Sapphire Scientific Clear View Upholstery Pro Clear Housing

Replacement clear housing, complete with glide, for the Sapphire Scientific Clear-View Upholstery Pro (AW59). Sapphire part number , also catalogued as Legend Brands 106991.
This is the complete cover assembly, not the cover alone — the glide is supplied with it.

Why the housing matters:

On an upholstery tool the clear cover does two jobs. It lets the operator see the fabric and the recovered water as it comes off, which is how you judge when a section is clean and when it is dry enough to stop. And with the glide it forms the sealing face against the fabric.

A cracked, crazed or clouded housing costs you both. You lose the view, and once a crack opens up you lose vacuum through it — which shows up as fabric staying wetter than it should, the exact fault an upholstery tool exists to avoid.

When to replace it:

Cracked or chipped — replace it. A crack in the cover is a vacuum leak.
Clouded or crazed so the fabric is no longer clearly visible.
Glide face worn, scratched or plugged, since the glide comes with this assembly.
Sealing edge distorted after a drop or a knock.
