Research Products 4896 Styrofoam Door Seal

Product Description

The RESEARCH PRODUCTS 4896 is a styrofoam door seal designed to maintain an airtight closure on compatible air treatment units. Door seals of this type prevent conditioned or treated air from bypassing the filter or media section, keeping system efficiency high and protecting downstream components. This part is installed by HVAC technicians and service professionals performing routine maintenance or unit restoration. At 0.10 pounds, the 4896 is a lightweight replacement component suited for fast field swaps.

This door seal is specified for use with the RESEARCH PRODUCTS Model 1413 air treatment unit. It is typically encountered in residential and light commercial HVAC applications where whole-house air treatment or humidification equipment is installed inline with the duct system. Proper door sealing is essential to ensure the unit operates as designed and does not allow unfiltered or untreated air to pass around the media section.

Installation Notes

Remove the old seal completely and ensure the door channel is clean and free of debris before seating the new seal. Verify the door closes fully and latches securely after installation to confirm proper sealing.
