Metric Hex Flange Sealing Nuts

Metric hex flange sealing nuts are designed to withstand extreme pressure, and to form a complete seal along the threading of your bolt. Where liquids, gas, and contamination are present, it is crucial to use hex flange sealing nuts rather than ordinary nuts to ensure optimal performance from your equipment. These nuts contain a silicone element that is bonded directly into the heavy hex flange sealing nut. This eliminats the need for you to use any messy liquid sealants. The rubber segment, when the nut is torqued, forms an unbeatable seal about the threading of your bolt that remains strong no matter the conditions it is exposed to.

These one piece heavy hex flange seal nut grants you 360 degrees of sealing power whether its submerged under the ocean, launched into space, used for aviation, used in pneumatic or hydraulic systems, or in virtually any other application.

All parts are made from 18-8 Stainless Steel.

O-Ring Materials Available: Silicone (-SSS), Fluorosilicone (-FSS), Buna (-BSS), and Viton (-VSS).
