces.

Thermal Performance and Power

The fiberglass construction withstands continuous exposure to 1380 degrees F without degrading. Flexible strands conform to irregular mating surfaces to maintain a tight seal under thermal cycling. No external power or cooling is required for the material to perform its sealing function. Chemical resistance prevents breakdown when exposed to aggressive fluids at elevated temperatures.

Flexible Conformity and Density

A density of 75 lb per cubic foot gives the packing body enough substance to fill gaps while staying pliable. The round edge shape helps the seal seat evenly in stuffing boxes and gland followers. Tensile strength of 3200 N/mm resists extrusion under pressure. These properties let installers cut custom lengths that adapt to worn or misaligned equipment without additional tooling.

Questions about this item

How do I install the 100 ft fiberglass compression packing seal, and what step is commonly missed?

Cut the required length from the 100 ft roll, wrap it around the shaft or valve stem with ends staggered, then compress evenly using the gland follower; the step often missed is staggering the joint ends to prevent a leak path.

What maintenance or replacement will the fiberglass packing need after extended service at high temperature?

The fiberglass material resists chemicals and handles up to 380 Degrees F, but gradual compression set and surface wear will eventually require the packing to be re-tightened or fully replaced to maintain a seal.

What is the first performance limit reached when the packing operates continuously near its 380 Degrees F maximum temperature?

Sustained exposure near 380 Degrees F accelerates fiber degradation and loss of tensile strength, causing the seal to lose conformability and leak before the temperature rating itself is exceeded.
