G7 Glass Reinforced Silicone Tubes - .187 inch wall thickness 3/16

NEMA G-7 Tubes satisfies MIL-I-24768/17 GSG, IEC 60893-3 Type 6 SI GC 201

G7 Tubes are manufactured of Glass Cloth Reinforced Silicone.

 Composed of a continuous glass woven cloth base impregnated with a silicone resin binder, this grade has excellent heat and arc resistance. 

Silicone thermosetting resins are among the best of all polymer materials in resistance to temperature. 

Hence, silicone is broadly used for high temperature electronic applications requiring low electrical losses. 

Silicone isn't as strong as epoxies and phenolics upon aging at lower temperatures but is stronger upon aging over 400° F.

G7 has extremely good dielectric loss properties under dry conditions and good electrical properties under humid conditions, although the percentage of change is high.

Tubes are made in 36" to 48" Lengths +/- 1.0" Length

G7 Silicone Tubes are available in the following  Wall Thickness,  Select:
