Introducing APM Hexseal's line of reusable, vibration-resistant, self-sealing fasteners. These patented pre-assembled self-sealing fasteners are 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 fastened 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-resistance and reusable, SEELSCREWS®, SEELBOLTS®, SEELRIVETS®, and SEELNUTS® can withstand internal/external pressures up to 6,000psi at temperatures from -160ºF to +500ºF.
Made in the USA, APM Hexseal self-healing 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.
HPM Hexseal's self-sealing fasteners offer a superior sealing alternative to compounds, tape, chemical coatings, and deformable washers that attempt to seal the threadform.
An application summary includes the following:
Also available from APM Hexseal are Switch Seals, Circuit Breaker Boots, and a range of custom application seal options.
