Silicone Rubber Pipe Plug — T-Type End Cap for Large-Diameter PVC, Steel & Aluminum Pipes, Ø85–200 mm

Large-diameter pipe ends and panel holes in industrial, construction, and plumbing applications need a plug that seals completely, withstands temperature extremes and chemical exposure, and stays in place without adhesive or tools. This silicone rubber pipe plug uses a T-type flanged profile that compresses into the pipe end and seats flush against the surface—creating a secure, airtight seal by compression alone.

Made from food-grade organic silicone rubber, the plug is rated from -40°C to +250°C and resists corrosion, acids, alkalis, UV, aging, and static. Available in white or black, in 24 diameter sizes from 85 mm to 200 mm (in 5 mm increments), with quantity options of 1 to 5 pieces per order. The T-type flange prevents the plug from being pushed fully into the pipe during handling and provides a clean, finished appearance on the pipe face.

Use it to blank open PVC pipe ends, steel pipe ports, aluminum panel holes, sewer pipe openings, and equipment ports during storage, transport, installation, or spray masking—or as a test tube stopper in laboratory and food processing applications.

✅ Fits pipe ends and round holes from Ø85 mm to Ø200 mm — T-type flanged profile — white or black — compatible with PVC, steel, aluminum, and other round pipe and hole profiles

✅ Key Features of This Silicone Rubber Pipe Plug

  • 🧲 Food-Grade Organic Silicone Rubber: Environmentally friendly, food-safe silicone—suitable for food processing, laboratory, and medical equipment applications as well as standard industrial and construction use.
  • 🌡️ Wide Temperature Range −40°C to +250°C: Handles extreme cold and high heat—suitable for industrial pipe masking during powder coating, high-temperature spray finishing, and outdoor installations subject to temperature cycling.
  • 🔵 T-Type Flanged Profile: The flanged outer face seats flush against the pipe end or panel surface while the plug body compresses inside the opening—provides a secure, airtight seal that resists being pushed in or pulled out under normal conditions.
  • 🎨 White & Black Color Options: White suits food processing, laboratory, and clean-room environments; black suits industrial, automotive, and general-purpose applications. Select the color that matches your application or aesthetic requirement.
  • 📐 24 Diameter Sizes (Ø85–200 mm): Covers large-diameter pipe and hole sizes in 5 mm increments—select the diameter that matches your pipe inner dimension from the variant dropdown.
  • 📦 Quantity Options (1–5 Pieces): Order single pieces for one-off repairs or multi-packs for installation projects requiring multiple plugs of the same size and color.

🎯 Who Is This For?

🏭 Industrial Pipe & Equipment Port Blanking

Seal open ports on steel pipes, valves, pumps, and industrial equipment during storage or transport—the high-temperature silicone handles masking during powder coating and spray finishing without degrading.

🏗️ Construction & Plumbing Pipe End Sealing

Blank open PVC pipe ends, sewer pipe openings, and aluminum panel holes on construction sites—keeps debris, insects, and moisture out of pipe runs during installation and before final connections are made.

🧪 Laboratory & Food Processing Applications

The food-grade silicone construction and white color option make these plugs suitable for test tube stoppers and equipment port seals in laboratory and food processing environments where material safety and cleanliness are required.

❓ Frequently Asked Questions

How do I select the right diameter for my pipe?

Measure the inner diameter of your pipe end (the opening you need to plug). Select the plug diameter that matches or is very slightly larger than your pipe inner diameter—the silicone compresses to fill the opening and the flange seats against the pipe face. If your pipe inner diameter falls between two sizes, size up for a tighter compression fit.

Which color should I choose—white or black?

White is the standard color for food processing, laboratory, and clean-room environments where light-colored materials are preferred for hygiene and inspection purposes. Black suits industrial, automotive, and general-purpose applications where color is not a functional requirement. Both colors are made from the same food-grade silicone rubber with identical performance specifications.

Is this plug suitable for high-temperature spray masking during powder coating?

Yes. The silicone is rated to +250°C, which covers the oven temperatures used in most powder coating processes (typically 160–200°C). Press the plug into the pipe end before coating and remove after curing. The T-type flange prevents the plug from being pushed fully into the pipe during handling.

Can this plug be used on PVC sewer pipes?

Yes. The silicone rubber is chemically resistant to the contents of standard sewer and drainage pipes. It is suitable for temporarily blanking sewer pipe openings during construction or repair work. For permanent or pressure-rated applications, verify the plug’s pressure rating against your system requirements.

How do I install and remove the plug?

Press the plug body into the pipe opening by hand until the flange seats flush against the pipe face. The silicone compresses to grip the pipe wall. To remove, grip the flange and pull firmly—the plug releases cleanly without tools. The silicone retains its shape after removal and can be reused.

Is the silicone food-grade and safe for laboratory use?

Yes. The plug is made from food-grade organic silicone rubber—environmentally friendly and safe for contact with food and laboratory materials. It is suitable for use as a test tube stopper or equipment port seal in food processing and laboratory environments.
