Purpose and Fit

The HOFFMAN AS075SS conduit hole seal closes unused pushbutton or conduit openings in electrical enclosures. It fits a 1.06 in diameter hole and matches .75 in conduit size for a precise mechanical match. Installers and maintenance teams use it to maintain enclosure integrity when a knockout is no longer needed.

Material and Environmental Performance

The seal is formed from 304 stainless steel, providing corrosion resistance in damp or chemically exposed locations. The metal construction withstands temperature cycling without degrading and adds no measurable power draw or acoustic signature to the installation. It maintains a tight fit under normal vibration and thermal expansion.

Sustained Load Behaviour

Under continuous environmental stress the stainless steel retains its shape and sealing force without creep. The material resists oxidation and chemical attack over long service periods, keeping the enclosure rating intact. No maintenance or re-torquing is required once the seal is seated.

Questions about this item

How do I install the AS075SS hole seal in a 1.06 in opening and what step is often missed?

Align the 304 stainless steel seal over the 1.06 in hole and press firmly until the flange seats flat; the step often missed is verifying the 0.75 in conduit size matches the knockout before pressing.

What maintenance or replacement will the 304 stainless steel seal need over time?

The 304 stainless steel seal requires no scheduled maintenance; replace only if physical damage or corrosion appears around the 1.06 in opening.

What is the first limit that appears when the seal is exposed to sustained heat or vibration?

The 304 stainless steel material resists heat and vibration well; the first practical limit is mechanical loosening if the mounting surface deforms around the 1.06 in hole.
