APM self-sealing locking nuts

The APM SEELNUT® is the original self-sealing nut designed and patented by APM. Our self-sealing locking nuts 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, our self-sealing locking nuts 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, these self-sealing locking nuts resist vibration, provide metal-to-metal contact, and seal under vacuum or internal/external high pressure.

APM self-sealing locking nuts are available in all standard thread sizes, and the integral seal can be formulated for compatibility with most gases or liquids. They can also be supplied with self-locking pellets.

APM's patented, pre-assembled self-sealing nuts, screws, bolts and rivets provide both fastening and sealing integrity in a single unit. Unique design features a resilient silicone O-ring held captive in a precision engineered groove under the head. Vibration-resistant and reusable screws, bolts and nuts withstand internal and external pressures/vacuum to 20,000 psig (137,895kPa). When vibration is an issue, APM offers a full line of self-locking add-ons (pellets, strips, patches).
