Frequently Asked Questions

Frequently Asked Questions

What is silicone fiberglass sleeving used for?

Silicone fiberglass sleeving is commonly used to protect and insulate motor leads, transformer leads, appliance wiring and industrial electrical routes where heat, abrasion and flexibility must be considered together.

When should I choose silicone fiberglass sleeving instead of heat shrink tubing?

Choose silicone fiberglass sleeving when the part needs flexible routed insulation without heat recovery. Choose heat shrink tubing when the design needs a tight recovered cover, marking, sealing or terminal strain relief.

What details should I send before requesting samples?

Send the protected part, inner diameter, wall requirement, temperature, voltage, routing movement, color, length and any customer validation or document requirements.
