STS Series - Silicone Tapered Stoppers
- Tapered Design to Fit a Variety of Hole Diameters
- Compressible for Better Sealing of Both Threaded and Non-Threaded Holes
Product Description:
Our Silicone Tapered Stopper (STS) product line is an industry standard for general plugging applications. With many sizes available, holes from 0.020" to 4.710" in diameter can easly be plugged. Our high temperature silicone is specially formulated to ensure reusability and reliability during masking.
Typical Applications:
- Used as a plug in both threaded and non-threaded holes and in combination with hardware to seal off large cavities.
Helpful Hints:
- Make sure that the major diameter of the plug is at least 15% larger than the hole diameter.
- The minor diameter should be at least 15% smaller than the hole diameter.
- When masking off both the front and back of a cavity, it is possible to combine two (STS) with hardware to create a liquid tight mask that resists blow-out. Call for details.
- Silicone Tapered Stoppers are not recommended for exposure to aggressive chemicals or hydrocarbons.
