High Temp Silicone Threaded Plugs for E-Coating & Powder Coating

Description

Product Overview

When a standard push-in plug isn’t enough, professional finishers turn to Leader Masking Silicone Threaded Plugs.

Designed for critical masking applications, these plugs feature a fully threaded body that mimics the bolt. This ensures that the plug engages perfectly with the female thread, offering superior protection for the “lead thread” (the first turn) and preventing coating build-up.

They are the #1 choice for E-Coating (Electrocoating) and Sandblasting, where air pressure or liquid turbulence typically causes standard tapered plugs to pop out (“blow-out”).

Key Features & Benefits

• 🔒 Positive Mechanical Lock: Screws in securely. Guaranteed no blow-outs during high-pressure washing, shot blasting, or turbulent E-Coat dipping.

• 🔥 Extreme Heat Resistance: Made from premium silicone, resisting up to 315°C (600°F). Ideal for powder coating curing ovens.

• ⚡ Sealing Performance: The flanged head (washer design) creates a tight seal around the hole entrance, masking the grounding area perfectly.

• 🔧 Thread Protection: Protects the integrity of the internal thread profile from sand, paint, and plating deposits.

• ♻️ Reusable: Silicone material sheds paint easily. Simply unscrew and reuse.

Technical Specifications

• Material: 100% Virgin Silicone Rubber

• Thread Type: Metric (M), Unified (UNC/UNF), BSP available

• Max Temp: 600°F (315°C)

• Chemical Resistance: Excellent (Acids, Alkalis)

How to Choose the Right Threaded Plug?

Selecting a threaded plug is simple: Match the Plug to the Hole.

• If your part has an M8 threaded hole, you need an M8 Silicone Threaded Plug.

• Do not force a metric plug into an imperial hole, as it may cause leakage or thread damage.

Industry Applications

• E-Coating: Prevents liquid from entering the hole under immersion pressure.

• Powder Coating: Protects threads during high-temp curing.

• Sandblasting: Resists impact and won’t fall out like tapered plugs.

• Wet Painting: Ensures grounding points remain clean (if flanged).
