Broad 2-inch coverage for wide substrate surfaces — flawlessly even distribution of adhesives and sealants per pass

Excels in faying surface sealant applications — consistency and coverage paramount to structural integrity

Specially formulated materials — durable against harsh industrial solvents and adhesives, solvent cleanable between uses

Seamless integration with all Semco® disposable cartridges and Semkit packages — 1 oz through 1/10 gallon

Replacement rollers available separately — extends investment lifespan, cost-effective serviceability

The 2-inch roller width delivers flawlessly even distribution of adhesives and sealants across wide substrate surfaces — maximizing coverage per pass and ensuring uniform material application across the entire contact area. This broad coverage capability is particularly critical for faying surface sealant applications where consistency and coverage are paramount to structural integrity and performance, eliminating the voids and uneven distribution that compromise joint reliability in aerospace and industrial assembly.

This professional-grade applicator excels particularly in faying surface sealant applications where consistency and coverage are paramount to structural integrity and performance. Faying surface sealing between mating structural components in aerospace and industrial assembly demands the flawlessly uniform sealant distribution that the 2-inch roller delivers — ensuring complete surface coverage, eliminating dry spots, and providing the consistent sealant film thickness required for reliable structural joint performance.

The precision-molded roller base is constructed from specially formulated chemically resistant materials, ensuring durability even when exposed to harsh industrial solvents and adhesives. This resilient construction allows for thorough solvent cleaning between applications, making the roller nozzle a reusable, cost-effective solution for professional contractors and industrial applications — eliminating the ongoing cost of single-use applicators while maintaining consistent, reliable performance across every application.

The robust 1/4 inch NPT male threaded connection seamlessly integrates with Semco®'s complete range of disposable cartridges and Semkit packages. Comprehensive compatibility spans across 1, 2.5, 6, 8, 12, 20, 32 oz. and 1/10 gallon sizes — providing flexibility for projects of any scale. This standardized NPT threading delivers consistent, leak-free connections across the entire Semco® cartridge range, eliminating compatibility concerns and ensuring reliable performance in every application.

When the roller eventually shows signs of wear, replacement rollers can be purchased separately, extending the lifespan of your investment. This intelligent serviceability design means you replace only the wear component — not the entire precision-molded roller base assembly. This cost-effective approach delivers long-term value for professional contractors and industrial operations where roller nozzles are used frequently across high-volume adhesive and sealant application projects.

Available in both one-inch and two-inch widths — providing application flexibility for projects requiring different coverage widths. The 2-inch width maximizes efficiency for broad surface coverage in faying surface and wide substrate applications, while the 1-inch width delivers precision coverage for narrower joint sealing and targeted application areas. Both widths feature the same robust 1/4" NPT male thread, chemically resistant construction, and full Semco® cartridge compatibility.
