Product Description
Silicone Tapered Plugs - 25.4mm Length - 6.35mm Max Diameter - Red Silicone | Vital Parts - STP015R
Our Silicone Tapered Plugs offer a high-performance masking and sealing solution designed to excel in extreme temperature environments. These versatile plugs are ideal for industrial processes such as powder coating, shot blasting, anodising, and printing, where precise protection and heat resistance are essential. With a tapered design and high-grade silicone rubber, these plugs provide a snug fit across a wide range of hole diameters.
What are Silicone Tapered Plugs?
Silicone Tapered Plugs, also referred to as Silicone Tapered Bungs, are made from a durable, high-temperature silicone rubber that can withstand sustained exposure to temperatures up to 315°C. Their flexible, conical shape makes them highly adaptable, allowing a single plug to fit a variety of hole sizes. This makes them especially popular for both production masking and protective sealing during surface finishing processes. Their reusability also makes them a cost-effective choice for high-volume operations.
