& SELF- SEALING WASHERS & SELF- SEALING WASHERS WHEN JUST FASTENING ISN’T ENOUGH ™ ®/L58169 Recognized

isn’t enough. APM Hexseal invented and patented pre-assembled self-sealing fasteners designed to provide both fastening and sealing integrity in a single unit. Their design features a resilient O-ring held captive in a precision engineered groove under the fastener head. This combination of precise groove geometry and O-ring characteristics results in an absolute seal regardless of surface finish, while still providing full metal-to-metal contact. Vibration-resistant and re-usable, SEELSKREWS ® , SEELBOLTS ® , and SEELNUTS® can withstand internal/external pressures up to 6,000 psi/vacuum at temperatures from –160°F to +500°F . Made in the U.S.A., APM Hexseal self-sealing fasteners are available in standard and metric thread sizes. And the integral seal can be formulated for com- patibility with a wide range of gases and liquids. They represent a superior sealing alternative to sealing compounds, tape, chemical coatings, and deformable washers that attempt to seal the threadform. Features and Benefits

• Positive sealing under pressure or vacuum.
• Easy-to-install … pre-assembled unit installs like a conventional fastener.
• Metal-to-metal contact resists loosening due to vibration, and assures fastening integrity.
• Re-usable … repeated installation and removal does not affect sealing effectiveness.
• Compatible with all surface finishes.
• UL and CSA Recognized … tested and listed to UL Standard 50, Types 1-13, and CSA Standard C22.2 No. 40.
• Optional O-ring seal materials assure performance with wide variety of gases and liquids.
• Uniformity and high strength assure repeatable performance.
• No adhesives, coatings or tape required. Typical Applications Sealing Performance Under High Pressure Custom Self-Sealing Fasteners Self-sealing SEELSKREWS® , SEELBOLTS® , SEELRIVETS ® and SEELNUTS ® are available in other sizes, lengths, materials, head styles (including tamper- resistant) and finishes. These can be produced with an O-ring material (see Table I) best suited for your application. Also, other types of fastening hardware like standoffs can be modified to become self-sealing. Should you not find what you need in this catalog, please consult the factory. We would be pleased to work with you to satisfy your specific application requirements.

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

SEELOC® Vibration-resistant, self-sealing washers SEELOC ® Washers are self-sealing, vibration-resistant washers, each having a silicone rubber section, molded and bonded to a stainless steel formed washer. These washers are designed for use with regular screws or bolts for sealing panels and cases having large clearance holes or slots, and can also be used to seal openings of protrusions as shown below. Upon tightening, a seal is formed under the head of the screw or bolt as well as around the periphery of the washer face.
