Norton 636425-43112 Psa Back-up Pad 8 in Medium Tapered

Product Description

The NORTON 636425-43112 is a PSA (pressure-sensitive adhesive) back-up pad designed for use with 8-inch disc abrasives on dual-action and random orbital sanders. Type X construction provides a medium tapered profile, which helps support the abrasive disc evenly across the pad face and reduces edge loading during sanding passes. Rated for 60 grit disc applications, this pad is sold individually and is suited for finishing work in woodworking, auto body, and general surface preparation trades where consistent disc contact and reliable adhesive hold are required.

This back-up pad is intended for professional use with dual-action and random orbital sanders that accept 8-inch PSA abrasive discs. The medium tapered Type X design is commonly used in applications where a flexible, conforming pad is needed to follow slightly curved or flat surfaces. Typical install scenarios include auto body finishing shops, cabinet shops, and general fabrication environments where high-volume disc sanding is performed.

Compatibility

Designed for use with 8-inch PSA abrasive discs on dual-action and random orbital sanders. No specific sander model compatibility was provided by the manufacturer for this listing.

Installation Notes

Attach the back-up pad to the sander spindle according to the sander manufacturer's torque and thread specifications before applying any abrasive disc. Power down and disconnect the sander from its power source before changing the pad or disc. Align the PSA disc carefully to the pad face before pressing into contact, as repositioning adhesive-backed discs can degrade the adhesive bond. Inspect the pad surface regularly for wear, glazing, or deformation that could cause uneven abrasive contact.
