These rectangular tubes are flame retardant, machinable, and electrically insulating. They’re made of epoxy resin, making them good for use with printed circuit boards, insulating washers, and transformer components. With low moisture absorption, these tubes are often used as thermal insulators. Made with fiberglass fabric reinforcement, they’re strong and easier to machine than other glass cloth phenolics. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.

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

Color: Yellow
Max. Temperature: 355° F
Tensile Strength: 35,000 psi (Excellent)
Impact Strength: 10 ft.-lbs./in. (Excellent)
Hardness: Rockwell M115 (Extra Hard)
For Use Outdoors: No

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. They keep at least 50% of their structural strength at temperatures above 300° F. The tubes are made of a flame-retardant epoxy resin that is reinforced with fiberglass fabric.

Garolite G-11/FR5 is also known as epoxy fiberglass, epoxy-grade industrial laminate, and phenolic.

Temperature Range: -450° to 280° F
Tensile Strength: 40,000 psi (Excellent)
Impact Strength: 7.5-9.5 ft.-lbs./in. (Excellent)
Hardness: Rockwell M110 (Extra Hard)
For Use Outdoors: Yes
Specifications Met: MIL-I-24768/2

Rated for temperatures down to -450° F, this Garolite G-10 CR performs better in cryogenic applications than other glass epoxies. An excellent thermal insulator, it’s often used to transport liquid gases. It also prevents the flow of electrical current. This Garolite keeps its shape without cracking when bent. It has a glass fabric base for strength.

Arc-Resistant GPO3 Fiberglass Square Tubes

Color: Red
Temperature Range: -50° F to 265° F
Tensile Strength: 10,000-15,000 psi (Good)
Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
Hardness: Barcol 50 (Hard)
For Use Outdoors: No
Specifications Met: UL 94 V-0

Route and insulate wire using these square fiberglass tubes, which fit better along edges and around corners than round tubes. Use them for electrical applications in humid locations. They’re arc and track resistant, and better electrical insulators than FRP fiberglass. Made of fiberglass-reinforced polyester, they’re also known as polyester-grade industrial laminate.
