CATALOG SF300A SELF-SEALING FASTENERS SELF- SEALING WASHERS WHEN JUST FASTENING ISNT ENOUGH

When just fastening isnt 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 compatibility with a wide range of gases and liquids. They represent a superior sealing alternative to sealing compounds, tape, chemical coatings, and deformable washers that

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.)

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.
