SEELNUTS

®

High-pressure, self-sealing locking nuts

SEELNUTS® are designed for use on all types of adjusting screws, threaded studs, and machine bolts in applications where leakage may

occur due to extreme pressures. Installed like an ordinary nut, SEELNUTS® form a high-pressure seal along the thread section and contact

surface when torqued. Their single-piece design eliminates the need for gaskets, sealing compounds and surface preparations. Fully-

adjustable and reusable, they resist vibration, provide metal-to-metal contact, and seal under vacuum or high pressure. Available in all

standard thread sizes, the integral seal can be formulated for compatibility with most gases or liquids.
