Silicon Sleeve

High-Performance Silicone Sleeves – Flexible, Durable & Built to Fit

A silicon sleeve might look like a simple tube or cover—but it plays a big role in insulating, sealing, and protecting parts in machinery, medical devices, kitchen appliances, and more. Known for their flexibility and heat resistance, silicone sleeves are essential across industries that demand clean, durable, and long-lasting solutions.
At DeePee Rubber, we offer a wide range of customizable silicon sleeves in various sizes, types, and silicone rubber materials to suit your exact requirements.

What Is a Silicon Sleeve?

A silicon sleeve is a tubular or strip-shaped covering made from silicone rubber or sponge. It’s designed to protect components from heat, moisture, dust, chemicals, and electrical interference. These sleeves are used on pipes, cables, fittings, wires, and connectors.
Whether you need insulation in a lab, cleanroom, kitchen appliance, or industrial machine, a silicone sleeve offers lightweight protection that doesn’t wear out easily.

Types of Silicone Sleeves

At DeePee Rubber, we manufacture various types of silicone sleeves to suit different applications:
  • Silicone Rubber Sleeves – General-purpose sleeves with excellent heat resistance.
  • Silicone Sponge Sleeves – Lightweight, compressible, and ideal for sealing gaps.
  • Silicon Tubing – Medical-grade, transparent, and flexible options available.
  • Silicon Strips and Silicon Cords – For edge sealing, cushioning, and insulation.
  • Silicone Inflatable Gaskets – Custom designs for door and hatch seals.
  • Silicone Door Gaskets – Often used in ovens, cleanrooms, and pharmaceutical setups.
  • Silicone Sponge Beading, Sponge Strip, Sponge Cord – Soft sealing components for uneven surfaces.
All our sleeves are available in custom sizes, with varying hardness levels, wall thicknesses, and color options.

Key Benefits of Silicone Sleeves

  • High heat resistance – Withstands extreme temperatures without deforming.
  • Chemical resistance – Works well in harsh, reactive environments.
  • Non-toxic & food-safe – Many grades available for kitchen and pharma use.
  • Excellent flexibility – Easy to stretch, fit, or compress as needed.
  • Durable under stress – Withstands wear, UV rays, and constant use.
  • Electrical insulation – Suitable for covering wires and connectors.
These benefits make rubber sleeves and silicon rubber sleeves the go-to option when performance and reliability are non-negotiable.

Applications of Silicone Sleeves

Silicone sleeves are widely used in:
  • Medical equipment – Tubing, cable covers, and surgical device insulation.
  • Food & pharma industries – For hygienic transfer and sealing.
  • Electronics & electrical setups – For wire insulation and short-circuit prevention.
  • Automotive – Protecting hoses, wires, and connectors from heat and friction.
  • Ovens and kitchen appliances – As sealing strips and high-temperature gaskets.
  • HVAC systems – To seal ducts, pipes, and prevent heat leakage.
Wherever heat, hygiene, or flexibility are key, silicone sleeves do the job.

How to Choose the Right Silicone Sleeve?

Here are a few things to keep in mind:
  • Temperature range – Choose the right grade depending on heat exposure.
  • Thickness & size – Match with the pipe, wire, or part it’s covering.
  • Material type – Sponge for flexibility, solid silicon for durability.
  • Color coding – For visibility, compliance, or aesthetic alignment.
  • Environmental exposure –UV, water, chemical resistance, pressure.

FAQs

What is the Durability of Silicone?
Silicone is known for its long-lasting strength. It resists wear, weather, and deformation over time.
Most silicone sleeves can handle -60°C to 230°C. High-temp grades go up to 300°C.
Not at all. It’s highly elastic and flexible, especially under pressure or heat.
With proper use, they can last years without needing replacement.
To protect wires, seal equipment, insulate parts, and withstand heat or chemicals.
Mild soap and water work well. They’re also resistant to many cleaning agents.

Yes, especially against oils, solvents, and reactive fluids. PTFE-lined versions offer even higher protection.
