Our High Temperature Masking Plugs are engineered to deliver outstanding performance in harsh, high-heat environments. Designed to seal and protect both threaded and non-threaded holes, these masking plugs are ideal for use in finishing processes such as powder coating, anodizing, e-coating, and high-temp painting—withstanding continuous exposure up to 316°C (600°F).
Designed to improve efficiency and reliability, our masking caps offer the following key benefits:
Durable high-temp resistance: Withstand extreme temperatures without cracking, shrinking, or egrading.
Versatile fit: Available in multiple shapes and sizes to suit a wide range of hole diameters and thread types.
Simple application: Easy to install and remove—no special tools required.
Choose from various materials including:
Silicone: Excellent heat resistance, flexibility, and reusability.
EPDM: Resistant to heat, chemicals, and weathering.
TPE: Combines flexibility with heat resistance and chemical durability.
PVC: Cost-effective for medium-temp processes with good sealing capability.
Our masking caps are trusted across a variety of industries for their reliable performance in demanding environments. In the automotive sector, they effectively shield engine blocks, manifolds, and other components during coating processes. In electronics, they are used to mask connectors and ports during soldering or the application of conformal coatings. For general manufacturing, these caps are ideal for batch processing and repetitive high-temperature tasks, ensuring consistent protection and efficiency.
First Thread Protection Plugs are used to provide masking to the first thread of standard female threads. They feature an ergonomic pull-tab that allows for simple installation and removal.
Suitable for a range of masking applications that include; powder coating. e-coating, plating and anodizing.
The range is available in different material options. Silicone is a premium masking material due to its high temperature rating. EPDM is an economical material with lower heat resistance, but superior chemical resistance. Both material options can be used multiple times.
Materials: Silicone 600F (316C) and EPDM 425F (218C)Colors: Natural and BlackHardness: Durometer (Shore A) 50+5
Our range of High Temperature Masking Plugs are available as a solid plug or with a hollow core. These reusable tapered plugs are available as either a premium Silicone Plug or as a cost-effective EPDM plug.
The Hollow Tapered Plugs provide an economical solution for large diameter holes. The hollow center aids compression for improved sealing.
Silicone Tapered Plugs are a premium option due to the high temperature rating of 600F (316C). High Temp Silicone Plugs can be used multiple times. Hardness; Durometer (Shore A) 55+5. Various colour options are available, including; Natural, Blue, Green, Grey, Pink, Purple, Red and Yellow.
The Black EPDM tapered plug is an economical material has a slightly reduced heat resistance with a high temperature rating of 435F (218C), but boasts superior chemical resistance.
Masking Cone Plugs are a versatile masking solution that can be used as a plug or as a cap. The tapered design allows the part to plug a range of inside diameter sizes and to cap a range of outside diameter sizes. These plugs are ideal for a range of masking applications, including; powder coating, e-coating, plating and anodizing.
The range is available in a choice of materials that include premium Silicone and economical EPDM. Silicone benefits from a high temperature rating and can be used multiple times. EPDM is also reusable with a lower heat resistance, but superior chemical resistance.
Masking Flangeless plugs are designed to mask holes without masking the surrounding surface area. The tapered design allows mulitple hole diameters to be protected. Ergonomically friendly profile has a pull-tab for easy installation and removal. These come in a premium high-temp silicone material or in a economical reduced temp EPDM material. Applications include Powder Coating, E-Coating, Plating and Anodizing.
Masking Pull plugs are ideal for masking threaded and plain through-holes. To apply, just pull the thinner end of the plug through the hole until it stretches the larger end through the hole; then release it so it will compress and make a tight seal. Use the Flanged Pull plugs to mask the backside of the hole. These come in a premium high-temp silicone material or in an economical reduced temp EPDM material. Applications include Powder Coating, E-Coating, Plating and Anodizing.
Multi-Flanged Plugs are designed to mask plain or threaded holes. Part will mask off the hole while allowing paint up to the hole. Will fit a range of holes due to the flexible multi sized flange design.
Paper Masking plugs are made from a blend of post consumer and virgin paper that can be recycled. They are an economical solution to mask holes and paper will not promote condensation. Can be used in painting or lower temperature powder coating applications.
Parallel protection plugs are general-purpose plugs that are used to protect a variety of applications. It has a parallel design that ensures a secure and snug fit while preventing contaminants, damage, dirt, corrosion, moisture, and debris during storage and transportation. It is highly fragmentation-resistant and suited for threaded applications.
The plug has a closed top design and convex sides to ensure a secure fit. It is easy to install and remove and provides a neat finish. Suitable for various applications in different industries, including automotive, manufacturing, and commercial.
