Garlock Blue Gard 3400 (Grey-Black Sheet)

Garlock BLUE-GARD 3400 Aramid fibers with an SBR binder.

A compressed non-asbestos gasket sheet of aramid fibers and high-temperature fillers with an SBR binder.  Often used in low-pressure saturated steam applications.

The Garlock® BLUE-GARD® compressed, non-asbestos (CNA) gasketing line offers a variety of elastomers to excel in a wide range of services. Garlock® BLUE-GARD® compressed gasketing offers excellent sealablitiy. The unique blend of aramid fibers, fillers and elastomeric binders provides improved torque retention and drastically lowered emissions levels. BLUE-GARD® CNA Gasketing offers cost savings by cutting operational costs through reduced waste, maintenance, stocked inventory, fluid loss, and energy consumption.  



  • Excellent Sealability
  • Unique blend of aramid fibers, fillers and a SBR rubber binder provides improved torque retention and drastically lowered emissions levels
  • Cuts operational costs through reduced:- Waste- Waste- Maintenance- Stocked inventory- Fluid loss- Energy consumption


Compatible With:

  • Water
  • Saturated steam*
  • Inert gases


*These styles are not preferred choices for steam service, but are successful when adequately compressed. Minimum recommended assembly stress = 4,800psi. Preferred assembly stress = 6,000-10,000psi. Gasket thickness of 1/16" strongly preferred. Retorque the bolts/studs prior to pressurizing the assembly. For saturated steam above 150psig or superheated steam, consult Garlock Engineering
