Zoro Select

Zoro Select ZUSA-RES-50 Compression Packing Seal 100 ft

SKU CH-0ZZ1-NAC5Z

Fibreglass compression packing seal, 100 ft long, withstands 380 °F and resists chemicals

  • Withstands extreme heat up to 1,380 °F
  • Chemical-resistant fiberglass resists corrosive fluids and gases
  • Flexible round edge conforms to uneven sealing surfaces
  • High tensile strength of 3,200 N/mm ensures durability
  • 100 ft roll provides ample length for large jobs

Compression Packing Seal 100 ft

This compression packing seal provides 100 ft of continuous fiberglass material for industrial sealing tasks. It targets maintenance teams and plant engineers who need a flexible, chemical-resistant barrier that conforms to uneven surfaces across pumps, valves and flanges.

Thermals noise and power draw

The seal withstands a maximum temperature of 380 Degrees F and has no minimum temperature limit, so it remains stable in high-heat process lines. Its dense 75 lb/cu ft fiberglass construction resists thermal cycling without degrading, and the inert material adds no electrical load or acoustic signature to the installation.

Build fit and system impact

Supplied as a 1200 in length with a 1 1/2 in thickness and round edge profile, the white fiberglass rope fits standard stuffing boxes and can be cut to exact gland depths. The 3 200 N/mm tensile strength lets it hold compression under vibration, freeing technicians from frequent re-torquing while the chemical-resistant fibers protect adjacent metal components from corrosive media.

Questions about this item

How do I install the 1 1/2 in thick fiberglass seal and what step do people usually miss?

Cut the 100 ft roll to length, wrap it around the shaft or valve stem with the round edges meeting, then compress it evenly using the gland follower; the step most often missed is staggering the joints so no two ends line up, which prevents leak paths.

What maintenance or replacement will the fiberglass packing need later?

Plan to re-torque the gland nuts after the first few heat cycles to 380 °F, then inspect annually; replace the packing when compression no longer seals or the material hardens, typically after several thousand hours of service.

What limit appears first when the seal runs continuously at high temperature?

The 380 °F maximum temperature is the first hard limit; sustained operation above it degrades the fiberglass and chemical-resistant coating, causing loss of the 3 200 N/mm tensile strength and eventual leakage.
