Leader Masking EPDM Rubber Caps are the cost-effective alternative to silicone for applications where extreme heat (>200°C) is not required. Made from high-grade EPDM rubber, they offer superior resistance to harsh chemicals, making them the #1 choice for Plating, Anodizing, and Wet Painting.
-
Material: EPDM Rubber (Black)
-
Max Temp: 177°C (350°F)
-
Key Feature: Excellent Acid/Alkali Resistance
-
Cost: 20-30% cheaper than Silicone
-
Leader Masking Green Masking Discs (also known as Masking Dots) are pre-cut circles made from our premium Green PET Tape. Designed for speed and precision, they allow operators to mask grounding points and holes 50% faster than using standard tape rolls.
-
Material: Green Polyester (PET)
-
Adhesive: Silicone (No Residue)
-
Feature: Pre-cut on a clear liner for fast peeling
-
Max Temp: 204°C (400°F)
-
Leader Masking Green Polyester Tape (also known as Green PET Tape) is the industry standard for general-purpose high-temperature masking.
Combined with a durable PET carrier and a specially formulated Silicone Adhesive, our tape bonds firmly to difficult surfaces (like metal, plastic, and glass) but peels off in one piece after the baking cycle. It is the perfect partner for our Silicone Plugs and Caps.
-
Color: Green (Translucent)
-
Adhesive: Silicone (No Residue)
-
Max Temp: 204°C (400°F) Continuous
-
Feature: Strong backing, will not break upon removal
-
Leader Masking Polyimide Tape (often called Kapton Tape) is our highest-performance masking tape. Featuring a thin, amber-colored film and a premium Silicone Adhesive, it offers superior heat resistance up to 260°C (500°F) without shrinking or leaving residue.
-
Color: Amber (Golden)
-
Max Temp: 260°C (500°F) Continuous
-
Adhesive: Silicone (Clean Removal)
-
Feature: Ultra-thin for precision masking lines
-
Leader Masking Silicone End Caps are designed to mask external features such as threaded studs, pins, and tube ends. The flexible silicone stretches slightly over the part to create an air-tight seal, preventing paint, powder, or plating liquid from reaching the threads.
-
Material: High-Grade Virgin Silicone (600°F / 315°C)
-
Fit: Stretches for a tight grip (Won’t fall off)
-
Application: Studs, Pins, Shafts, Tube Ends
-
Feature: Reusable & Chemical Resistant
-
Leader Masking Silicone Pull Plugs are designed for masking through-holes and threaded bores. The long handle allows the operator to easily pull the plug through the hole, creating a tight seal on both ends.
-
Material: High-Grade Silicone (600°F / 315°C)
-
Design: Tapered body with a pull-tab handle
-
Application: Ideal for masking the leading thread chamfer
-
Efficiency: Faster insertion and removal than standard plugs
-
Leader Masking Tapered Plugs are the industry standard for masking holes during Powder Coating, E-Coating, Anodizing, and Plating.
Made from high-grade silicone, these plugs can withstand temperatures up to 600°F (315°C) without melting or hardening. The tapered design allows one plug to fit a range of hole sizes, ensuring a tight leak-proof seal.
-
Material: 100% High-Temp Silicone
-
Temp Resistance: 315°C / 600°F
-
Color: Color-coded by size (Custom colors available)
-
Application: Threaded and non-threaded holes
-
Leader Masking Silicone T-Plugs feature a solid body with a wide flange (washer) on top. This dual-action design masks the hole while simultaneously creating a circular clean area around the opening for electrical grounding (earthing).
-
Design: T-Shape with Integrated Flange
-
Function: Masks hole + Creates grounding ring
-
Temp: Up to 315°C (600°F)
-
Feature: Cannot be pushed all the way through
-
Leader Masking Silicone Threaded Plugs are designed to screw directly into threaded holes, providing a positive mechanical lock. Unlike tapered plugs, they will not pop out under pressure during E-Coating, liquid painting, or sandblasting.
-
Material: High-Grade Silicone (600°F / 315°C)
-
Design: Flanged head for easy installation & removal
-
Feature: Positive sealing for threaded holes (Metric, BSP, UNF)
-
Best For: E-Coating tanks & pressurized washing
