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. Fullyadjustable 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. (OTHER SEALING MATERIALS AVAILABLE. SEE TABLE I, PAGE 4.)

O-ring silicone rubber per ZZ-R-765 Class I II, Grade 70. Other sealing materials available. Temperature Range: -160 F to +500 F (-106 C to +260 C) Pressure Range: Up to 6000 psi, internal and external, subject to installation procedures. Shelf Life: Excess of 25 years. Resistant to: Salt water, weather, dirt, dust, sunlight, ozone and most acids. See Table I. Installation: Install in same manner as standard rivets. Standard break-edge practices for deburring (i.e. break sharp edges 0.005" maximum) are permissible. HOW TO ORDER When ordering SEELRIVETS , specify head style, rivet diameter and length. Example: To order a Type SRU with a 5/32" diameter, 3/4" long, specify: SEELRIVET SRU 5/32 x 3/4" SEELRIVETS are designed to seal out air, water, lubricants, and other liquid or gaseous contaminants. Installed like an ordinary rivet, SEELRIVETS form a high-pressure seal while permitting metal-to-metal contact. Stock SEELRIVETS are universal head furnished in aluminum alloy for aircraft applications. These Type SRU SEELRIVETS have the exact dimensions of AN470 and MS20470 rivets. Type SRC, 100 countersunk, flathead versions are also available as non-stock items. Other rivet types/materials and O-ring seal formulations are also available on special order.
