About Composites

Fiberglass Pipe for Corrosive Chemicals

With excellent corrosion resistance, this pipe can handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. Layers of fiberglass give this pipe better strength and durability than any of our other pipe for chemicals.

Garolite

Economical Electrical-Insulating Garolite XX Tubes

Stronger than Garolite CE with better electrical-insulating properties, Garolite XX is often fabricated into low-cost electrical components.

Halogen-Free Garolite G-10 Tubes

Use Garolite G-10 in place of Garolite G-10/FR4 for applications that are sensitive to halogen, such as in nuclear plants. It's strong, machinable, and electrically insulating.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Tubes

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Rectangular Tubes

These rectangular tubes are flame retardant, machinable, and electrically insulating.

Easy-to-Machine Garolite LE Tubes

Using nothing more than standard high-speed steel tooling, Garolite LE can be machined into intricate parts.

Economical Garolite CE Tubes

Garolite CE is often fabricated into parts where high strength is not required.

Flame-Retardant High-Temperature
Garolite G-11/FR5 Tubes

A flame-retardant version of Garolite G-11, these tubes are commonly used to make bushings, standoffs, and spacers for areas with high temperatures. All are stronger and resist heat better than Garolite G-10/FR4.

Electrical-Insulating Garolite XXX

More electrically insulating than Garolite XX, these tubes are often machined into insulating washers, bushings, transformer spacers, and parts of terminal boards.

Ultra-Low-Temperature Garolite G-10 CR Tubes

Rated for temperatures down to -450° F, this Garolite G-10 CR performs better in cryogenic applications than other glass epoxies.

Ultra-High-Temperature
Impact-Resistant Garolite Tubes

Used in turbine bearings, downpipe gaskets, and other machinery, these Garolite tubes withstand heavy impacts and temperatures as high as 500° F.

Fiberglass

Structural FRP Fiberglass Round Tubes

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Structural FRP Fiberglass Square Tubes

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Arc-Resistant GPO3 Fiberglass Round Tubes

Use these round GPO3 fiberglass tubes for electrical applications in humid environments.

Arc-Resistant GPO3 Fiberglass Square Tubes

Route and insulate wire using these square fiberglass tubes, which fit better along edges and around corners than round tubes.
