Appliance foam without adhesive

This replacement foam strip is made for residential air-conditioners. It fits two Keystone portable models and eighteen Midea units sold through multiple retailers in 2016. The part is supplied new and sold individually.

No adhesive means installer choice

Because the foam arrives without pre-applied adhesive, the technician selects the bonding method that suits the cabinet material and service conditions. This avoids mismatched tapes that can fail under vibration or condensate exposure.

Lightweight open-cell structure

The foam compresses easily to seal irregular gaps around evaporator housings and drain pans. Its flexible profile allows quick fitting during routine maintenance without specialized tools or cabinet modifications. Buyers needing a pre-glued gasket or a rigid insulator should look elsewhere.

Questions about this item

How often will the foam without adhesive need to be replaced in my residential A/C unit?

The foam is a passive seal component; it has no defined service interval and is typically replaced only when it becomes brittle, torn, or loses its shape during a repair or seasonal check.

What is the first limit that appears when the foam is used continuously in a Keystone KSTAP12A or KSTAP14A air conditioner?

The first limit is physical degradation — the foam can compress, crumble, or detach over time because it lacks adhesive, so it relies on surrounding parts to hold it in place.

Does the foam generate any noise, heat, or extra power draw when the air conditioner runs all day?

No. The foam is a non‑powered insulation and sealing part; it adds no electrical load, produces no heat of its own, and makes no sound during operation.
