SCREWS BOLTS

Poco Sales is a stocking distributor for APM HEXSEAL's line of self sealing fasteners.

When fastening is required in a high-pressure/vacuum or leakage-sensitive application, the penetration of seamless surfaces by a screw, bolt or rivet creates a problem. There is now a hole which, even when filled by a conventional fastener, may leak.

APM Hexseal's 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 fastener head. This combination of precise groove geometry and O-ring characteristics results in an absolute high-pressure/vacuum seal regardless of surface finish, while still permitting full metal-to-metal contact. Vibration-resistant and re-usable, SEELSKREWS°, SEELBOLTS°, and SEELNUTS° can withstand internal/external pressures up to 6,000 psi at temperatures from -160°F to +500°F

Made in the U.S.A., APM Hexseal self-sealing fasteners are available in all standard thread sizes, including metric. 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 attempt to seal the threadform.
