Foam in Place Gasket & Sealing

November 2, 2017 | Category: Gaskets, Type 4x Enclosure

Foam-in-place gasketing and sealing is an adhesive dispensing equipment system that works in a variety of applications, but for our purpose specifically, as a dust sealing and cushioning application for our standard and custom manufactured enclosures.

Foam-in-place gasket (thixotropic) is a two component modified polyurethane resin that serves as the ultimate gasket for various enclosures, including UL Type 12, 4, and 4X.

Steeline Enclosures has tested this process time and time again, and we now have proof that the gasket provides a superior resilience, excellent compression recovery, and to top it all off, it is UL approved.


It has a superior adhesion to many kinds of substrate, and with no seams or joints to leak, our products have a continuous bead that provides fantastic enclosure coverage.


For quarter turn latches and swing handles on NEMA 4 enclosures, there is no separate gasket. Say goodbye to losing or forgetting to install.

Using a wide, more compliant, UL polyurethane foam gasket ensures improved sealing. Because it’s UL listed, urethane gasket material resists oil, water, ozone, chemicals, and weathering, ensuring that that the electronics within the steel enclosure are safe, sound, and monitored.
