Garlock BLUE-GARD® Style 3200 Gasket

Garlock BLUE-GARD®: Reliable, clean-cut gasket material for sealing, insulation, and industrial applications

Garlock BLUE-GARD® is a high-performance compressed fiber gasket sheet used across industrial, automotive, plumbing, and mechanical applications. Fabricators choose BLUE-GARD® when they need a thin, durable, chemically resistant gasket material that seals reliably under compression, holds up to fluids and oils, and cuts cleanly into precise shapes. At SendCutSend, we laser cut .031 inch BLUE-GARD® to ±.009 inch tolerance, allowing for complex gasket shapes, bolt patterns, narrow sealing rings, and custom-fit profiles used in a wide variety of sealing systems.

What are the key things to know about Garlock BLUE-GARD®?

• Compressed fiber sheet that seals reliably under compression
• Resistant to oils, solvents, water, and many common industrial fluids
• Stable under pressure and maintains shape when clamped
• Cuts cleanly into intricate gasket geometries
• Designed for mechanical, plumbing, and industrial sealing applications

Why do fabricators choose Garlock BLUE-GARD® for gaskets and sealing applications?

Garlock BLUE-GARD® is chosen because it delivers reliable sealing performance at a thickness that remains easy to cut and install. It is engineered to compress uniformly and maintain sealing pressure over time, which makes it a trusted option for gaskets used in pumps, valves, flanges, housings, and machinery.

Common reasons fabricators select BLUE-GARD® include:

• It provides consistent, reliable sealing across a broad range of fluids.
• It cuts into detailed gasket shapes without fraying.
• It performs well under bolt-load compression.
• It handles both water and oil-based environments.
• It maintains dimensional stability during installation. BLUE-GARD® is frequently chosen when rubber, cork, or felt gaskets are too soft, or when metal gaskets are unnecessary or too rigid.

What is Garlock BLUE-GARD® typically made from and why does that matter?

Fabricators often ask about BLUE-GARD® composition. Garlock BLUE-GARD® is a compressed non-asbestos fiber sheet that generally includes fibers, fillers, and elastomeric binders selected for sealing performance. This construction means it offers: 

• Good compressibility and rebound
• Consistent density with no large voids
• Controlled leakage performance under bolt load
• Better chemical resistance than natural rubber gaskets
• Good lifespan in both static and low-pressure dynamic seals Its material consistency is one of the reasons BLUE-GARD® is favored for precision-cut custom gaskets.

How well does Garlock BLUE-GARD® laser cut?

Thin gasket materials often raise questions about burning, shrinking, or fraying during cutting. BLUE-GARD® adapts very well to laser cutting due to its density and controlled composition.

What to expect from laser cutting BLUE-GARD®:

• Clean, smooth edges
• Accurate interior holes for bolt patterns and fastener arrays
• Minimal discoloration • Very tight geometry for complex gasket shapes
• No unraveling or fiber tearing at the edges
• Repeatable accuracy for gasket sets .031 inch thickness laser cuts especially well, making it ideal for precision gaskets that require narrow walls, sharp corners, detailed contours, or small diameter holes.

What are the advantages of using Garlock BLUE-GARD®?

Excellent sealing performance

BLUE-GARD® is engineered for dependable sealing, making it a reliable choice for pumps, valves, flanges, and mechanical assemblies.

Resistant to common industrial fluids

It handles a wide variety of liquids including:

• Oils
• Water and steam
• Solvents
• Coolants
• Air and inert gases This versatility allows it to be used across many industries without material switching.

Maintains shape and compression set

Uniform density means it compresses predictably and maintains its thickness under bolt load, which is important for consistent sealing.

Ideal for laser cutting

Thin gasket materials can be challenging, but BLUE-GARD® responds very well to laser cutting and produces clean, accurate geometry.

Suitable for complex gasket profiles

BLUE-GARD® handles narrow gasket walls, small bolt holes, thin rings, and multi-layer sealing designs without tearing.

What are the limitations or drawbacks of Garlock BLUE-GARD®?

Not a high-temperature gasket

BLUE-GARD® handles moderate heat but is not suitable for extreme temperatures. High-temperature applications typically require:

• Graphite gaskets
• PTFE gaskets
• Metal-reinforced gaskets

Not recommended for high-pressure steam systems

BLUE-GARD® has good water and steam resistance but is not meant for high temperature and high pressure steam in industrial systems.

Not an elastomeric gasket

It has some flexibility but not the stretch or rebound of silicone, neoprene, or EPDM. It functions best in static seals where the gasket is compressed and remains in place.

Moisture tolerance varies by environment

While resistant to water, it is not intended for long-term soaking or constant water immersion where rubber would be a better fit.

Only available in one thickness

.031 inch is versatile but not suited for designs needing thick compressible seals.

How should I design parts for Garlock BLUE-GARD®?

BLUE-GARD® is very forgiving, but following good gasket design principles will improve sealing performance and longevity.

Recommended best practices:

• Keep thin walls wider than .060 inch to avoid tearing.
• Maintain hole diameters at or above material thickness for stable bolt holes.
• Ensure bolt patterns allow uniform compression.
• Include smooth curves instead of sharp internal angles when possible.
• Avoid extremely tight press fits, since over-stressing edges can lead to premature wear.
• For large gaskets, consider adding relief features to reduce stress during installation.

Where is Garlock BLUE-GARD® most commonly used?

Because BLUE-GARD® is a reliable, general-purpose compressed gasket material, it is found across many industries and equipment types.

Typical applications include:

• Flange gaskets
• Pump and valve seals
• HVAC system gaskets
• Compressor and vacuum sealing
• Oil and fluid system sealing
• Plumbing equipment
• Machinery access panels
• Chemical processing equipment
• Low pressure engine and mechanical assemblies Any time a thin, reliable, laser-cut gasket is needed, BLUE-GARD® is a suitable and frequently recommended option.

When should I use Garlock BLUE-GARD® for my project?

Choose Garlock BLUE-GARD® when you need a thin, durable, chemically resistant gasket material that seals reliably under compression and is easy to install.

BLUE-GARD® is the right choice if your gasket must:

• Provide consistent sealing pressure
• Cut cleanly into detailed profiles
• Resist oils, coolants, solvents, and water
• Remain dimensionally stable when clamped
• Perform in pumps, valves, HVAC equipment, or mechanical assemblies
• Require precise bolt-hole geometry
• Fit within low clearance or narrow sealing surfaces

It is not the best choice for:

• Extreme heat
• High pressure steam systems
• Situations requiring rubber-like elasticity
• Thick, spongy, or highly compliant gasket needs SendCutSend laser cuts .031 inch Garlock BLUE-GARD® to ±.009 inch tolerance with 2 to 4 day lead times, giving fabricators and engineers high quality gasket components ready for immediate installation.
