Sealed Self-Clinching Standoffs with Integrated Flange Sealing Layer

Sealed self-clinching standoff in the sealing range, where leak tightness is the acceptance criterion rather than push-out alone.

Product overviewOverview

Reliability depends on the flatness of the panel face and on press force. Water enters an enclosure along the annular gap between standoff and panel, so the seal has to close that gap continuously. Leak testing at the specified pressure is the only reliable check, because a seal can look complete and still pass water at a joint that is not fully compressed.

Material: Stainless Steel / Brass. It is pressed into a prepared hole from one side.

Key featuresFeatures

Leak test at the specified pressure rather than inspect visually.
Seal material and compression selected to the required IP rating.
6H thread keeps the joint serviceable.
Stainless or nickel-plated steel for outdoor and wet service.

Typical applicationsApplications

EV power electronics housings
Chargers and energy storage cabinets
Floor scrubbers and cleaning equipment

Selection notesSelection

For higher medium pressure, add thread sealant as well; the flange seal alone is not designed for high pressure.

Frequently asked questionsFAQ

How is a sealed standoff verified?

By a leak or pressure test on the assembled panel. Visual inspection cannot show whether the seal is continuously compressed around the full circumference.

What matters during installation of the Sealed Self-Clinching Standoffs (Waterproof Series)?

Press it into a prepared hole from one side. Leak test at the specified pressure rather than inspect visually.

Manufacturing and inspection

Seal compression checked on cross-sections against the design window.Alternative materials and finishes can be quoted side by side during sampling, so cost and corrosion resistance can be traded off explicitly.
