Perfect distribution where components meet — optimal sealing conditions for critical assemblies

Advanced chemically resistant materials — exceptional durability, extended service life, maximum ROI

Workflow continuity — seamless integration with all Semco® cartridges & Semkit, 1 oz through 1/10 gallon

Available separately — cost-effective maintenance ensuring continued precision in sealant application processes

Meticulously designed to deliver uniform, consistent coverage across wide substrate areas — transforming your sealant application process with unparalleled efficiency and professional results. The precision-engineered roller mechanism ensures consistent application quality throughout its extended service life, delivering the reliable, repeatable performance that aerospace, industrial, and professional contractor operations demand for every critical assembly.

This sub-assembly particularly excels in faying surface sealant applications — ensuring perfect distribution and coverage where components meet, creating optimal sealing conditions for critical assemblies. The 1-inch roller width delivers targeted, precise coverage for standard joint widths and faying surface sealing operations — ensuring complete surface contact, eliminating voids, and providing the consistent sealant film thickness required for structural joint performance in demanding aerospace and industrial applications.

The precision-molded roller base is crafted from advanced chemically resistant materials, providing exceptional durability even when exposed to harsh industrial solvents and chemicals. This resilience allows for thorough cleaning and repeated use, maximizing your return on investment while maintaining consistent application quality throughout its extended service life — delivering the long-term cost savings and performance reliability that professional industrial operations require.

The 1/4" NPT male threaded connection seamlessly integrates with Semco®'s complete range of disposable cartridges and Semkit packages, accommodating 1, 2.5, 6, 8, 12, 20, 32 oz. and 1/10 gallon configurations. This comprehensive compatibility ensures workflow continuity across various project requirements without additional equipment investments — standardizing your dispensing system across all project scales from precision spot applications to large-volume industrial sealant distribution.

Replacement rollers are available separately, allowing for cost-effective maintenance of your application system while ensuring continued precision in your sealant application processes. This intelligent serviceability design means you replace only the roller wear component — not the entire precision sub-assembly — delivering maximum long-term value and uninterrupted operational continuity for professional contractors and industrial operations with high-frequency sealant application requirements.

The 1-inch configuration provides optimal targeted coverage for standard joint widths and precision sealant placement. For projects requiring different coverage widths, the system is also available in a 2-inch configuration to accommodate larger application areas — providing complete application flexibility across your full range of adhesive and sealant projects. Both configurations feature the same robust 1/4" NPT male thread and advanced chemically resistant construction.
