3M 7100066530 Windo-weld Round Ribbon Sealer Kit

Product Description

The 3M 7100066530 Windo-Weld Round Ribbon Sealer is a pre-formed, compressible butyl sealer used to create a watertight, vibration-resistant bond between automotive glass and the pinchweld flange. Each kit includes one 1/4-inch diameter x 15-foot roll of sealer along with setting blocks, providing enough material to complete a full windshield or backlite replacement. The controlled-compressibility formulation is engineered to compress under glass pressure without squeezing out or allowing the glass edge to make direct contact with the pinchweld, which helps protect both the glass and the vehicle body during and after installation.

This sealer is used in automotive glass replacement applications, including windshield and rear backlite installs on passenger vehicles. It is suitable for both shop and mobile auto glass technicians performing OEM-style replacements. The kit format is designed to support single-unit replacements, making it practical for individual service calls or production-line glass work. Setting blocks are included to properly position and support the glass during the cure and set period.

Key Features

• Controlled compressibility prevents sealer squeeze-out during glass installation
• Keeps glass edge from contacting the pinchweld flange directly
• 1/4-inch diameter round ribbon profile for consistent bead placement
• 15-foot roll provides sufficient coverage for one full windshield or backlite
• Kit includes setting blocks for proper glass positioning
• Pre-formed ribbon format reduces application time compared to gun-applied sealers

Compatibility

Designed for use in automotive windshield and backlite replacement applications where a round ribbon butyl sealer is specified. Suitable for passenger vehicle glass installations requiring a pinchweld-style sealing method.

Installation Notes

Auto glass technicians should follow the vehicle manufacturer's glass replacement procedure and all applicable safety guidelines before beginning installation. Ensure the pinchweld surface is clean, dry, and free of old sealer residue before applying the ribbon. Use the included setting blocks to hold the glass at the correct height and prevent direct contact between the glass edge and the pinchweld. Avoid stretching the ribbon during application, as this can reduce the cross-section and compromise the seal.
