Hex Flange Seal Bolts

If your equipment is exposed to high pressure, contamination, or vibration, then protect it with ZAGO’s hex flange sealing nuts. Our hex flange sealing nuts are unique because they are designed with an ingrained rubber element. The power of our sealing technology is unleashed when the nuts are torqued, causing the rubber element within them to form a vacuum-tight seal along the threading of the bolt.
