Recommended for masking holes when hole can be reached from both sides when powder coating. When pulled through holes, the larger diameter (A) stretches and diameter compresses until released providing a tight seal, even helping to plug the thread chamfers on threaded applications. The major diameter (A) of the pull plug should be at least 4-5% larger than the hole to be plugged. Temperature resistant up to 315 C / 600 F and durable for repeat use.
