Overview

The High Temp Masking Supply 235-piece silicone rubber plug set is engineered to perform under demanding temperatures while delivering dependable seals for a wide range of hole sizes. The plugs respond with a soft, tactile feel during setup and removal, then rebound to their shape, helping you work efficiently without fiddling with mismatched closures. Suitable for both threaded and unthreaded openings, this kit covers diameters from 1/32 inch up to 1 inch, making it a flexible companion for masking, coating, and finishing tasks across different projects.

Kit at a glance

• 235-piece silicone plug set designed to cover a wide spectrum of openings encountered across powder coating, painting, and ceramic coating workflows, from tiny ports to larger bores.
• Size distribution ensures practical coverage across small, medium, and large holes: 50 pieces each for the two smallest sizes (1/32 inch to 3/16 inch), 25 pieces each for three mid sizes (1/8 inch to 3/8 inch), and 10 pieces each for six large sizes (3/8 inch to 1 inch).
• Assorted tapered plugs are designed to create a gradual seal that accommodates slight variations in hole diameter, reducing the likelihood of overspray or masking gaps during a coating run.
