Buying Guide

Match tape material to surface

Choose tapes formulated for EPDM, rubber, metal, or plastic to ensure proper adhesion and chemical compatibility with drain pan materials

Select appropriate width

Wider tapes cover larger gaps and seams faster while narrower rolls are easier to conform to tight corners and outlets

Consider peel-and-stick strength

Look for tapes with high initial tack and permanent bond characteristics to resist moisture, vibration, and thermal cycling

Check UV and weather resistance

For exposed or outdoor drain pans, choose UV-stable sealant tapes to prevent degradation and loss of adhesion over time

Evaluate ease of application

Microsealant and conformable backing makes installation quicker and reduces the need for primers or secondary adhesives
