Uncoated Fiberglass Braided Sleeves | Unvarnished Fiberglass Sleeving – Manufacturer in India
At Harnawa Insulations, we manufacture superior quality uncoated fiberglass braided sleeves in India. These sleeves are designed to provide effective insulation as well as mechanical protection to wires, cables, and hose pipes. Our sleeves are made from braided or woven fiberglass material which does not have any varnish or resin coating on it.
Thus, we can say that our products provide reliable thermal resistance and flexibility. Our Uncoated Fiberglass Braided Sleeves are ideal for household wirings, automotive harnesses, and other electrical applications.
What is Uncoated Fiberglass Braided Sleeving?
The term uncoated fiberglass braided sleeves refers to those fiberglass sleeves that are not coated with any kind of varnish or resin and are made up of braided or woven fiberglass yarns only. Uncoated fiberglass sleeves are also called unvarnished fiberglass sleeves as compared to varnished ones.
This uncoated construction provides:
- Electrical insulation that is durable and decreases the possibilities of electricity leakage and formation of electrical faults
- Mechanical strength due to the construction of the braid or weave made of fiberglass that protects the cables from physical damage such as friction and impact
- Thermal resistance that allows using the product where there is heat generation by the components around
- Flexibility that facilitates the installation despite the lack of coating
Key Features & Advantages
- Effective Electrical Insulation – Fiberglass weave provides reliable insulation of wires and cables, preventing any electrical malfunction
- Mechanical Protection – Cabling braiding prevents damage due to rubbing, friction, or impact
- Excellent Thermal Insulation – Can be used in applications where heat can be generated by the components during their operation
- High Flexibility – Installation is easy as the material is slipped over the wires or cables without difficulty and can be easily adjusted to various shapes of cables
- Moderate Chemical Resistance – Provides some level of protection against chemicals, but not fully resistant
- Able to Come in Various Sizes – Comes in various diameters to suit different wire and cable gauges
- Budget-Friendly – An easier and cheaper alternative to varnish-coated sleeving for applications requiring only basic insulation and protection
Applications of Uncoated Fiberglass Braided Sleeves
Uncoated Fiberglass Braided Sleeves are widely used wherever basic mechanical protection and electrical insulation are required, including:

Frequently Asked Questions
Q1: What is the difference between uncoated and varnished fiberglass braided sleeve?
The main difference is that uncoated fiberglass braided sleeve does not have insulating varnish layer. Varnished sleeve uses both braiding material and varnish coating to provide extra insulation and protection. The latter increases dielectric and mechanical properties of the sleeve.
Q2: Is uncoated fiberglass braided sleeve resistant to chemicals?
Uncoated fiberglass braided sleeve provides resistance to mild chemical environment, but not to heavy one. It is suitable for low chemical exposure conditions only.
Q3: How to install uncoated fiberglass braided sleeve?
Installation is easy – you should just put the sleeve on the wire/cable/hose. We produce braided sleeves in several diameters to cover any type of cable.
Q4: Which industries use uncoated fiberglass braided sleeve?
Uncoated fiberglass braided sleeve is widely used in electronics, automotive industry, machinery industry, household appliances and electrical equipment manufacturing.
Q5: Does Harnawa supply uncoated fiberglass braided sleeves throughout India?
Yes, we are the largest manufacturer and supplier of uncoated fiberglass braided sleeves in India and supply electronics, automotive and other industrial companies all over India from Mumbai and Bhiwandi plants.
