Raw Materials

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.

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.

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.

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.

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.

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.

Abrasion-Resistant Polyurethane Rubber Tubes

Use these tubes as jackets, seals, and insulation in areas where rubbing and scraping could cause wear on rubber. They are made of polyurethane, which combines the shock-absorbing qualities of rubber with the tear resistance of plastic.

Grommets

Split Grommets

A slit in the side of these grommets allows you to install them around wire, cable, and cords that are already in place. They snap into the hole and their wings hold them tight. Use them to turn rough-edged and uneven holes into smooth, insulated holes.

Locking Grommets

These grommets snap into place and have wings that expand against the sides of the hole to lock them in position. Use them to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth holes.

Expandable Locking Grommets

The center hole has flaps that flex to hold and protect various sizes of wire, cable, and cords while keeping out dust and debris. Snap these grommets into place and their wings expand against the sides of the hole to lock them in position. Use them to turn rough-edged and uneven holes into smooth holes.

Shrink-to-Fit Sealing Grommets

Apply heat and these grommets shrink around wire, cable, and cords to keep out dust, debris, and moisture.

Shaft Grommets

Support shafts, bearings, and other moving parts that are routed through a hole. These grommets are slippery to allow parts to move freely in the hole. Install them on thin sheet-metal panels.
