White Silicone T-Type Hole Plug — Blanking Bung & End Cap, 6.8mm–25mm, 25 Sizes

Unused or exposed holes in furniture, panels, pipes, and enclosures collect dust, allow moisture ingress, and leave an unfinished appearance. This T-type silicone hole plug provides a clean, secure, waterproof blanking solution for round holes from 6.8mm to 25mm in diameter — pressing in from one side and locking in place via the flanged cap without adhesive, fasteners, or tools.

Made from food-safe silicone rubber (Shore hardness 50), rated from -40°C to +250°C, and resistant to UV, acids, alkalis, aging, and corrosion. Available in 25 sizes from A=6.8mm to A=25mm (where A is the small-end insertion diameter). Prices from $2.34 per plug. White color — suited for white furniture, white panels, and light-colored surfaces where a discreet, color-matched finish is required.

Suited for furniture leg holes, cabinet and panel blanking, washbasin and sink drain plugging, security door screw holes, automotive body panels, powder coating and painting masking, and pipe end sealing.

✅Sizing note: The size listed (A) is the small-end insertion diameter — the tapered stem that inserts into the hole. For a secure, non-falling seal, select a size one step larger than your measured hole diameter. Example: for a 10mm hole, select A=11mm or A=12mm for best retention and sealing.

✅ Key Features of This White Silicone Hole Plug

🔘T-Type Snap-On Design: The T-shaped profile — a flanged cap with a tapered insertion stem — presses into the hole from one side and locks in place via the flange lip. No adhesive, no tools, no fasteners required. Removable and repositionable.
🧲Premium Silicone Rubber: Non-toxic, food-safe silicone (Shore 50) is soft and flexible — conforms to hole edges for a tight seal without cracking, shrinking, hardening, or breaking over time. Safe for use in food-contact adjacent applications.
🌡️Wide Temperature Range: Rated -40°C to +250°C — maintains flexibility and sealing performance in freezing outdoor conditions and high-temperature industrial, automotive, or powder coating oven environments.
💧Waterproof, Dustproof & Odor-Proof: The flanged T-profile creates a waterproof, dustproof, and odor-proof barrier when correctly sized — suitable for washbasins, kitchen sinks, bath tubs, outdoor equipment, and IP-rated enclosure blanking.
📏25 Sizes from 6.8mm to 25mm: Covers a wide range of common hole sizes in furniture, panels, and pipes — from 6.8mm up to 25mm in increments as small as 0.5mm. Order the exact size for your application.
🎨Clean White Finish: White color provides a discreet, color-matched finish on white furniture, white panels, and light-colored surfaces — a cleaner result than black plugs on light backgrounds. Also available in black and other colors.

🎯 Who Is This For?

🪑Furniture & Cabinet Hole Blanking

Cover unused holes in table legs, chair legs, cabinet panels, bed frames, and brackets — the white finish blends cleanly with white and light-colored furniture for a professional, finished appearance.

🚿Washbasins, Sinks & Bath Tubs

Plug unused drain holes, overflow holes, or fitting holes in washbasins, kitchen sinks, bath tubs, and foot tubs — waterproof and odor-proof seal prevents water and drain odors from passing through unused openings.

🚗Automotive & Spray Painting Masking

Use as spray masking plugs during powder coating, painting, anodizing, plating, and media blasting to protect threaded holes and bores from surface treatment ingress — silicone withstands oven curing temperatures up to 250°C.

⚡Panels, Enclosures & Security Doors

Blank unused holes in security door screw positions, electrical panels, junction boxes, and outdoor equipment enclosures — dustproof and weatherproof seal maintains a clean, finished appearance.

❓ Frequently Asked Questions

How do I select the correct size?

The size (A) refers to the small-end insertion diameter — the tapered stem that inserts into the hole. Measure your hole diameter accurately using calipers or a ruler. Then select a plug size one step larger than your measured hole for a secure, non-falling fit. For example: if your hole measures 10mm, select A=11mm or A=12mm. Selecting the exact hole size may result in a loose fit that does not seal reliably.

Is this plug waterproof and suitable for sinks and washbasins?

Yes — when correctly sized (one step larger than the hole), the T-type flange and tapered stem create a waterproof and odor-proof seal. It is suitable for plugging unused holes in washbasins, kitchen sinks, bath tubs, and foot tubs. Ensure the plug is fully seated with the flange flush against the surface for the best seal.

Can this plug be used for powder coating and spray painting masking?

Yes — the silicone material is rated to +250°C, making it suitable for use as a masking plug during powder coating, painting, anodizing, plating, and media blasting processes. Insert the plug before the surface treatment process and remove after completion.

Can the plug be removed and reused?

Yes — the snap-on design is removable. Pull the plug out from the flange side. Silicone retains its flexibility and shape after removal, so the plug can typically be reused multiple times provided it has not been damaged or permanently deformed.

Is this plug available in other colors or larger sizes?

Yes — this plug is also available in black and other colors. Sizes up to 201.5mm are available in the full product range. If you need a size larger than 25mm or a bulk quantity, please contact our customer service team with your size and quantity requirements.

Is the silicone material safe for food-contact adjacent applications?

Yes — the silicone rubber used is non-toxic and food-safe, making it suitable for use in kitchen environments including sink and washbasin hole plugging. It does not leach harmful substances and is resistant to common household cleaning agents.
